ABSTRACT

As the COVID-19 epidemic continues, when it comes to studying at home or working from home, there are no escape devices. They serve as an important link in human life and learning and the working environment. As with any useful tool, certain digital devices can sometimes be "very good." The COVID-19 epidemic has led to increased use of digital devices, which poses a greater risk of developing digital eye symptoms. Eye care professionals should educate patients about screen time limitations and digital eye signage management, leading to the challenge of annual visual programs. The effects of ocular surface health and circadian rhythm abnormalities associated with ocular disease such as computer vision syndrome, dry eyes, astigmatism, near vision, muscle mass etc. are increasing. In this covid epidemic 19 the widespread use of Herbal medicine and the use of Ayurvedic medicine increases when conventional medicine does not work in the treatment of diseases. Ayurveda is considered to be one of the best remedies for disease and lead to a healthy lifestyle in ancient India. Trataka treatments and head rubbing are also a good exercise for eye health. Oncological diseases ayurvedic remedies such as Haritaki, Malaki, Vibhitaki, Alovera are widely used. Triphala is a powerful Ayurvedic tonic containing three traditional fruits that have long been used to treat various health conditions of ocular disease. This is a traditional eye procedure and is very easy to keep the eyes healthy. Ginkgo biloba is used in traditional medicine recommended to enhance vision.

INTRODUCTION

The eye is quite possibly the most intricate organs in the human body. There are three layers to the natural eye. The external locale comprises of the cornea and sclera. The cornea likewise sends and communicates light to the focal point and retina and shields the eye from disease and underlying harm in the more profound parts. The sclera frames a layer of connective tissue that shields the eye from inside and outside powers and keeps up with its shape. The cornea and sclera are associated with the limbus. The noticeable piece of the sclera is covered by a reasonable mucous film, the conjunctiva. The center layer is comprised of the iris, the ciliary body and the choroid. The iris controls the size of the understudy, so the measure of light arrives at the retina; the ciliary body manages the energy and organization of the focal point and is a wellspring of water creation; and choroid is a layer of conduits that supply oxygen and supplements to the external layers of the retina. The inward layer of the eye is the retina, a perplexing, complex design of tactile nerves that catches and cycles light. The three most clear constructions encompassed by visual layers are called water, glassy and focal point [1-3].

In this Coronavirus pandemics, home seclusion, E-learning in and telecommute caused expanded utilization of computerized gadgets, representing a more serious danger of creating advanced eye stressed side effects and other eye-related issues. Eye inconveniences are normal result of being an understudy or worker in a virtual climate. Individuals invest such a lot of energy on PCs and versatile, web-based media, staring at the television/film it is causing visual sickness. Eye issue ought not be disregarded. There are issues which happen because of virtual climate like eye consuming, dry eyes, and cerebral pains. Eye care proficient ought to instruct patients about restricting screen time and overseeing digitals eye strains disorder [4].

On account of Coronavirus, home isolation, E-learning and schoolwork have prompted expanded utilization of advanced gadgets, which represents a more serious danger of computerized signage and other eye-related issues. Eye issues are a typical aftereffect of being an understudy or a task in an apparent climate. Individuals invest a ton of energy on PCs and mobile phones, via web-based media, sitting in front of the TV/films-practically inescapable sicknesses. Eye issues ought not be neglected. Issues happen because of actual factors like a burn from the sun, dry eyes, and migraines. Eyecare experts ought to teach patients about screen time cutoff points and control strains disorder [5].

As the COVID-19 plague proceeds, numerous parts of our lives are unsure, and better approaches for learning can influence kids' lives from various perspectives, including their perspectives like, More and more computerized learning will make its own challenges, Some youngsters may not hear an opportunity to get the point of view tests they generally get at school-which regularly makes a spot to breeze through a total eye assessment, Parents may not know what vision issues resemble when kids are learning at home. In the shortfall of true leave or outside sports exercises, kids might invest less energy on physical activities [5].

Working from home causes PC vision illness in grown-ups and individuals between the ages. When chipping away at a PC, your eyes ought to consistently be engaged a lot. Go to and froth as you read. You might have to peer down the papers and return to composing. Your eyes react to steadily evolving pictures, moving center, and sending prompt pictures to the mind. These exercises require a great deal of exertion from your eye muscles. Furthermore, to compound the situation, in contrast to a book or a piece of paper, the screen adds differentiation, splendour, and brilliance. Likewise, it is demonstrated that we squint regularly when utilizing a PC, which makes dry eyes and obscured vision from time while working. PC work turns out to be more troublesome as you develop more established and the normal focal points in your eyes become more adaptable. Somewhere else in your 40's, your capacity to zero in on all over is probably going to be restricted. Your eye specialist will call this condition presbyopia [5].

There is no evidence that computer use causes any long-term damage to the eyes. In any case, normal use can prompt eye strain and distress. Symptoms include: Blurred vision, blurred vision, thirst, red eyes, irritation of the eyes, headache, neck or back pain [5].

There are several ocular problems due to the visible nature of the eye:

Computer vision syndrome: symptoms caused by prolonged viewing of a computer screen or other digital device screen.

Muscle type: Stretching or tearing of a muscle or tendon. The remains usually appear on the lower back and posterior muscles of the thigh. Symptoms include pain, swelling, muscle stiffness and muscle tightness. Treatment may include pain relief, ice, or fractures.

Dry eyes: A dry eye that occurs when the tears do not provide enough moisture. The danger of fostering this condition increments with age. It is also commonly seen in postmenopausal women. The eye may be dry, red, and inflamed. The fundamental manifestations are distress and affectability to light. Eye contact and eye drops can reduce thirst.

Astigmatism: A common defect in the eyelids. With astigmatism, the front of the eye or the inner lens of the eye is bent differently on one side than the other. The most common sign is blurred vision. Treatment includes doctor's glasses or contact lenses. Laser-helped a medical procedures, like LASIK, can likewise help.

Nearby sight: A situation where nearby objects appear clearly, but distant objects do not show. Close-ups often run in families. The distant objects seem to fade. The condition can develop gradually or rapidly. Treatment options include glasses, contact lenses and surgery such as LASIK [6].

In India, Ayurvedic care offers the largest program through a fully functional network of registered staff, research centres and licensed pharmacists. Ayurveda, Yoga, Naturopathy, Unani, Siddha and Homeopathy (AYUSH) are well-known medical programs and have been integrated into the national health care system. Of these, Ayurveda is an ancient medical system with an impressive record of safety and effectiveness. There is a growing awareness, nationally and internationally, of the need to incorporate the contributions of these health information systems into greater compliance with modern medicine limits. A study on the role of AYUSH and Local Health Traditions under the auspices of the National Rural Health Mission (NRHM) in 18 provinces across India, was studied. The pivotal outcomes and perceptions conclude that 80-90% of households aware about utility of AYUSH and Local health traditions (LHTs), co-located services are well utilized in some states, and preference was for chronic illness followed by acute illness and health promotion [7-10].

Ophthalmology (shalakyatantra) is one of eight Ayurvedic-related medical treatments for the management of eye diseases including all other head and neck problems. Ayurvedic eye diseases and treatments are well-known, but their effects are still felt and recognized by medical organizations and the general public. Apart from extensive research and application of various scientific and technological advances, problems with the management of conditions such as retinitis pigmentosa, glaucoma, degenerative neuroophthalmic ulcers, chronic adnexa diseases remain unresolved for decades. With this in mind it is very important to develop and evaluate confidential medical information for better management of such ocular conditions [11].

Ayurveda offers comprehensive and effective ways to manage such situations. Many traditional indigenous eye systems have been severely damaged by the search for tangible evidence of safety and effectiveness; call for scientific research and validation. Ayurveda presents different concepts and principles for the management of eye diseases and the efforts being made to prove the effectiveness of its methods [12-15].

Various plant can provide various therapeutic effects such as improving eye vision, and strengthening eye sights and useful in ophthalmology treatment such as anti-inflammatory, anti-fungus etc.

There are several plants and plant’s part are used which provide various therapeutics effect on eyes. Ayurvedic plants like Amlaki, Haritaki, Vibhitaki, Tulsi, Punernava, Palash, Ginkgo biloba, Kalonji, Graecum etc.

Computer vision syndrome

It is also known as digital eye type, which is defined as eye-related problems caused by the use of a computer, tablet, e-reader, laptop and cell phone. Many individuals experience eye distress and vision issues when watching digital screens for significant stretches of time. The issue-level is ascending with the utilization of digital screens [16, 17].

The normal American worker goes through seven hours every day at the PC either in the workplace or at home. To help reduce digital eye strain, follow rule 20-20-20; take a 20-minute break to watch something every 20 meters every 20 min [18, 19].

Children should be taught how to stay away from screens and for how long. They often adapt to illegal working conditions and pay attention to specific complaints. It takes a lot of work to address the gaps in our knowledge. When there are no major lessons, it is reasonable to assume that children should spend only enough time needed before devices. This will deal with the child's obesity epidemic as well. Over time, we can see that our fears have not been supported but until we make technology completely safe for children, we must develop caution [20].

Causes and risk factors

Observing a computer or digital screen continuously often makes the eyes work harder. As a result, the unique features and high visibility requirements of computer and digital screen viewing make more people inclined to develop vision-related features. Irritating vision issues can build the seriousness of PC vision disorder (CVS) or advanced eye indications. Long-term computer viewing is different from reading a printed page. Often the characters in a computer or in a handheld device are not defined accurately or precisely, the comparative level of the background characters decreases, and the availability of bright light and screen appearance can make viewing difficult. Viewing the distances and angles used for this type of activity are also often different from those used for other reading or writing activities. Accordingly, the vision and eye development prerequisites in a computerized screen survey might put extra necessities on the visual framework. In addition, the presence of minor vision problems may significantly affect comfort and performance on a computer or while using other digital screen devices. Inadequate or undergoing corrected vision problems can be major causes contributing to computer-related difficulties. Even people with eyeglasses or contact lenses may find that they do not fit certain viewing angles on their computer screen. Some people are tilting their heads in opposite directions because their mirrors are not designed to look at a computer or they bend down to the screen to see clearly. Their posture can lead to muscle aches or pains in the neck, shoulder or back. In many cases, CVS symptoms occur because the visual needs of the work exceed the visual perception of a person to do it well. Those most in danger of creating CVS are the individuals who go through two hours or even more persistently at a PC or utilizing a digital screen gadget consistently [18-20].

Symptoms:

• Headaches.

• Blurred vision.

• Dry eyes.

• Neck and shoulder pain.

These symptoms can be caused by:

• Poor lighting.

• Brightness on the digital screen.

• Incorrect viewing distances.

• Poor living conditions.

• Unresolved vision problems

The level at which individuals experience visual signals regularly relies upon the level of their visual abilities and the time spent taking looking at the digital screen. Unresolved vision problems such as farsightedness and astigmatism, poor eye focus or eye coordination skills, and eye agility, such as presbyopia, can all help to improve visual acuity when using a computer or digital screen device. Most of the symptoms visible to users are temporary and will go away after stopping computer operation or the use of the device. However, a few groups might keep on decreasing their visual sharpness, like obscured vision, and even get-togethers quit working on a PC. In case nothing is done to tackle the reason for the issue, the indications will proceed to repeat and maybe deteriorate with the utilization of future computerized screens [18, 19].

Pathophysiology

The focus of the human eye is not the same as the printed text and visual display unit but it provides feedback in a variety of ways. Each printed letter is made up of a well-defined letter throughout its space, and VDT characters are made up of pixels above the screen. Each pixel is illuminated in its center and with dim light to the other side. So that human eyes can strengthen focus on pixel letters. Instead, the focus program stays behind the computer screen due to the precise position of the computer user's preferred position in relation to reading printed text. This point is called the black focus. So, the eyes are always at rest in the dark or in the dark and striving to get the focus on the pixel character on a regular basis. This repeated and repeated focus on the ciliary body causes eye fatigue and causes permanent symptoms associated with CV. This lag of residence leads to ocular symptoms associated with CVS. Notwithstanding these, the pictures framed by pixels and raster need sharp edges thus which makes an under the incitement of convenience and causes linger of convenience behind the screen because of obscured characters of writings [21-25].

Diagnosis

CVS, or computer-assisted eye fatigue, can be diagnosed with a comprehensive eye examination. Testing, with an exceptional emphasis on visual requirements on a PC or computer gadget's operating range, may include Patient history of determining any manifestations a patient experiences and the presence of any broader medical conditions, medications taken or genetic variables that may add to the indications identified for PC use. Visual sharpening measurement to assess the extent to which the view can be influenced. It also decides to determine the appropriate concentration strength that is expected to be made for any retrieval errors (partial blindness, blurred vision or astigmatism). Exploring how the eyes are in the middle, how they move and how they interact. To get a clear picture, one of which is visual, the eyes must adequately alter the center, move and function as a joint. This test will look at the problem that prevents the eyes from concentrating properly or making it difficult to use both eyes together. In this experiment, the eye drops may not be used to determine how the eyes respond under normal visual conditions. In some cases, for example, when part of the focus of the eye may be combined, eye drops may be used. They briefly held the eyes back from changing the concentration while the test was completed. Using the data from these tests, in addition to the results of a separate test, an optometry specialist may determine the presence of CVS or computer-assisted fatigue and recommend alternative therapies [18, 19].

Treatment

Viewing the computer

Body posture suitable for computer use. Other important factors in preventing or reducing CVS symptoms are related to the computer and how it is used. These include lighting conditions, the comfort of the chair, the location of appliances, the monitoring area, and the use of leisure breaks.

Fig. 2: Position of viewing the computer

Prevention

Preventing or minimizing vision problems associated with CVS or digital eyestrain includes taking steps to control brightness and brightness on the device screen, establishing performance scales and good screen viewing and ensuring that minor vision problems are properly corrected.

Suggestions for patients with computer vision syndrome:

Dry eye

Dry eye incidence of 10.1-21.5% among office workers has been reported from different subgroups in Japan. It is hypothesized that dryness, consumption, dirt, or greatness after a lengthy meeting at the workstation might be ascribed to visual surface issues. Clients' eyes sometime even hyperlacrimate trying to re-establish the compound equilibrium and rewet the eye. Environmental factors like dry air-conditioned interiors, draught from ventilation fans, static build-up, airborne paper, and general office dust can have some bearing on the ocular surface symptoms [26, 27].

The level of blinking while working on a computer has been reported to be significantly lower than normal. This leads to a low level of tear film. Lower browsing rate decreased from 22 per minute free and up to 10 per minute while reading the book and 7 per minute on VDT in a study of 104 office workers. However, the quality of the tear film measured by the duration of the tear, the experiments of Schirmer I and Jones were not significantly affected while using the computer. Various blink patterns have been described in patients with the disease but none of them have been proven in subsequent studies. Blink values found to decrease with reduced font size, reduced variation, increased job demand, and space between characters and lines. The words with a combination of major and minor cases are better tolerated than all major case documents. It is recommended that spacing between characters and lines should allow for half a character space between words and a single character space between lines. The black letters facing the small back light screen are better received in contrast to the contrast. The use of elastoviscous drops is not associated with the development of blinking levels. A study of 112 non-computerized contact lenses found that 68% of men and 73% of women reported symptoms of dry eye [26-31].

Studies based on videokeratoscopy have shown that the optical system of the cornea is adversely affected by a set of the tear film. Ocular fatigue has been associated with ocular dryness in the past. Increased evaporation and decreased blinking during computer use lead to changes in the ocular surface and as a result were believed to lead to eye fatigue. The frequency of dry eye has been accounted for to increment with age. The predominance of dry eye and is more normal in women than in men. Artificial tears can be helpful for this group with dry eye conditions. Other than that, it does nothing to reduce symptoms. Often, the view changes from the printed word to the screen and vice versa is associated with eyestrain and should be addressed. The snatching was said to mean eyelash extraction by Sheedy et al. And was believed to reduce the level of blinking but recent research has shown that the symptoms were mild when swelling was used in laboratory conditions. Dry eye has been reported to be the cause of eye strain and its associated symptoms in the subcategory. Evidence of intent is still disputed in the matter [32-37].

Improving eye health with ayurveda

Let's try to understand the importance of eye care according to Ayurveda and learn simple ways to incorporate eye care techniques into our diet and lifestyle to prevent such issues.

The eyes are considered the seat of the pitta dosha and require proper care, cooling and regular brushing. If the blink of an eye is much lower than normal, this cooling and softening process is interrupted, thus increasing the chances of complications related to eye pressure. If it's not too much trouble, see beneath a portion of the eye care tips suggested from Ayurveda [38].

Ayurvedic eye care tips

Always rinse your eyes with cold water in the morning. This removes dried mucus and dirt that has accumulated in the eyes and stimulates the eyelids. The eyes always benefit from the cool creation.

Don’t use any chemical beauty products around the eyes. Try using Ayurvedic Kajal or eyeliner daily treatment to cleanse and nourish the eyes.

Regular head massage is good for improving circulation around the area and relaxing the muscles needed to maintain the ability to look and rejuvenate the tear glands. You can use coconut oil or any of its medicinal varieties.

Fig. 3: Head massage

Palming the eyes

Rub the palms of your hands quickly for 10 seconds and wrap your hands over them. Avoid putting any pressure on the eyeballs. Rest in this position for 2-3 min, then try to repeat every 30 min especially if you are very active on the screens. Take a deep breath and look at the space in front of your eyes.

Try to stay in the shade and avoid direct exposure to strong sunlight. Wear a hat or good protective glass if you are sitting outside for several hours [38].

Trataka meditation

Exercise is also an important factor in maintaining good vision and eye health. The traditional way to do this would be by meditating on the so-called trataka view in Yoga. According to the ancient book, 'Hatha Yoga Pradipika', trataka is defined as 'a steady, steady gaze from a small point to tears.' This is one of the shat kriyas or six cleansing methods described in Hatha Yoga, and they also help to cleanse and heal the eyes [38, 39].

Ayurvedic herbs used in ocular disease

Apply a cotton swab dipped in cold frozen water over the eyes for 10 min once daily to relax and clean the eyes. This will also reduce the tendency for dark circles around the eyes. Cucumber slices are also considered good.

Strain the aloe vera meat into a cube large enough to hold your finger well and freeze separately. When the eyes feel tired, take one cube out of the fridge and rub the face and the area around the eyes at the same time every day preferably in the evening. When the cube is finished, keep your cold finger on the eyes to calm them down [38].

Triphala

Also known as the "three fruits", Triphala is a powerful Ayurvedic tonic with three traditional fruits that have long been used to treat various health conditions-Amla or Amlaki (Emblica officinalis), Haritaki (Terminalia chebula) and Bibhitaki (Terminalia belerica). This is a traditional eye procedure and is very easy to keep the eyes healthy [38].

Haritaki

Its plant source is Terminalia chebula and is called Chebulic Myrobalans in Latin. Charaka even says that Haritaki is as nourishing and beneficial to everyone as mother's milk. He talks about it as an eye rasayana, which is why it can be used to prevent eye infections. It helps to improve agni, and thus improves the absorption of nutrients from the digestive system supported by various studies. Another good quality of this fruit is that it cleans the major circulatory channels, known as shrotovishodhini, meaning that it can clear channels, larger and smaller, called sarvah dosha prasamani (silences all-doshas), and fewer fruits and herbs with this name. It also supports the immune system. Above all, Haritaki has an anti-aging value "vayasthapani" (anti-aging). Therefore, it is recommended to prevent age-related eye disorders such as age-related macular degeneration (ARMD), Senile Cataract, Open-angle glaucoma and Retinal degeneration [39-41].

Fig. 7: Haritaki fruit

Vibhitaki

The source of the plant is Terminalia bellerica. It is said to be the leading homeostatic, which means it helps to control the internal environment especially the circulation of pure blood in the body. It is a good herb for the peace of both Pitta and Kapha. Acharayacharaka quotes vibhitaki as netrehitam, which means it is beneficial to the eyes and cleanses Rasa (plasma), Rakta (blood), Mamsa (muscle tissue) and Medo dhatus (tissue) adipose) when they act as dushyas (mature tissue) in the pathophysiology of disease formation [42].

Fig. 8: Vibhitaki

Amalaki

The source of the plant is emblica officinalies. It helps to cleanse the body of toxins, by increasing the absorption of food. When our metabolism is strong, the food we eat is converted into nutrients rather than digested and produces impurities (aama). Therefore, it removes toxins from the body. The eyes are another vital organ in malachi's case. In fact, the amalekites are called chakshusya, meaning “eye-catching rasayana [38].

This is because Amalaki develops both Ranjaka Pitta (one type of Pitta that regulates liver function and blood composition) and Alochaka Pitta (another type of pitta that controls the object of the eye/vision). Due to its high content of Vitamin C, Amalaki is a powerful antioxidant. Scientific research shows that Amalaki is a very powerful antioxidant, very effective in removing many free radicals, which are the basis of degenerative disease and aging. All of these qualities make Malachi an invaluable immune system [43-45].

Fig. 9: Amlaki

Make Triphala tea in distilled water using 1 tsp of powdered water in 200 ml. Strain the liquid when it is cold, using a cotton swab. Apply this cold solution in a face wash for both sides for 5-7 min. The astringent effect of Triphala berries causes a burning sensation but only at the beginning. Once the eyes are accustomed to it, it feels cool and comfortable. This is good to do once in the evening, and it works (endless) dry eyes, red eyes, and irritated conjunctiva.

Ginkgo biloba

Today, Ginkgo biloba is used in traditional medicine around the world. The remedy is widely used to support mental health as a brain tonic and to improve blood circulation in the body. Like natural antioxidants, the pot is considered beneficial for the eyes and is often recommended for strengthening or protecting eyesight. Due to its widespread use in natural medicine, herbs have become the subject of numerous studies. Their antioxidant properties protect them from stress-causing eye damage, but studies show other vision benefits. A study in Korea found that extracting ginkgo helped many people with glaucoma improve their vision. Ginkgo is one of the remedies for epilepsy due to its neuroprotective effects [46-50].
