Tips to avoid harmful effects of computer and smartphone screens on your eyes | Health


Computer screens have always been the proverbial double-edged swords where on the one hand they help us in all kinds of activities from business to entertainment, from health consultations to online courses, from stocks and finance to online shopping, while on the other hand, they play a major role in creating health issues, especially in the eyes. It was fine until the time when computers were lying in a room and we could only access them when we finished our day and took some time but now computer screens are in our eyes almost all the time which wakes up in the form of mobiles, tab. , laptops, office screens and even watches and the effect it creates has not only become stronger but also longer and all harm the eyes of the users.

Our digital devices are a sight for sore eyes, literally. If you are one of those people who look at their digital devices more than 7 hours a day, your eyes are probably paying the price of your screen addiction because looking at your digital screens for a long time can lead to fatigue, itchy, dry eyes and even blurred vision and headaches.

Computer Vision Syndrome (CVS) ranges from mild to severe and involves eye redness, dryness, fatigue, fatigue with headache, sleepiness, eye pain, shoulder and back pain and blurred vision. well near and far. This leads to reduced productivity and intractable symptoms of the affected person.

In an interview with HT Lifestyle, Dr Anuradha Ghorpade, Consultant Ophthalmologist at Connect and Heal, revealed, “In children, especially those who spend a long time playing mobile phone games, along with its impact on memory and logical thinking, Screen time increases the chances of inducing high refractive errors (high power glasses) which in the long run has its own problems and complications. Also due to constant rubbing of the eye due to fatigue, there is a high possibility of eye infection including styes and conjunctivitis which can also spread to others due to physical contact with touched hands.

He pointed out, “In some people, especially the elderly who have a small space in their eyes (narrow angles) often close to work can cause an attack of acute glaucoma that appears which is severe pain, redness and blurred vision. This is an emergency and may require admission and laser treatment. Some people also suffer from dark circles and wrinkles around their eyes. eyes not only due to lack of sleep but perhaps also due to blue light from computer screens. Blue light is also known to affect sleep patterns and cause retinal issues in the long run. This may include of age-related retinal changes and central vision issues.

According to Dr Anuradha Ghorpade, among all these problems, dry eyes and visual dependence are the two most common problems. He said, “Dryness can cause a constant gritty sensation, blurring due to dry spots and intermittent watering. Contact lenses increase dryness and are not recommended for computer users. The power of the scene continues to change in young users while in the old it shows fluctuations that cause intermittent blurring. Therefore it is recommended to reduce the time on the screen to the minimum possible and as much as necessary.”

He suggested, “Also, have your eyes checked by an eye specialist if in doubt. The diagnosis of dry eyes and related diseases can only be done in a clinic with various tests and equipment available there such as the OSDI questionnaire, Schirmer test, tear separation time and Fluorescein staining. Once the diagnosis is made, treatment can be started in the form of eyedrops, eye gels and tablets. Along with this, he recommends the following precautions to be followed:

– Use anti-reflective glasses or screens

– Keep the computer at a 45 degree downward angle

– Always close your eyes

– Use eye moisturizing eye drops during and after screen time

– Eat lots of fresh green and red/orange vegetables and fruits

– Follow the 20-20-20 rule which means that every 20 minutes look at a distance of 20 meters for 20 seconds to break the eye muscles and the surface of the eye.

– Do not sit in front of the AC directly

– Sleep for 7-8 hours and drink 2-3 liters of water per day

– Get out in the sunlight regularly especially for children as this has been shown to reduce the chance of developing glaucoma.

– Limit the use of mobile phones by children to the minimum possible for the overall development of the child, and involve the child in alternative activities instead of flirting.

Dr Rashmi Shukla, Consultant Ophthalmologist (Cataract, Cornea and Anterior Segment Specialist) at Mahim’s PD Hinduja Hospital & MRC, advises, “For people who spend a lot of time on the computer, it is recommended to use a larger screen. The screen should be placed at least 65 cm away and slightly below eye level. Use anti-glare mode on laptop/mobile screens. Place the screen so that light from natural or artificial sources does not fall directly on the screen or in your eyes. The light from the screen should not be too bright or too dull. Get your prescription glasses made of anti-reflective/anti-glare coating. Blink often while working on the screen and take frequent breaks from on the screen to focus on objects at a distance Use a cool mist humidifier to change dry air quality and stay well hydrated.

Saying that with luck you can minimize the inevitable digital eye strain, Dr Rashi Taori Sawal, Sr. Consultant at Sharp Sight Eye Hospitals, lists some simple, healthy habits to incorporate into your digital device-viewing routine:

1. Keep your eyes moist by blinking about 12-15 times per minute and you should be good to go. It keeps your eyes moist and reduces dryness and irritation. Blinking also helps focus your eyes.

2. Being too close to your digital screen is another factor in how your eyes can be negatively affected—they have to work harder to see things closer. If possible, keep your devices about 25 inches apart, or about an arm’s length away. Be sure to position the screen so that your eye view is adjusted slightly downward.

3. Make sure you adjust the brightness of your screen before using it. When a screen is brighter than the surrounding light, the eyes have to work harder and can be one of the causes of eye strain.

4. You can also tweak your text size and contrast according to your convenience. Adjusting the contrast and size of text on your devices provides some much-needed comfort and makes reading web content, email messages and more easier.

5. Keep your digital screen clean. Regularly wipe the screen of your devices with a dry clean cloth to remove distracting dust, dirt, smudges and fingerprints.

6. Limit things before you go to sleep. Studies show that blue light from your phone and other screens can affect the body’s natural sleep-wake cycle. During the day, blue light wakes us up and motivates us, while at night it does the same thing, making it difficult to fall asleep. If necessary, use night time settings on devices and computers that reduce exposure to blue light.

Meanwhile, if you experience frequent dry, red eyes or eye pain, schedule an appointment with your ophthalmologist. Following the above precautions, one can take good care of their eyes, however, if one is facing eye problems, the best thing to do is to visit the eye doctor and not self-medication to avoid wrong treatments and further aggravation”.
