Computer Vision Syndrome (CVS) is the visual fatigue caused by prolonged use of computers, smartphones, tablets other digital devices. It is also known as eye strain from computer or digital eye strain. Computer or screen use accounts for over 75% of our everyday activity. Sixty million computer professionals around the world suffer from computer eye strain.
Maximum patients visiting the optometry clinic experience eye strain from computer with the following symptoms:
Computer Vision Syndrome progression is influenced by several factors, including:
Along with the screen, two more factors cause eye strain from computer. It includes blue light emission from the screen and reduced blinking while watching it.
The computer screens emit blue light and require the eyes to constantly adjust focus and align, which causes eye strain and fatigue. Blue light is a high-energy visible light emitted by computers, smartphones, tablets, and televisions. Blue light penetrates deeper into the eye and causes more retinal damage than other colours. It also disrupts the sleep-wake cycle. That is why we experience eye strain, headaches, and dry eyes on prolonged screen exposure.
In addition to blue light, screens can cause eye strain and fatigue because they require the eyes to adjust focus and alignment constantly. Screens make our eyes track moving images while watching a video or playing a game, which can cause additional eye strain. Unlike printed text, which is usually fixed and stable, digital text can appear blurry or pixelated, requiring the eyes to work harder to focus.
Blinking is essential for keeping the eyes moist and lubricated. However, we tend to blink less than usual while using a screen. Furthermore, we tend to blink less while focusing on the screen, which causes dry and irritated eyes.
Using the screen at full brightness mode makes it difficult for your eyes to adjust the contrast between the bright screen and the surrounding environment. It also causes glare, which is the reflection of light off the screen’s surface. Glare can cause discomfort and make it difficult to see the screen. It can lead to eye discomfort, fatigue, and headaches.
Bright screens also disrupt our natural sleep-wake cycle by suppressing the production of melatonin, a sleep-regulating hormone. Excessive bright screen exposure before bedtime can make it harder to fall asleep and cause sleep disorders.
While sitting in front of the screen continuously, we can have dry eyes, and neck and shoulder pain due to poor sitting posture. A regular break from the screen after 20- 30 mins can help reduce eye strain, prevent our eyes from drying, and relieve tension in the neck and shoulder muscles.
Regular breaks from the screen can also reduce stress and improve our work productivity by enhancing focus and concentration. Research has proven that short breaks can boost mental clarity and increase productivity.
Additionally, taking short breaks to stretch or walk around can keep us physically active, increase blood circulation and reduce the risk of obesity, heart disease, diabetes, and other seating problems.
If you are dealing with CVS, you are at high risk of developing more severe visual problems such as:
Sitting in front of the screen is unavoidable. However, there are a few changes that you can implement to reduce and prevent digital eye strain from computer.
Also, get routine eye checkups to diagnose underlying eye problems and ensure your glasses or contact lens prescription is current. By implementing these tips, you can reduce eye strain from computer use and prevent more serious eye problems.
Frequently Asked Questions
Get enough rest and wear glasses or contact lenses to relieve headaches. Positioning the screen at the appropriate distance and height can also reduce headaches.
You can use a cold compress by placing a chilled ice pack over your closed eyes. It is the most effective tired eyes remedy to reduce swelling and soothe the eyes. You can also place the rose water-soaked cotton ball or cucumber slices over the eyes for a soothing effect. Eye exercises such as focusing on distant objects, rotating your eyes, and blinking rapidly for a few minutes can also help to reduce eye strain from computer.
Eye strain can resolve within a few hours to a few days with rest and self-care measures. If you experience persistent or worsening eye strain despite self-care measures, consult an eye doctor for a thorough diagnosis.
Blue light glasses can help cut a significant amount of blue light that enters the eyes, which reduces eye strain and improve sleep quality. Blue light is the high-energy visible light emitted by smartphones, computers, and televisions. It can contribute to eye strain, headaches, and disrupted sleep.
