Digital eye fatigue</h3><p>Digitalization has become inevitable and so has the stress on the eyes and vision. We are constantly exposed to digital gadgets and laptops daily, with education going digital, kids are now prone to eye impairments and vision disabilities.</p><p>The growing stress on the eyes due to excessive and prolonged exposure to laptop, tablets, mobile, and computer screens lead to a condition called digital eye strain and it further complicates the computer vision syndrome.&nbsp;</p><p>The vision syndrome occurs due to repeated back-and-forth movement of your retina on the screen which requires constant focusing and refocusing. Your eyes tend to become hypersensitive to changing images and fonts that tend to exhaust your eye muscles.</p><p>This overuse of technology causes great strain on the user's eyes. One main effect technology has is causing eye strain, headaches, focusing difficulty, double vision, etc.&nbsp;</p><p>Without looking at technology, a user's eye blinks 12-15 times a minute. However, when a user is focusing on a digital screen, they forget to blink. This can lead to a user blinking only 7 times a minute. The decrease in blinking can lead to less lubrication which results in dry and extremely sore eyes.</p><ul><li>It is estimated that 50-90% of people who work on computers have reported digital eye fatigue symptoms.&nbsp;</li><li>Digital eye fatigue (also known as asthenopia) has a variety of <a href="https://www.megawecare.com/good-health-by-yourself/eye-health/dry-eyes" target="_blank">side effects</a> including dry eyes, difficulty focusing, headache, tiredness, and light sensitivity.&nbsp;</li><li>Eye fatigue is linked to the prolonged use of any technology permitting light such as TVs, laptop/computer screens, mobile phones, and tablets.</li></ul><h3 id="retinal-damage">2.

The most common symptoms of computer vision syndrome include:</p><ul><li>Dry eyes</li><li>Headaches</li><li>Light sensitivity</li><li>Blurred vision</li><li>Itchy or watery eyes</li><li>Eye strain</li></ul><p>Depending on the patient, these symptoms can range from mild discomfort to severe eye health problems.&nbsp;</p><p>If you are experiencing any of these symptoms and constantly use electronic devices like a computer screen, you may be suffering from computer vision syndrome.&nbsp;</p><h3 id="headaches-and-migraines">4. Headaches &amp; migraines</h3><p>The most common negative effect of screens on the eyes is experiencing a headache or even a migraine.&nbsp;</p><ul><li>When you stare at a screen for an extended period, eyestrain will most likely occur and can cause tension headaches.</li><li>Typically, the contrast between the brightness of the screen and the darker text makes our eyes work harder than they need to, ultimately triggering eye strain and headaches.&nbsp;</li><li>For some patients, this pain may be more severe and cause a migraine. Unfortunately, migraines can quickly cause other symptoms like nausea, light sensitivity, and temporary blindness.</li></ul><h2 id="how-to-take-better-care-of-your-eyes">Take better care of your eyes</h2><h4>1.
