What is Nearsightedness?

Nearsightedness or short-sightedness also referred to as myopia is the condition where the distant objects are seen blurry while close objects appear normal. This is an eye disorder where light focuses in front of the retina instead of on the retina. Headache, squinting, eye strain, and fatigue are a few common symptoms of nearsightedness. 

Combinations of environmental and genetic factors are considered as the cause of nearsightedness. Family history, engaging work focusing on closer objects, spending a lot of time indoors are considered as risk factors for this condition. Nearsightedness can be treated by wearing glasses, contact lenses, or can get cured permanently through LASIK surgeries.

Computer Vision Syndrome (CVS) 

Electronic devices are a part of our lives where most of our work relies on these devices. Apart from work, we also use digital devices for other purposes such as education, information, to connect with family and friends, for entertainment such as watching movies and TV series, and much more. 

Studies show that an adult spends an average of 12+ hours a day in front of a digital screen. As a result of this prolonged use of digital devices a condition called computer vision syndrome (CVS) can take place. This illness is popular amongst everyone irrespective of age and can eventually lead to nearsightedness.

This is also referred to as digital eye strain, a condition that is caused by focusing the eyes on a computer or other electronic devices such as TV, smartphones, tablets, etc for a long period without interruptions. As a result of this, many people experience eye discomfort and vision problems.

How Does It Occur?

The blue lights from computers, televisions are claimed to have biological effects, majorly to the eye causing damage to the retinal cells and age-related macular degeneration. Therefore ophthalmologists suggest following the 20:20:20 rule wherein every 20 minutes a person should take a 20 seconds break by focusing on an object at a distance of 20 feet away.

Studies show that staying outdoors can lower the risk of getting nearsightedness. Unfortunately, due to the higher usage of electronic devices, not only adults but children also tend to spend less time outside. As a result of this device overuse, ophthalmologists have to keep increasing the prescriptions of nearsightedness.


It is essential to relax your eyes, blink your eyes more often while on-screen, and to have regular comprehensive eye checks at eye clinics to check the status of your eyes. Also, those with nearsightedness can undergo Lasik surgeries like SupraLasik or Ultra Lasik to correct the vision permanently.
