In today’s daily life, computers have taken over every aspect of human life. Our home, workplace, school, and personal life are surrounded by digital screens almost all the time. The only time people don’t stare at a screen is when they are asleep; this trend, although inevitable, comes with a severe cost for our vision, says ocular health expert Dr. Tom Chang MD. The professional term for what the specialist is talking about is “digital eye strain” and it can come from laptops, smartphones, tablets, and any other screen that emits blue light. Most of these devices receive a lot of viewership, especially now during the pandemic when many people have been shifting to digital platforms for everyday activities. 

Specialized ophthalmologist Dr. Tom Chang acknowledges that currently it is almost impossible for people to avoid using these devices and cautions against excessive exposure to them. Some of the symptoms that Tom Chang MD points out for digital eye strain include dry eyes with blurry vision accompanied by headaches and pain in the shoulders and eyes. He also credits poor posture and lighting combined with an excessive viewership of these blue-light emitting devices. 

The experienced eye surgeon Dr. Tom Chang advises the user of computer screens of any size and any kind of device to practice protective guidelines to prevent serious medical conditions. He recommends simple solutions like looking away from the screen for a short period, like 20 seconds for every 20 minutes spent on the screen; it is the 20/20/20 rule to avoid eye strain. Tom Chang MD states that a safe distance between the user and a screen should be at least 28 inches away. Another point to consider is maintaining good posture when using any device; slouching and leaning when using the computer should be avoided. The anti-glare filter can also be used to protect the eyes as well as soft lighting.
