In today’s digital world, screens are everywhere. From laptops to smartphones, our eyes are constantly glued to devices. This has led to a rise in complaints like eye strain, dryness, and headaches.

Computer glasses are specially designed eyewear to help reduce eye strain caused by prolonged screen use. Dr Rahil Chaudhary, Managing Director - Eye7Hospital, New Delhi, explained it saying, “Unlike blue light glasses, which primarily block blue light, computer glasses have a mild convex lens power (+0.25).” This small but significant feature helps your eyes focus better on screens, reducing the strain caused by diverging light.
How Do Computer Glasses Work?
When you look at a screen, the light emitted is diverging, meaning it spreads out as it reaches your eyes. Your eye muscles have to work harder to focus on this light, leading to fatigue and strain. Computer glasses have a convex lens that converges the light slightly, making it easier for your eyes to focus.
According to Dr Chaudhary, “The light coming from near is diverging. A convex lens helps you converge it, so your eye muscles don’t have to work as hard. The muscle that usually works 100% now only works 50%. This gives you a slight but noticeable benefit.” This reduction in effort can make a big difference, especially for people who spend hours in front of screens.
When Should You Wear Computer Glasses?
The expert advised wearing computer glasses whenever you’re using a screen. This includes not just computers and laptops but also smartphones and tablets. Many people assume that smaller screens like phones don’t require computer glasses, but this isn’t true. “Wear them all the time whenever you are on screens. Whether it’s a laptop, computer, or phone, computer glasses can help,” added the expert.

Tips for Eye Comfort
While computer glasses can significantly reduce eye strain, they’re not the only solution. Here are some additional tips by Dr Chaudhary to keep your eyes comfortable during long screen sessions:
Use Lubricating Eye Drops
Dry eyes are a common problem for people who spend hours on screens. The expert recommends using preservative-free lubricating drops like Refresh Tears. “Put this 3-4 times a day during long hours of screen time. You will feel much more comfortable,” they say.
A common concern is whether it’s safe to use eye drops frequently. The expert reassures, “There is no harm in putting them again.” However, overuse may cause some problems.
Follow the 20-20-20 Rule
Every 20 minutes, take a 20-second break and look at something 20 feet away. This simple habit can help relax your eye muscles and reduce strain.
Adjust Screen Settings
Make sure your screen brightness and contrast are set to comfortable levels. Avoid using screens in overly dark or bright environments.
Position Your Screen Correctly
Your screen should be about an arm’s length away and slightly below eye level. This reduces the strain on your neck and eyes.

Computer glasses are generally safe to use. However, some people may experience mild discomfort when they first start using them. This is usually because their eyes are adjusting to the new lens.

If you’re considering computer glasses, consult an eye care professional to find the right fit for your needs.
