Worried about eye strain in the digital era? Are your devices affecting your sleep? Are you using Blue-Light Blocking glasses?

Eye fatigue has become very common in today’s digital era and is the first symptom of eye strain. Many people are experiencing pain behind or around the eyes, with a burning or stinging sensation, the area might feel sore or tired. However, this goes away once you have rested your eyes. But are you getting sound sleep?

The major cause of eye fatigue and disturbed sleep today is mostly exposure to the Blue light emitted by devices we expose ourselves to each day. Exposure to digital screens can cause symptoms like headaches, dry eyes or blurred vision when moderation isn’t practiced.

However, what’s the solution?

Divesh Pahwa a leading Delhi based optician who owns a chain of optical stores says, “Blue light blocking glasses can help reduce eye strain as blue light can make it difficult to focus on the screen. Blue light glasses also help increase contrast on your screen, making it easier to focus and reduce eye strain”. These glasses are also known as computer glasses and can be bought with both prescription and non-prescription. He says, the sale of blue lenses has gone up by 70% in the last year since people are constantly on their devices and experiencing severe eye fatigue. He recommends Zeiss, Essilor and Nikon as good quality lenses you can use in your glasses.


DuraVision® BlueProtect by ZEISS

This is a coating specially developed for people who spend a lot of their time indoors and are exposed to blue-violet light from LED’s as well as TV, computer or tablet screens. These lenses reflect parts of the blue-violet light emitted by these sources, preventing light from entering the eye. ZEISS offers a comprehensive blue-violet light blocking portfolio that meets different consumer requirements for indoor and outdoor activities, filtering different amounts of blue-violet light depending on the activity.


Eyezen by ESSILOR

Eyezen is a new lens technology from Essilor that helps to protect against the harmful effects of screens; they not only protect your vision in front of digital screens but also help your vision focus when switching from one screen to another, such as from your computer to your phone.

Eyezen lenses are specially enhanced for your computer, TV and smartphone usage to keep your eyes relaxed and protected. They have been engineered with 3 exclusive technologies, Eyezen focus, Light scan & WAVE technologies.


Pure Blue UV Pro by NIKON

Nikon has come up with a new technology combined with SeeCoat called Pure Blue UV Pro, a lense that filters UV and blue light, combined with an additional blue coating for the ultimate protection against blue light and an effective eye strain relief. It comes with superior quality and durability for everyday use.



According to Dr. Geetika Bindra, a leading Kolkata based Ophthalmologist, blue light blocking glasses are most beneficial if used at night as Blue light is similar to day light. However, exposure to this light at night tricks the body into believing it’s still day time which suppresses the production of melatonin essential for sleep and delays sleepiness and affects both the quality and quantity of your sleep. Thus disrupting the sleep-wake cycle, which is crucial for optimal health.

Use Blue-Light Blocking glasses to keep your eyes healthy, reduce digital eye strain and get sound sleep.
