How Do Anti-blue Glasses Protect Eyesight?

With the amount of time we spend on our devices increasing, it's probably no surprise that staring at a screen for long periods can hurt your eyes. A new product is emerging to help reduce potential side effects of being glued to a screen all day, blue light glasses that filter or absorb rays from sources of blue light such as phones and computer screens.

1. What Are the Effects of Blue Light?

Too much blue light can contribute to issues like sleep dysfunction and possibly eye strain and headaches.

Although digital devices emit blue light at a low frequency not likely to damage vision, prolonged exposure can lead to insomnia, abnormal sleep patterns and eye strain, according to Dr. Samuel Pierce, president of the American Optometric Association.

“Eye strain in and of itself will not cause permanent damage, there’s no long-term lasting effects from eye strain,” said Pierce. “It typically goes away when you stop the activities that are creating the eye strain.”

Eye strain is a common side effect of looking at a screen for too long and can lead to headaches, neck or shoulder pain and blurred vision. Both the Vision Council and Pierce recommend using anti blue light glasses to make it easier to look at a screen and alleviate these symptoms if you associate your eye strain with digital use.

The biggest source of blue light is the sun, which signals our body to be and stay awake. Melatonin is produced when blue light becomes less extreme, and it helps us fall asleep. However, with artificial blue light emanating from our phones and computers, it becomes more confusing for the body to know when to produce melatonin, therefore, it is more difficult to fall asleep.

2. How Do Anti-blue Glasses Protect Eyesight?

Clear blue light glasses help filter/block bright blue light that is emitted from electronic devices.

The anti blue ray spectacles reduce the high energy blue light emitting from computer or mobile screen. Wiping out the most harmful blue light, these anti blue light goggles allow you to watch the screen for a long time and also lessen the fatigue and tiredness of eyes. These prescription glasses with anti blue light also help in reducing light distortion due the usage of low light distortion lens.

The blue light blocking glasses is specially designed for the reduction of the most damaging blue light rays. These blue ray glasses can filter out almost 90% high energy blue light that ranges from 400nm to 430nm, and only allows a small amount of less harmful blue light, thus giving us a long time to watch any screen for a long time without any fatigue and tiredness.

Overall, research focused on the effects of blue light filtering glasses is lacking, and opinions differ about whether or not they are necessary. However, some people find they reduce symptoms like eye strain, dry eyes, blurriness, tension headaches and trouble falling asleep if they wear blue light eyeglasses, especially among people using electronics for many hours daily and at night.
