The following article addresses digital induced eye strain and effective remedies for improving the condition; while also considering whether the use of “blue light glasses” are effective
Also known as "Computer Vision Syndrome", this condition occurs from sitting for extended periods of time in front of a computer screen or while using other digital or electronic devices such as tablets, TV, e-readers, and smartphones. When we have excessive exposure to digital screens, we have a tendency to blink less, which increases the strain on our eyes. Fortunately, there are many steps you can take to reduce or eliminate these symptoms.
Blue light is part of the visible light spectrum emitted by the sun. Proponents of blue light glasses argue that they can reduce the effects of this exposure which they maintain is harmful, causes ocular strain, and impairs sleep.
The American Academy of Ophthalmology reports that a recent study found no evidence suggesting that such light damages our eyes. As a result, they do not recommend such glasses. (There was some evidence linking such light exposure to possible effects on the body's circadian rhythm or “internal clock”).
Most experts reject the unproven claim that blue light emitted by digital devices is excessive enough to cause ocular strain. While these symptoms are certainly uncomfortable, adopting the techniques below will reduce these unpleasant effects.
There is no reliable evidence to prove the efficacy of such glasses or that such light exposure leads to eye disease. Rather than purchasing such glasses, there are many steps you can take to reduce the effects caused by overuse or misuse of electronic devices.
Common symptoms from excessive exposure to digital screens include:
Fortunately, with proper corrective measures these are only temporary effects. There is no evidence that long-term exposure causes ill effects on vision or overall optical health.
There are plenty of easy and effective solutions to prevent eye strain. The following techniques have brought relief to many people:
Blue light is part of the visible light spectrum, and most of our exposure to it comes from the sun. Most experts reject the claim that it causes eye strain and that special protective glasses can reduce these effects. There is no conclusive evidence to prove these assertions or to suggest that special glasses can reduce these symptoms. By adopting better habits, you can reduce these effects, without resorting to buying glasses whose purported efficacy is questionable and unproven.
