How Does Blue Light Affect Your Eyes?

Blue light

Blue light is a high-energy light emitted by the sun and digital screens; this light can penetrate past the cornea to the retina of the eye. In addition to the exposure of blue light from the sun; nowadays, several studies have shown that an adult can be exposed for around 12 hours  to blue light coming from digital devices in a day! This is not just during the day but extends up to late hours of the night as they mindlessly scroll through their mobile phones, extend their working hours on computers, or watch movies. This overexposure to blue light can be overwhelming for the eye and it may lead to a number of problems, how ever two of the most common are:

Digital Eye Strain

It is also known as computer vision syndrome and it’s one of the most common temporary effects of using digital devices for long periods. Its symptoms include blurred vision, red, teary and sore eyes, epicanthal folds, back and neck pains, or sleeping difficulty. It is caused by the intense concentration of blue light on your eyes; staring at your screen without blinking, and the glare of light that bounces off the screen and into your eyes.

Although this is a temporary condition that you experience during and shortly after using devices, if it keeps on happening often it will lead to more serious eye conditions.

Macular Degeneration

This is a condition that mostly occurs as you age and it involves the breaking down of cells in the retina. The permanent damage on the retina compromises the area of the eye which is responsible for clear vision; consequently people suffering from macular degeneration will experience blurred vision. Overexposure to blue light accelerates the development of this condition since the high energy waves are concentrated on the retina.

Blue Light Glasses
