Danger of blue light for your eyes

In the visible light spectrum, there is a segment called short-wave blue light that is perceived as blue in color but can also be present when light is perceived as white. Exposure emitted from the sun and digital devices are associated with causing sleep disruption, eye fatigue, and possible damage raising your risk for certain eye diseases. Thankfully, there are blue light contacts and glasses that you can use to filter out the harmful light wavelengths before they reach your eyes.

What is blue light? Is it harmful?

Each color of the light spectrum has a unique wavelength and energy level. Blue light, compared to other colors, has shorter wavelengths and more energy. According to certain studies, short-wave blue light with wavelengths between 415 and 455 nanometers is associated with eye damage. In smartphones, TVs, and tablets, LEDs produce light at wavelengths between 400 and 490 nanometers. The overuse and exposure to blue light from cell phones and other devices can have dangerous effects.

Children may be more vulnerable to the effects of blue light because their eyes don’t filter blue light like adult eyes. Too much screen time may increase their risk of developing nearsightedness. It can also decrease their release of melatonin at night. Limiting screen time is beneficial to children's eyes overall. Start good habits like putting away gaming devices at least 30 minutes before bedtime to help them sleep.

Dangers of blue light for your health

High-energy sunlight in big doses, such as UV and blue rays, can also increase your chance of developing eye diseases. According to experts, roughly 50% of computer users experience digital eye strain. Vision blurring and dry, itchy eyes are common symptoms of this.

Your retinas may also be harmed by blue light. Even brief exposure (from a few minutes to a couple of hours) may impact your eye health, according to research. It has been found that blue light risks to your vision are lessened when applying a filter that blocks 94% of blue light.

Dangers of blue light for your eyes

Blue light can cause long-term eyesight problems, so it’s best to take precautions when exposed to blue light. Almost all blue light travels directly to the back of the retina, which can accelerate the age-related decline in vision. According to certain studies, the dangers of blue light from screens include the risk of the retinal disease macular degeneration.
