![]() ![]() There are types of IOL that can protect the eye and retina from blue light. The lens naturally protects the eye from almost all ultraviolet light and some blue light. Intraocular lens (IOL): After cataract surgery, the cloudy lens will be replaced with an intraocular lens (IOL). They decrease the amount of blue light given off from these devices that could reach the retina in our eyes.Ĭomputer glasses: Computer glasses with yellow-tinted lenses that block blue light can help ease computer digital eye strain by increasing contrast.Īnti-reflective lenses: Anti-reflective lenses reduce glare and increase contrast and also block blue light from the sun and digital devices. Screen time: Try to decrease the amount of time spent in front of these screens and/or take frequent breaks to give your eyes a rest.įilters: Screen filters are available for smart phones, tablets, and computer screens. If constant exposure to blue light from smart phones, tablets, and computer screens is an issue, there are a few ways to decrease exposure to blue light: What Can You Do to Protect Your Eyes from Blue Light? This can cause vision problems like age-related macular degeneration. Retina damage: Studies suggest that continued exposure to blue light over time could lead to damaged retinal cells. Symptoms of eyestrain include sore or irritated eyes and difficulty focusing. Fatigue, dry eyes, bad lighting, or how you sit in front of the computer can cause eyestrain. Early research shows that too much exposure to blue light could lead to: parts of the eyeĭigital eyestrain: Blue light from computer screens and digital devices can decrease contrast leading to digital eyestrain. This light may affect vision and could prematurely age the eyes. ![]() Early studies show a deficiency in blue light exposure could contribute to the recent increase in myopia/nearsightedness.Īlmost all visible blue light passes through the cornea and lens and reaches the retina. Not enough exposure to sunlight in children could affect the growth and development of the eyes and vision.Too much exposure to blue light late at night (through smart phones, tablets, and computers) can disturb the wake and sleep cycle, leading to problems sleeping and daytime tiredness. Exposure to blue light during daytime hours helps maintain a healthful circadian rhythm. It regulates circadian rhythm – the body’s natural wake and sleep cycle.It boosts alertness, helps memory and cognitive function and elevates mood.According to a recent NEI-funded study, children’s eyes absorb more blue light than adults from digital device screens. And yet, there is concern over the long-term effects of screen exposure because of the close proximity of the screens and the length of time spent looking at them. Computer monitors, smart phones, and tablet screensīlue light exposure you receive from screens is small compared to the amount of exposure from the sun.In addition, there are many other sources: The largest source of blue light is sunlight. ![]()
