Exposure to blue light can harm your eyes!

Blurry vision, eyestrain, dry eyes and macular degeneration are a few problems caused by the blue light as we spend hours staring at screens without realizing the harm it does to our eyes. Digital eyestrain and retina damage are the adverse effects that it leaves us with. Hence, people are often suggested to use screen filters while using their phones or laptops. These filters help in reducing the exposure of blue light that reaches the retina of our eyes.

Effects of blue light on the retina, and sleeping schedule

Blue light reaches straight to the back side of the retina and leads to permanent vision changes. As the retina is the initial stage of how our vision is formed this is the place where the root of many eye infections or diseases begins. It can easily penetrate through the lens and reach the retina causing retinal photochemical damage. Your screen time before bed is directly proportional to the quality of your sleep. The blue light from screens creates issues in the circadian rhythm (a natural, internal process that regulates the sleep-wake cycle and repeats roughly every 24 hours). 2 hours of exposure to blue light is more than enough to slow or stop the release of the sleep hormone melatonin.ย 

How can you protect your eyes from blue light?

Reduce the exposure to sources of blue light (smartphones, tablets, and computer screens) when not required and avoid it three hours before bedtime. Take frequent breaks when using it for prolonged periods. Screen filters and computer glasses are best to block or at least lessen the harmful effects of blue light. Anti-reflective lenses are also recommended to reduce the glare directly from the sun as well as digital devices.
