Are you frequently looking at a bright screen after the sun goes down?
If yes, you are not the only one; the majority of us spend a lot of time staring at screens. This could be harmful for our eyes. Electronic devices’ blue light has been related to issues like cataracts, macular degeneration, dry eyes, blurred vision, and eyestrain, and some people have trouble sleeping.
The visible light spectrum, which the human eye can see, includes blue light. It has the shortest wavelength and most energy and vibrates in the 380–500 nanometer range.
Blue light is thought to make up around one-third of all visible light. Sunlight is the chief source of blue light. There are other sources as well, including:
The amount of blue light exposure you get from screens is less in comparison to what you get from the sun. Yet, due to the close proximity of the screens and the length of time spent staring at them, there is worry about the long-term effects of screen exposure.
Although blue light is difficult for our eyes to filter, almost all of it enters through the cornea and lens of the eye and travels to the retina, where the cells transform it into images for the brain.
Over time, constant exposure to blue light may harm retinal cells and result in vision issues, including age-related macular degeneration. Children are higher at risk than adults because their eyes absorb more blue light from digital devices.
Digital eyestrain can result from prolonged or close-up use of digital devices.
People tend to blink less frequently when using computers, laptops, and other digital devices than usual. Less blinking may indicate less moisture.
When your eyes get tired from staring at a blue-light generating screen, you might observe:
Blue light Exposure before bedtime disturbs your sleep patterns as it affects when our bodies produce melatonin. Type 2 diabetes, cancer, cardiovascular disease, sleep difficulties, and cognitive dysfunctions can all be caused by an interruption of the circadian rhythm.
You can take the following steps to reduce digital eyestrain:
If you’re exposed to blue light, which is released by either your cellphones, computers, or bright lights, it can inhibit your sleep and cause a lot of eyestrain. We would recommend reducing your exposure to blue light if you have a history of sleeping problems or fatigued eyes.
