365Telugu.com online news,August 20,2023:Excessive use of mobile and laptop is considered to have harmful effects on eyes. In fact, the blue light emitted from it not only causes problems for the eyes but also affects the quality of sleep and the body in many other ways. should be effective. To avoid such side effects, you have often seen people wearing blue filter glasses.
These glasses are believed to filter the blue light emitted from the screen and help reduce the side effects. But how true is this? Are these useful..?
The question arises because a recent study by a team of researchers debunks this claim. Even if you wear blue filter glasses while working on a screen, they are actually not that effective in reducing eye damage, say scientists.
The researchers said the glasses were not beneficial in reducing blue light damage or sleep problems. Eye problems such as eye strain and dry eyes are seen in people exposed to excessive blue light. Blue-filter glasses are believed to reduce these risks, but researchers in studies have found that they are not beneficial at all.
Study..?
The study, published in the Cochrane Database of Systematic Reviews, examined data from 619 people collected from 17 clinical trials in six countries. These blue light-filtering glasses were not found to be beneficial in preventing computer fatigue, meaning that blue light does not cause eye damage, said senior author Laura Downey, an optometry and vision scientist at the University of Melbourne.
Due to increased use of mobiles and laptops during the Covid-19 pandemic, researchers have found that many problems related to blue light are becoming more common among people.
Blue filter glasses
Do these lenses affect the quality of vision or sleep problems due to blue light? Scientists said that is also unclear. The potential impact of these glasses on retinal health in the long term is also unknown, they said.
Researchers report that the amount of blue light emitted from computer screens and other artificial sources is only one-thousandth of the blue light emitted during the day. In such situations there is no need for such glasses. Furthermore, blue light lenses typically only filter 10 to 25 percent of blue light.
To keep eyes healthy..
Health experts say that if you use a computer or any other screens a lot during the day, you can do some exercises to protect your eyes from the side effects.
