We spend hours and hours in front of screens, especially those who work with them and cannot look away. But not only in the work environment, they have also taken over all activities associated with spending free time to a large extent: video games, series and movies, video calls. This overexposure To screens can cause Eye fatigue, loss of vision, or headache.
Blue light is part of the electromagnetic spectrum with wavelengths between 380nm and 500nm. This light is essential for clear, high-contrast vision. But it can also have negative effects on the health of our eyes and general. Prolonged exposure to blue light can cause eye strain, which is characterized by symptoms such as heavy eyelids, itching, drowsiness, burning, dry eyes, and redness. Additionally, photophobia, blurred vision, or double vision are other common effects in this type of condition. also It can cause headaches, dizziness, and interfere with sleep. By affecting the production of melatonin, the hormone that regulates the sleep cycle.
In some cases, it is possible to reduce exposure to this external factor. For example, choosing other forms of entertainment that do not include video games, computers, televisions or mobile phones. However, this is complicated in the case of work. Therefore, the solution that can be used is Mitigating the effects of artificial light:Glasses with blue light filter.
Many people claim that they do the job and reduce the harmful effects of screens. However, a review of the research suggests that these blue light-filtering glasses will not make any difference to eye strain, eye health, or sleep quality, at least in the short term. That said, it’s still It is not clear whether these glasses protect against retinal damage.Because the research did not evaluate it, according to the results published in the Cochrane Database of Systematic Reviews.
“We found that there may be no benefit to using glasses with blue light filtering lenses in reducing computer-related eye strain, compared to lenses that filter blue light.” It does not filter blue light.“It is not yet clear whether these lenses affect vision quality or sleep outcomes, and no conclusions can be drawn about any potential long-term effects on retinal health,” said Laura Downey, lead researcher and director of the Downey Lab at Harvard University in Victoria, Australia.
The researchers reviewed 17 randomized controlled trials from six countries. The size of the studies ranged from just five participants to 156. The duration of the studies ranged from one day to five weeks. “People should be Aware of these results “When they decide to buy these glasses,” Downey added in a Cochrane press release.
