Scientists have proven blue light filters don't affect sleep patterns

In modern society, a stablethe opinion that blue light causes insomnia and interferes with a person's good rest. Exploiting this idea, many manufacturers have created glasses with blue light filters, smartphones use a color gamut shifted towards the red spectrum. This is due to concern for the user's nervous system. However, according to the neurologist Tarek Yusef, the significance of the influence of blue light on a person is exaggerated and is used to obtain not always justified profit.

The scientist believes that the theory about the influence of bluelight on human sleep cycles appeared after the discovery of the melanopsin molecule associated with eye neurons that send signals to the suprachiasmatic nucleus. It is in this core that our internal "biological" clock is regulated, which determines the time and quality of sleep. Melanopsin, in turn, is exposed to blue light, which provided an opinion that this spectrum is excessively harmful to a person's sleep cycles.

Meanwhile, today there are no clinicaldata supporting the benefits of using lenses with a blue light filter. At the moment, this is another pseudoscience market that has a very wide consumer base - all computer users. At the same time, studies have appeared in which it is argued that melanopsin reacts to other light spectra, although to a lesser extent.

Studies have shown that one of the most likelyThe total time we spend in front of the screen is the cause of eye irritation and fatigue. As a result of fewer blinks, the surface of the eyes dries up.
