Before the controversy generated in social networksespecially in ‘X‘(previously known as Twitter), the Organization of Consumers and Users (OCU) has decided to prepare an article on its website, based on scientific evidence, to demonstrate to humanity if they really serve something or not.
In depth
Apparently, this product is designed exclusively for minimize The amount of blue light that reaches the eye. A light that, In the opinion of this organismit’s no more “that a visible light spectrum fraction“Interestingly, both people can use them They do not have a perfect vision like those that do.
“There are those who affirm that The overexposure in blue light As appropriate of electronic devices I could damage the eyes, be harmful to vision and get to cause sleep problems“The entity has revealed forcefully.It is true or not?
More details

In all these, different aspects such as visual fatigue, visual acuity, diurnal alertness and sleep quality were measured. About the former, “there were no significant differences Among the people who had wear glasses with filter and glasses without filter”
To take into account
With respect to Visual acuitythe OCU has asserted that it was concluded that there were no differences between the people who had wear glasses and others. The same happened with clinical studies that measured the effect of the filter on Diurnal alertness and sleep quality.
Therefore, The OCU has argued that the conclusions presented by the authors of the Cochrane review is that, in the short term, “possibly glasses with blue light filter Do not reduce visual fatigue associated with the use of screens. “As if that were not enough, they have expressed that Nor do visual acuity improve.
“It is not known if they could improve sleep quality. To this day, and with scientific studies in hand, There is nothing that endorses the effectiveness of the glasses with filter for the blue light“He has ended.
