More health for our eyes: they create a filter that "exploits" the malicious blue light of the screens


Eyes get more stimulus electronic objects. Scientists are trying to avoid the so-called and the effects blue light tablets and mobile phones

Fernandez-Vega Ophthalmology Institute (IOFV), Ophthalmology Research Foundation (FIO), Asturias Institute of Technology (ITMA) and Oxford University published in scientific journal & # 39;Optical materials& # 39; s a business that analyzes the benefits of a filter not just malicious light blocks, as it has happened so far, is also a useful source of light for the retina.

Goal? Findings can be used to prepare "lenses" neuroprotective and therapeutic for patients glaucoma and Age-Related Macular Degeneration (DMAE). "Key, blue, will not be harmful as the" red light ".

Light blue and so on. red light

Professor Neville N. Osborne and Dr. Susana del Omo, according to the FIO's main inspectors, is that untreated blue light interacts with certain pigments present in the retina, can damage it. On the contrary, red light stimulates tissues and has the potential confrontation these losses. Therefore, the modulation of the amount of red light could be useful for certain patients.

Difference with existing filters at present. ITMA researcher and author of the article Amador Menendez, "The use of ophthalmology filters is not new, but so far filters absorptive (lightens the light and loses its heat) or photonic crystals (reflecting the light of certain waves). "

"This new type of filter, known as luminescent filters, provides spectral redistribution with potential double effects of the light: neuroprotector (by damaging malicious UV-blue light) and therapeutic (providing additional IR redness that stimulates the retina cells renewal), says nanophotonics expert.

New glasses

This filter can be entered into the lens, without significantly modifying vision. Andrés Fernández-Vega Cueto-Felgueroso, an ophthalmologist and researcher, said that this study was born with the idea that it would offer added value to the current treatment.
