Astăzi trăim o perioadă mai lungă, iar celulele pielii și ochilor au nevoie de o protecție suplimentară împotriva radiațiilor. 54% din radiațiile infraroșii care ajung la noi provin de la soare. Acest lucru are efecte cumulative și poate accelera degenerarea retinei și a cristalinului, ducând la cataractă.
De asemenea, are un efect fototermic care crește evaporarea lacrimilor, provocând un disconfort mai mare. că radiația infraroșie contribuie la distrugerea colagenului în zona ochiului, cauzând, la rândul său, riduri pe piele.

Known for its phototoxicity, capable of quickly causing harmful and irreversible effects on eyes and skin. The ozone layer only filters a part of these radiations; the rest of UV radiation, in particular UVB and UVA, can reach the cornea where they cause inflammation of the anterior segment (uveitis, conjunctivitis, queratitis), pinguecula, pterygium, desquamation of endothelium. UVA radiation also reaches the crystallin causing opacity, which can lead to cataracts.

Nowadays we spend many hours in front of electronic devices with screens that emit a higher proportion of blue light than the Sun, which is what our eyes have adapted to through evolution. This excess of blue light is potentially harmful and must be filtered properly. Failure to do so can result in symptoms such as visual fatigue and tiredness. It is also true that blue light has accumulative phototoxic effects on the retina and crystallin.

In addition, blue light also affects the hormone that regulates sleep, melatonin, therefore an excess of hours prior to sleep disturbs its natural cycle.
