Infrared light (IR) is an electromagnetic radiation that the sun emits invisibly with a wavelength between 780 nm and 1 mm whose main effect is the heat it provides. However, this IR emission has a harmful component in the human eye, which began to manifest itself at the beginning of the industrial revolution when welders or metal or glass workers began to present retinal burns or incipient cataracts.
Currently, it is considered that the main effect of IR radiation on the lens is accelerated aging, causing cataract, due to oxidative processes caused by temperature and heat exchanges. This excessive exposure anticipates the opacification that was destined to appear over the years, especially in the stage of old age.
The effect of IR radiation on the retina, with the increase in temperature, is the denaturation of the enzymes. These enzymes are called matrix metalloproteinases (MMPs), which act in the maintenance and remodeling of tissue architecture. It has been shown that the increase in these MMP-2 favors the development of AMD due to acute or chronic exposure to IR radiation.
Among the benefits of our lens we can highlight that:
• Neutralizes harmful blue light avoiding fatigue and visual stress
• Helps prevent Age-Related Macular Degeneration • Offers 25% more protection against UV rays than other lenses
• Provides 35% less cell death in the retina
• Prevents damage to the cornea due to ablation and opacity of the lens (Cataract)
• Blocks infrared light that accelerates the production of alkalines in the body causing tissue aging
• Cancels the effects of thermal stress
• It is the only ophthalmic lens in Mexico with 100% blue, UV and infrared light protection.
• Features a hydrophobic coating that repels dust and rain, so you'll have cleaner glasses for longer.
• Prevents the appearance of fine lines around the eye.
Regarding its wavelength, blue light is below 400 nm (ultraviolet zone) and above 750 nm (infrared zone). This is why being exposed to it for a long time becomes dangerous for our eyes, because it can damage the photoreceptors and retinal cells. Some of the problems caused by prolonged exposure to blue light are:
Computer Visual Syndrome (SVI): Red eyes. eye strain eye dryness Decreased blink rate. disturbance of circadian rhythms
Due to its short wavelength and high energy, blue light partially suppresses the synthesis of melatonin, this is the sleep hormone, causing insomnia as a consequence. Being exposed to blue light without protection is dangerous for visual health, its effects are cumulative and chronic, and even cause complicated photochemical damage.
