Protection From Harmful UV & Blue Light
Neochromes lenses help protect your eyes by blocking 100% harmful UVA and UVB rays while also reducing blue light exposure. When outdoors, the lenses automatically activate to provide added comfort, glare reduction, and enhanced eye protection in bright sunlight.
Maximum Protection
Neochromes lenses help wearers care for their eyes by blocking 100% of damaging UVA and UVB rays. They also filter blue light, especially when activated outdoors. While blue light is emitted from computers, tablets, and smartphones, sunlight is a much more intense source of blue light.
Blue Light Filtering
Neochromes lenses offer maximum protection against these potentially harmful wavelengths of light.
WHAT IS THE BLUE LIGHT?
Blue light is present in visible light. It is predominant in the light that the sun emits at noon, when the sky is clear. Sunlight is, by far, the largest source of blue light in our environment. The screens of our computers, phones, and other digital devices are also sources of blue light.
UV Light Blocking
UV light is generally defined as invisible. UV light has much higher energy levels than visible light. Exposure to UV light can cause changes in the skin, leading to suntan, sunburn, wrinkles, and potentially skin cancer.
WHAT IS UV LIGHT?
The cornea and lens of the adult human eye are quite efficient at blocking UV radiation and keeping it from reaching the retina. However, UV light damages the skin and front structures of the eye. Prolonged exposure to UV light is linked to pterygium, photokeratitis (snow blindness), cataracts, and other eye disorders. Neochromes lenses block 100% of UVA and UVB rays (in the violet light range).
DO YOU HAVE SENSITIVITY TO LIGHT?
Neochromes is the perfect lens for people suffering from symptoms related to light sensitivity.
MOST FREQUENT SYMPTOMS OF OCULAR SENSITIVITY:
- → Continuous itching in the eyes
- → Need to squint or close your eyes in bright light
- → Slow adaptation to changes in light
- → Excessive tearing
- → Eye discomfort with the light from the screen of your mobile device
- → Redness or inflammation of the eyes
The Key
Photochromic molecules have, under normal conditions, a folded shape that makes them transparent. When absorbing ultraviolet light, their shape changes, the molecular structure opens and absorbs visible light. The two forms of the photochromic molecule - open and closed - exist in balance with a bond that’s continuously broken and rebuilt.
The photochromic molecule constantly switches between its transparent and dark states. If the lens is exposed to significant levels of UV light, most of the molecules will be in the open state, darkening the lenses. In the absence of UV light, the molecules will remain closed, resulting in clear lenses.
Neochromes Behavior
TEMPERATURE AND ITS EFFECT ON PHOTOCHROMIC TECHNOLOGY
Any photochromic lens is affected by temperature. In cold temperatures, photochromic lenses darken more and take longer to fade back. In warmer temperatures, the lenses don't darken as much and fade back more quickly. This is a characteristic of the state of balance in a photochromic system.
