Embrace the light
NOW'S THE TIME TO MAKE THE CHANGE
Neochromes state-of-the-art lens technology offers wearers maximum freedom, comfort and protection. Photochromic molecules react quickly to changes of light, ensuring an exceptional visual experience in any situation.
WHAT IS NEOCHROMES?
Neochromes is a line of state-of-the-art photochromic lenses offering wearers optimal vision and maximum comfort in any light, without needing to change glasses.
Neochromes lenses adapt instantly to changes of light, darkening in seconds and returning to clear again in record time. They provide optimal eye protection against harmful UV and UVB rays, as well as reducing eye fatigue for maximum comfort. Their attractive colors, aesthetic appearance and fast performance ensure wearers feel perfectly comfortable indoors or outdoors, in sun or shade. They represent the ultimate in hassle-free vision.
Neochromes state-of-the-art technology makes now the perfect time to change to photochromic lenses. For clear and comfortable vision, without worrying about changes of lighting or the harmful effects of UV rays from the sun.

NEOCHROMES LENSES ARE
SO NATURAL THAT THE WEARER
WILL FORGET THEY ARE WEARING THEM
BLUE LIGHT /
WHAT IS BLUE LIGHT?
Blue light is the portion of the visible light spectrum with the highest energy. 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.
NEOCHROMES LENSES OFFER ENHANCED PROTECTION AGAINST THESE WAVELENGTHS OF LIGHT, TO HELP PREVENT EYE FATIGUE
UV LIGHT /
WHAT IS UV LIGHT?
UV light is invisible, with 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. 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
Technology and performance have come together in Neochromes to deliver a better experience for wearers and create new market opportunities.
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 LENSES´ CUTTING-EDGE TECHNOLOGY ENSURES MAXIMUM PERFORMANCE IN ANY LIGHT CONDITIONS
Before UV light exposure, the lens is in its most transparent state.
When the lens is first exposed to UV light, the photochromic molecules begin to change from clear to dark.
Lenses are at peak activation. Light transmission, activated color, and color uniformity can be assessed at this state.
Fast fade-back is critical. It begins when UV light does not fall on the lens any longer. The shorter the fade-back, the more comfortable and functional the lens is to the wearer.
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.
The performance of Neochromes lenses also adjusts to the ambient temperature, with faster fade-back times in warm conditions.

HOW TO ANALYZE IT
KINETICS CHARTS SHOW FOUR PHASES OF PHOTOCHROMIC LENS ACTIVATION
1. The clear stage
2. The darkening stage
3. The dark stage
4. The fade-back stage
The percentage transmission (or transmittance) is on the vertical axis. On the horizontal one, we move over time from the initial transparent state to the UV exposure, the subsequent darkening and finally, the removal of UV light and the return of the lens to the transparent state.
As seen in the kinetic graph, at room temperature and outdoors, Neochromes lenses have a clear appearance with 85% light transmission, similar to clear high index lenses. Light transmission is significantly increased with the application of high-quality, low reflectance anti-reflective coating.
In a photochromic lens, darkening is always much faster than lightening. The darkening speed is the time required for the lens to pass from the transparent state to its mid-transmittance point.
The fade-back speed considers the time required for the lens to pass from the activated state to the mid-transmittance point.
