New! From Essilor: Crizal Prevencia
Light plays an essential role in everyday life. It is fundamental for vision. It is needed for perception of the surrounding world: shapes, details and colours. Good Blue light (blue-turquoise part) is essential for overall well-being. It is neccesary for regulation of the sleep/wake cycles, mood and cognitive performances.
But certain bands of blue light can also be the cause of premature eye ageing. Ultraviolet (UV) light is already well known and all Crizal lenses include UV protection as standard. But harmful blue-violet light was recently identified as being harmful to retinal cells. Causing long-term damage to our eyes, it can accelerate the onset of age related Macular Degeneration (AMD).
Cumulative exposure to blue-violet light has a double effect:
- · It increases the production of lipofuscin, a metabolic waste material that accumulates in retinal cells with age. It is commonly known as an "age marker" that may be found in other organs.
- · It activates lipufuscin phototoxic components, causing retinal cell death. The accumulation of lipofuscin in retinal cells can contribute to the deposition of drusens in AM
Preventing over-exposure of blue-violet light may decrease the death of retinal cells
UV and Blue-Violet light is present everywhere - Outdoors: Whatever the weather UV and blue-violet light is present (sunny, cloudy, rainy, etc.) and Indoors: Wherever the place blue-violet light is transmitted by low energy light bulbs and most modern digital devices, including tablets, smartphones and computers.
