of Blue Light
Light plays an essential role in everyday life.
Light 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 light can also be the cause of premature eye ageing.
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).
Blue-violet light increases the risk of retinal damage.
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 AMD.
Wearing lenses with blue-violet light protection helps shield your eyes from harmful blue light. As well as blue-violet protection, you can also opt for lenses with UV protection as well.
Some blue light protection lenses filter all blue light including blue-turqoise light. Blue-torquise light is essential to your well-being as it contributes to your sleep cycle, pupillary reflex, energy and more.
