Protection from harmful light

THE RISK
OF UV

The risk of damage to the eyes from UV light has increased due to ozone depletion in the atmosphere.

Your eyes can become irritated if not protected. You may also put yourself at increased risk of premature ageing of the eyes and other diseases such as cataracts and skin cancer on the eyelids. Our eyes are exposed to UV every day, whatever the conditions. Up to 40% of UV exposure occurs outside of direct sunlight, and it comes from reflections off buildings, glass, water, the sky, the ground, and even off the back of the surface of your lens if they are not treated with UV protection.

Solution - Wearing lenses with UV protection helps shield your eyes from ultra-violet radiation. As well as sunglasses, you can also opt for clear lenses which also protect against UV. Some lenses offer a higher level of protection than others. Significant UV exposure for spectacle wearers comes from the rear lens surface. Look for a lens with a high Eye-Sun Protection Factor which protects from both the front and rear surface of the lens.

THE RISK
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 necessary 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.

Solution - 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-turquoise light. Blue-turquoise light is essential to your well-being as it contributes to your sleep cycle, pupillary reflex, energy and more.
