Sunlight is the most significant source of UV radiation and can damage various ocular tissues:
- Surface of the eye - can be subject to snow blindness
- Lenses - can develop cataracts
- Retina – can develop solar maculopathy and macular degeneration
The UV light spectrum covers wavelengths from 100 nanometers to 400 nanometers. UV light consists of UV-A light, which leads to skin tanning, but also skin aging. UV-B light can lead to sunburn and skin cancer. The good news is that UV-C light, the most dangerous kind, is almost completely blocked by the ozone layer.
What most people don’t know: Eyes can also get sunburned. The cornea and the conjunctiva are most affected. The highest risk is always when sunlight is heavily reflected, something that can occur in a snow-covered landscape or when spending time near water.
With the right glasses, everyone can protect their eyes from dangerous UV rays. ZEISS has these solutions to protect your eyes:
Tints and Gradients – All provide UV protection by absorbing at least 99% of UV rays or light rays up to 400 nm. Solid tints are uniform throughout the lens, while gradients are darker in the top and lighter on the bottom to accommodate reading.
Polarized Lenses - They block diffused light; for example, light reflected off water surfaces or wet pavement. They are particularly useful for driving and fishing.
ZEISS DuraVision Mirrors - They reduce the quantity of light reaching the eye, and offer full UV 400 protection when added to tinted or polarized lenses.
ZEISS Sport Lenses – Wrapped sunglasses protect the eyes from light entering from the sides.
ZEISS PhotoFusion self-tinting lenses: They darken automatically when it is bright, providing full UV 400 protection, and lighten indoors or at night.
Remember to protect your eyes each day from the sun’s harmful UV rays, just as you protect your skin.
ZEISS PhotoFusion and sunlenses provide you with full UV 400 protection so you can enjoy the outdoors.
