V radiation is always present. All year round, all day, in winter and summer, in sunny and even overcast conditions. UV rays have some positive effects on us, for example it triggers Vitamin D production.
Unfortunately, prolonged UV exposure also poses some serious health risks.
Most of us know that UV rays can damage the skin, but UV exposure can also be harmful to the eyes and the surrounding skin. To protect the skin, we wear sunscreen but we really don’t have a lot of options when it comes to
protecting our eyes against harmful UV rays.
UV radiation is subdivided into three bands:
- UVA (also called UV near) extends from 315 to 400 nm
and are the longest waves that can penetrate deep into
the skin’s surface, re-leasing free radicals and causing
- UVB (middle UV) extends from 280 to 315 nm. These
longer waves reach the skin’s surface and can cause
surface tanning, burning and signs of ageing.
- UVC (far UV) extends from 100 to 280 nm and are

ZEISS always push the boundaries – whether they're providing vision solutions for spectacle wearers or supplying eye care professionals with state-of-the-art technology and instruments. Although the ophthalmic world is well aware of the need for UV protection, it’s still not a key focus area in the industry. ZEISS is raising its standard of eye care.
All ZEISS clear plastic lenses now provide protection against UV rays up to 400 nm, the UV hazard as defined by the International Commission on Non-Ionizing Radiation Protection (ICNIRP) and the World Health Organization (WHO). 40% of UV radiation in daylight occurs between 380 to 400nm. These longer UV waves penetrate more deeply into our skin and ocular tissue, making them a potential risk factor for various eye health issues.
Up until now most clear lenses fall short of fully protecting a person's eyes from UV radiation up to 400 nm. Are your spectacle lenses protecting your eyes?Your eyes are precious - protect them with ZEISS UV Protect clear or tinted lenses.
At an awards ceremony held in London's ExCel in January 2019 ZEISS UV Protect Technology lenses were awarded Product of the Year by the Association of Optical Practitioners.
