NoIR Fit-Over Anti-Glare UV Shield Red 58% VLT

Description

Red eyewear filters with 58% light transmission

These fit-over sunglasses from NoIR are a clear winner for anyone who needs to shield their eyes from glare. The Red-coloured filter allows just 58% light transmission, cutting glare and increasing contrast for the user. Offering 100% ultraviolet (UV) and blue blocker protection, they can also offer eye relief from bright rays in outdoor sports, as well as some Low Vision conditions.

Designed to fit over normal glasses

Ideal for spectacle wearers these fit-over shields have been primarily designed to fit over normal glasses. They offer a far more affordable and practical solution than having to purchased expensive special prescription sunglasses. With all-round filtering, including side shields and top brow, they give light-sensitive eyes some relief from both the sun’s rays and glare from other lighting sources.

Visible light transmission

With a VLT of 58%, these shields limit the amount of light that gets through to the eye. VLT – Visible Light Transmission – indicates the percentage of the visible spectrum (380 to 720nm) that transmits through the lens, balanced with the sensitivity of the human eye. A VLT of 65% down to 35% would broadly be regarded as high enough to be useful in most environments. Filters with a VLT in the 20s or below allow much less light to get through, and can be helpful for people with different eye conditions. For general safety please note that they should be only be used in areas where working light is very bright or well-illuminated.

NoIR –affordable protective eyewear since 1972

For more than 50 years, NoIR eyewear has led the way for the professional Low Vision community. In the early 1970s, UV blocking sunglasses were common, but Infra-red protection was something new. The ‘No InfraRed’ – or ‘NoIR’ – glasses found a niche in the market for filters that could relieve eye fatigue by reducing or absorbing the heat energy of the sun

Promoting eye safety, comfort and affordability, NoIR eyewear helps shield eyes from glare, also enhancing contrast. Different coloured filters enable people with light-sensitive eye discomfort to live more mobile and independent lives. NoIR UV shields make it easier for user to better protect themselves from the impact of ambient light.

Ultraviolet absorption and protection against glare

All NoIR filters absorb UV radiation to 400nm. Many lenses also block blue light, which helps protect the retina from the high-energy wavelengths thought to contribute to the degenerative process culminating in macular degeneration. NoIR filters prevent 99% of all glare-causing high-energy short wavelengths from reaching the eye. By absorbing the energy from the sun’s heat, they help cut infrared wavelengths and effectively ‘cool’ the light intensity so that wearers enjoy a more comfortable and soothing viewing experience.
