NoIR Fit-Over Sunglasses with UV Shield & Grey Filter (28% VLT)

Description

Fit over specs with Grey lens filters

Large fit-over sunglasses from NoIR with grey-coloured lenses, which filter out all but 28% of ambient light transmission. Offering 100% ultraviolet protection, this filter colour is a popular all-rounder for reducing glare and increasing contrast. Can also be helpful for some Low Vision conditions, including Cataract and Glaucoma.

Universal fit, with or without spectacles

This frame will fit over normal prescription glasses or can be worn directly on the face as normal sunglasses. With all-round side shields and a top brow, they give light-sensitive eyes extra protection from the bright sun or harsh indoor lighting. Now there’s no need to squint, or feel your eyes water because they are sensitive to the ambient light. Ultra-light, they also feature extendable curved temples and have a soft, non-slip texture that makes them comfortable to wear.

Just 28% light transmission

The grey lenses allow just 28% Visible Light Transmission (VLT). This is the percentage of the visible spectrum (380 to 720nm) that transits through the lens, balanced with the sensitivity of the human eye. In broad terms a VLT of 65% down to 35% is normally high enough to be useful in most environments. Lenses with a VLT in the 20s or below allow much less light to get through the lens. They can be helpful for people with certain 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

The NoIR filter system has been championed by the professional Low Vision community for more than fifty years. When NoIR began, UV blocking sunglasses were common, but Infra-red protection was something new. The ‘No InfraRed’ or ‘NoIR’ glasses quickly established a market niche, offering relief from eye fatigue by reducing the heat energy of the sun, and serving a ready medical audience amongst the visually impaired.

Promoting eye safety and comfort, the company makes advanced but affordable eyewear that shields eyes from glare and helps increases contrast. Coloured lens filters reduce visible light transmission so that people who have light-sensitive eye discomfort can live more independent and mobile lives. Available in wraparound and fit-over styles, NoIR sunglasses and UV shields help people with visual impairments to better manage and control ambient light.

Ultraviolet absorption and protection against glare

All NoIR filters absorb UV radiation to 400nm. Many lenses also block blue light, thereby help guarding the retina from high-energy wavelengths that may 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.
