EnChroma Inc. said in a press release that the Lx Eyewear device series could help people with low vision and age-related vision impairments.
Each of the four lens categories in the series filter blue light and offer 100% UV protection. Transmission decreases in each category from Category 1 (80%) to Category 4 (3%) to accommodate different lighting conditions and higher glare reduction needs.
People with severe glare sensitivity often select different lens tint options through trial and error, with the trade-off that darker lenses reduce glare but can also eliminate important visual information, while lighter lenses enhance the edges of objects but do not cut glare, according to the release.
“EnChroma Lx Lens Technology features a unique spectral filter that reduces the intensity of white light while transmitting colors up to two times brighter than an average lens,” Tony Dykes, EnChroma co-founder and CEO, said in the release.
The lenses may benefit people who have cataracts, corneal damage, optic neuropathy, age-related macular degeneration, glaucoma and other visual disorders associated with glare sensitivity and reduced color vision, according to the release.
The company said it worked with low vision optometrists and patients with serious eye conditions to develop the lenses.
"EnChroma Lx glasses augment what little vision I have, that I didn’t think I still had, and helps me regain pieces of information I couldn’t perceive before, which reduces my reliance on tactile and echo perception,” Blair Wong, ABOM, BS, chair of the eye health technology department at Benjamin Franklin Institute of Technology and associate professor at the New England College of Optometry, said in the release. Wong is a licensed optician and has late-stage retinitis pigmentosa.
