Low Vision Lens Filters
To address the needs of people with various visual impairments (such as light sensitivity), we offer a full range of Cocoons featuring special absorptive filters developed specifically for Low Vision applications. We strongly recommend that you consult your eye care professional or physician when selecting the Low Vision UV absorptive filter that will best suit your particular eye condition or visual impairment.
Low Vision Cocoons feature specially formulated absorptive filters that are available in four specific tints and are proven to increase visual acuity when used in conjunction with various types of vision related impairments. Each of the patented frame sizes/styles are designed to comfortably and securely fit over prescription glasses, but can also be worn equally as well on their own.
