FL-41 is a generic tint that has been proven to help with conditions associated with light sensitivity. We are the original retailer of therapeutic FL-41 tinted lenses online. Our proprietary Spectrashield FL-41 tint looks distinctly different than the generic version. Our blend has been fine-tuned over 20 years.
It successfully blocks the distressing portion of the light spectrum, which bothers light sensitive people and causes cumulative eye damage over a lifetime. To accommodate as many people as possible, we also offer some variant lenses. Our outdoor version of the tint has the greatest filtration power. We are the exclusive manufacturer of FL-41 tinted transitions and 365-day Soft Contact Lenses. All of our lenses block UVA and UVB light. For complete protection against reflected UV light, add our Premium Multipurpose Coating.
