BPI^® Diamond Dye™ outlasts all other UV dyes
No more boil-overs! No more globs in your tint tank! BPI® UV Diamond Dye™ 400nm is virtually clear. It will not build-up in the bottom of your tank. In fact, it will not wear out because of the amount of time in the tint tank. Diamond Dye™ 400nm was the first UV dye and has exhaustive laboratory testing and clinical use. Millions of lenses each year are protected by UV Diamond Dye™ 400nm. BPI® UV Diamond Dye™ 400nm is the ideal UV dye for those labs that have low volume UV treatments. You can expect well over 100 pairs from a single bottle. Many labs have experienced up to three months of use from a single bottle.

Protection never fades
It is the only UV dye that will NOT fade. In fact, the longer it is exposed to ultraviolet light, the more UV light it absorbs due to its active crystal matrix.

UV and scratch protection
UV Diamond Dye™ 400nm has the only active crystal molecular matrix that penetrates deep into the lens. The density and hardness of the crystal matrix will reduce the number of scratches.

No more yellow lenses
UV Diamond Dye™ 400nm will never yellow a lens! In fact, it is the only UV dye recommended by many manufacturers of hard coated lenses.

BPI^® UV Only™
During the BPI® UV-Only™ treatment process, the lens is cured and the dye becomes part of the lens matrix. Protection will last for the life of the lens. The process may take as little as 5 minutes and the lenses are almost clear after treatment. They may then be tinted if desired. You can UV protect your patient’s lenses in only a few minutes with any BPI® lens tinting system. BPI® UV Only™ will help prevent cataracts, macular and corneal edema and senile macular degeneration due to ultraviolet light.

BPI^® UV Crystal Clear™
After five years of exhaustive research and testing, Dr. Wertheim and the R&D team at BPI® invented a new UV dye. BPI® UV Crystal Clear™. It never boils over! BPI® Crystal Clear™ lasts up to three months in your dye tank and provides protection to hundreds of lenses in about two minutes. This new UV dye fades less than 2% in five years, it is crystal clear in your tinting system and meets USA ANSI Z80.3 standards. Don’t risk the health and vision of your patients, insist on BPI® UV protection. If you don’t tint you own lenses, BPI® will provide the name of the nearest lab that can treat your lenses with BPI® tints and UV protection.
