BPI® Diamond Dye 460/510nm™

BPI Diamond 460/510 is a new addition to the therapeutic tint line-up of BPI Blue Filter Vision 450, Diamond Dye 500/550 and BPI Diamond Dye 540. BPI Diamond Dye 460/510 is a cut-off tint which blocks light of wavelength shorter than 460nm when tinted light and values up to 510nm when tinted more darkly.

This tint blocks violet/blue in this spectral range very well, and should be helpful in protecting the eye from these light colors, which have been implicated with macular degeneration. This tint does not inhibit seeing the traffic signal colors - it passes the European traffic signal recognition requirements, so it can be used while driving.

Since the blue sky is darkened to a gray green when viewed through this tint, sport shooting enthusiasts will find this tint an aid in spotting skeet targets against the sky.

 

 

 

BPI® Chroma Pink

A brilliant fashion pink in liquid form, The unique chemical structure of our tints makes them more stable and reduces tinting time. The tint molecules bond to the lens and become part of the lens structure. The lens cures in the tinting process and has a more scratch resistant surface. Choose from more than 188 BPI® colors. BPI® Tints are available in 3 ounce (88 ml) plastic bottles and money saving six-packs. Each 3 ounce bottle makes one quart (946 ml) of solution and tints hundreds of lenses. Some colors are available in quart (946 ml) bottles. BPI® tints are now also available as Pills®.

 

BPI® Chroma Gray

A fashionable blue gray only available in pill form, The Pill is a convenient and economical way to tint with the most common colors. Storage life is indefinite as long as the packaging remains intact. It takes up less shelf space than standard dye bottles and is less expensive to ship.

BPI pill tints come in an envelope of two separately packaged pills. Two pills in a quart of water provide comparable tinting strength to a single bottle of standard tint. One pill is just right for tinting in a one-pint Mini-Tank..

 

BPI® H2O Neutralizer II

New and even greener / safer chemical formulation,  BPI H2O Neutralizer II is a water-based, lab safe neutralizer that removes dye from lenses made from coated and uncoated CR-39 monomer, polycarbonate and high-index materials without any color shifting. H2O Neutralizer II, is super concentrated to save on shipping costs.

BPI® UV & Blue Light Analyzer

Recently, the blue/violet wavelengths between 400nm and 500nm have been implicated in the development of macular degeneration. BPI® has developed a simple meter that is designed to check the transmittance of lenses for these wavelengths and provide a figure of merit to use in comparing and producing lenses that protect patients from radiations in this wavelength range.

The BPI® UV & Blue Light Analyzer uses LED light sources centered at 400nm, 430nm, 470nm and 505nm to evaluate lens transmission in these regions. The transmission percentage at each range is displayed along with the Wertheim Protection Factor, a figure of merit based on a comparison of the lens’ photopic transmission with its blocking ability for high-energy (blue/violet) wavelengths.

The meter also has caution indicating LEDs which indicate if the lens transmission is higher than that which would be provided by a linear drop in transmission with wavelength from its tV value down to zero in the UVA.

Air (no lens) lights all caution LEDs and has a Wertheim Protection Factor of “0”. A lens with high luminous transmission but minimal high energy blue/violet transmission such as BPI® Total Day has a Wertheim Protection Factor of “43”.

BPI® RGB Spectrometer™

The BPI® RGB Spectrometer is an invaluable aid for:
matching the colors of tinted lenses or filters. It may also be used to check CIE or (L*,a*,b*) color coordinates. It also checks the upper UVA (350nm-400nm) transmission and provides filter level information. More precision is available from the BPI® Spectrometer. For color matching the RGB Spectrometer should be used with a personal computer running the Companion Program. The system power pack requires 115 Volts 50/60 Hz and is fuse protected by a 1 Amp, 250 V glass fuse. Components are UL and CSA recognized.

BPI® Blue Light Filter Vision Tester™

Recently there has been increased interest in protecting the eye from harmful violet and blue light. Anti reflective coatings formulas have been altered to be less effective in this spectral region, reflecting back about 20 percent of the light there rather than allowing its full passage.
BPI® has recognized the need to protect the eye from short wavelength light for many years. Our Blue Barrier / Filter-Vision / Designed Spectrum 450, 500 and 540 absorptive tints were available in the last century. These tints absorb all (not just reflecting back 20%) of the harmful light of wavelengths shorter than 450nm, 500nm and 540nm, respectively, including UV light.
Blue/Violet light in general is a problem for the eye since it scatters more than other wavelengths, causing unwanted light “noise” within the eye. Reducing the spectral range of light entering the eye lens also cuts down on lens chromatic aberration. Age-related macular degeneration problems, which may be exacerbated by blue/violet light, have been mentioned more recently by Dr. Janet Sparrow, et al. in Optom Vis Sci. Jun 2011; 88(6): 759–765.
The BPI® Blue Light Filter Vision Tester is a blue/violet light source that demonstrates the effectiveness of a blue/violet light blocking lens. The intense blue light beams produced by the source are greatly attenuated by some lenses and the effect is readily observed when the lenses are placed between the source and your eye.

BPI® Lens Color Filter Selector

BPI® has introduced a new computer program, the BPI® Lens Color Selector. This program enables the user to alter the color of images to see how they would appear if seen through tinted lenses. The user may change that color until the image is rendered as the user desires. The program will then determine which standard tint colors most closely approximate that which they selected.

Images supplied are nature scenes, special purpose (skeet against various backgrounds, for example), Ishihara color blindness test images, other therapeutic related images and much more. The user may upload images of interest to them, to see what tinted lens color would be beneficial in that situation.

The program will also assist you in color matching of tinted lenses to find standard colors which are similar to them.

BPI® Black High Index Lens Holder™

The BPI® High Index lens holder comes from themakers of the original and most popular BPI® lens holders used in more than 40,000 labs around the world.

It has sometimes been observed that when tinting High Index lenses a dark blotch is left on the lens near the location of the lens holder’s metal rods. This blotch is not present when the metal rods are replaced with plastic rods.

This lens holder tolerates the same tinting conditions as the standard metal rod lens holder. Choose from 23 other BPI® lens holder models.

The new black color high index lens holder avoids discoloration during tinting.

Attention 3D printer users!

We have noticed that the PLA plastic resin used in many 3D printers is easily tintable using BPI Molecular Catalytic Tints (available in 180 different colors). This makes it easy to create plastic parts in your 3D printer using only white or clear plastic and then tint them to your favorite colors, saving the trouble of changing plastic source in the printer. ABS plastic may be less suitable for tinting.

Note that BPI® tints are not FDA approved for food and beverage use, although they do not contain heavy metals or phthalates. These tints belong to the same family as textile dyes used in clothing. MSDS information available on this website.

We are often asked how to tint or color clear plastic parts. BPI® tints have been used to color many clear plastics, such as Acrylic (Plexiglas®), Polycarbonate (Lexan®), CR-39® (plastic eyeglass lens material), Nylon, Fiberglass, Mylar, Cellulose Acetate Butyrate, Vinyl, some Silicones, Epoxy, PET, PETE and many others. We have made special tints for some of these materials, but many of them can be colored using any of our nearly 200 standard BPI® Molecular Catalytic™ Tints. Usually, these tints must be heated before the color will enter the plastic part and the color obtained depends on the type of plastic (or the coating on the plastic!) and the temperature of tinting. The results you would get for your plastic parts can best be determined by testing them with a heated multicomponent tint such as BPI® Molecular Catalytic™ Black. Let us know what plastics you have tried and what results you got!

BPI® is the world’s largest manufacturer of optical tints that are used by opticians, optometrists and ophthalmologists in tinting, dying, or otherwise coloring clear plastic – especially optical sunglass lenses. BPI® also produces lines of therapeutic tints providing UV protection and aiding with problems such as blepharospasms, headaches, retinitis pigmentosa, color blindness, corneal dystrophys, macular degeneration, retinal damage and dyslexia. BPI® has specialty tints such as EVA for viewing computer monitors and Solar Dyes for the finest sunglasses. BPI® also manufactures laboratory equipment such as tinting instruments, photometers, ultrasonic cleaners, edgers (for edging lenses), gradient lensors (for producing gradation of tint on lenses) and ovens for heat and chemical tempering of glass lenses for safety glasses and eyewear. BPI® supports all optical lens and sunglass manufacturers and optical laboratories.
