CPF (Corning) GlareControl Lenses for Medical Filter Applications

GlareControl Lenses do some pretty amazing things that may help patients who have light-sensitive eyes see better.

Blue Light Absorption: Uniform and precise filtering shields eyes from short wavelength, high energy blue light that can cause discomfort to light-sensitive eyes, contribute to glare and loss of contrast, and reduce effective vision.

Photochromic Comfort: Ground and polished photochromic glass lenses automatically darken on bright sunny days, overcast or hazy days. And they lighten indoors when a television or reading lamp may be the only available light.

Effective UV Blockage: GlareControl Lenses shield from 100% of potentially harmful UV rays.

Durable, Scratch Resistant Glass: GlareControl's filtering characteristics and photochromic properties will not change or wear out. Ever.

State-of-the-Art Performance: In contrast to glass, plastic lenses cannot provide the same spectral control as GlareControl lenses. Plastic lenses also scratch easily and can fade over time.

A Range of Filter and Frame Options: Choose from five graduated filter levels, plus the NEW CPF® GlareCutterT lens for people with beginning to moderate light sensitivity. Single-vision, multifocal, special or plano lenses. Select any ophthalmic frame, or choose one of ours -- side shields and aviator frames. Or choose lightweight clip-ons to fit over regular glasses.

Medical Applications: People with severe light sensitivity are most likely to benefit from GlareControl Lenses -- especially when it's caused by these and other conditions: cataracts, macular degeneration, glaucoma, diabetic retinopathy and retinitis pigmentosa.

Effects of GlareControl Lenses

CPF (Corning) GlareControl Lenses block 99% of UVA wavelengths.

The blue light portion of the visible spectrum is most likely to scatter in the eye, causing discomfort and hazy illusion.

CPF (Corning) GlareControl Lenses attenuate 98% of high-energy blue light, with exception of CPF 450, which is 96% of high-energy blue light.

The CPF GlareCutter product is not described in terms of a specific wavelength cut-off. Its purpose is to serve patients who are beginning to experience light sensitivity problems outdoors. These patients don't require as much blue light attenuation as traditional CPF products provide. This additional blue light leakage allows the GlareCutter to be more cosmetically pleasing with minimal color distortion.

Cautions and Warnings

CPF (Corning) GlareControl lenses are chemically tempered to meet FDA impact resistance requirements, but they are NOT unbreakable or shatterproof.

GlareControl lenses do not pass some ANSI traffic signal requirements.

Check before driving... For safety's sake, your patients should be sure they can distinguish the colors in traffic signals before driving. GlareControl lenses, like any strongly tinted lenses, should not be worn for night driving. CPF® 550 and 550XD lenses are not recommended for any driving, night or day.
