CPF (Corning) GlareControl Lenses
CPF (Corning) Glare Control Lenses for Medical Filter Applications
Glare Control Lenses do some pretty amazing things that may help patients who have light-sensitive eyes see better. These lenses have proven beneficial for patients that have various stages of Macular Degeneration, as well as other medical conditions that affect sight.
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.
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: Glare Control Lenses shield
from 100% of potentially harmful UV rays.
Durable, Scratch Resistant Glass: Glare Control's
filtering characteristics and photochromic properties will not change or wear out. Ever.
In contrast to glass,
plastic lenses cannot provide the same spectral control as Glare Control
lenses. Plastic lenses also scratch easily and can fade over time.
A Range of Filter and Frame Options:
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.
People with severe light
sensitivity are most likely to benefit from Glare Control Lenses --
especially when it's caused by these and other conditions: cataracts,
macular degeneration, glaucoma, diabetic retinopathy and
A lightly colored lens comfortably enhances contrast and helps
control glare indoors. For reading, watching television and coping with fluorescent lights in offices and supermarkets. Frequently chosen for:
Medium-range filter provides moderate blue light filtering while
permitting longer wavelengths of lower energy light to pass through.
Especially helpful for individuals with:
* Optic Atrophy
Orange-amber lens darkens to brown in sunlight, giving individuals
better visual function and reduced glare. Frequently chosen by people
The original GlareControl lens relieves the stress of intense
sensitivity to light and poor dark adaptation. Lens color varies from

A very specialized medical lens for persons with extraordinary light sensitivity from conditions such as: *Achromatopsia
Effects of Glare Control Lenses
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
Cautions and Warnings
