Glare Control
 |
Photophobia
or extreme sensitivity to light and glare can be a severe problem
for many low vision patients. Early stages of macular degeneration
and generalized vitreous or lens opacities create intraocular light
scatter that can significantly reduce effective vision. The eyes become
hypersensitive to what the normal eye sees only as moderate glare.
The shorter wavelength, high-energy part of the visible spectrum dominates daylight and is a |
| contributor to glare. Patients complain of intense light sensitivity and hazy vision. Visual function is impaired by glare and loss of contrast. To effectively improve a persons vision, problems with glare need to be addressed when glasses or other low vision ads are prescribed. | |

There are a large variety of suntints with varying degrees of light transmission. The sunglasses can be pre-made to be worn alone or over the patient's current eyeglasses or they can be custom-made with the patients prescription. Polaroid lenses, Corning Glare Control Lenses, ultra-violet (UV) coatings, anti-reflective coatings and pinhole contact lenses will all help a patient become more comfortable both indoors and outdoors. The light sensitive patient should also consider wearing frames with side shields along with hats and visors. |
