Visual Impairment | Low Vision | Difficulty Seeing
AZ, Phoenix, Gilbert, Mesa, Tempe, Arizona
Low vision exists when any condition affecting the eye and visual system challenges a patient, reduces their vision, and limits their ability to perform necessary daily tasks and also enjoy those things that bring quality and pleasure to their lives.
When ordinary eyeglasses, contact lenses, surgery or intraocular implants cannot provide sharp vision, an individual is said to have low vision. Macular degeneration, diabetic retinopathy, glaucoma, and retinitis pigmentosa, along with many other eye diseases, are causes of visual impairment or low vision. People with decreased vision still have useful vision and should seek out the care of an eye doctor who specializes in vision rehabilitation.
Low vision may present itself as: a loss of central vision, loss of peripheral or side vision, blurred vision, extreme sensitivity to light, and night blindness. Patients frequently cannot read, identify the faces of family and friends, play cards, watch TV, use a computer, drive a car, see the food on their plates or their faces in a mirror.

Low Vision Lighting | Tasks Lamps | Photophobia
AZ, Gilbert, Chandler, Phoenix, Mesa, Tempe, Arizona
While many low vision patients experience photophobia or are very glare sensitive, they also require a tremendous amount of light to perform tasks with their low vision aids. The correct use of lighting is just as important as using the correct low vision aid. If a person is able to read outside with their back to the sun but cannot read in their home, they most likely do not have the correct lighting.
Viewfinder Low Vision Resource Center has a large selection of reading and task lamps. We also have a selection of portable lamps that can be taken to restaurants, card games and other activities. The best type of lamp is a goose-neck lamp that directs the light directly over the shoulder while reading. This will give enough light on the reading material but will not cause glare. A lamp that is placed to the side, or on a side table, may be a source of glare and shadows. Good direct task light is also important for seeing food while eating, working in the shop or in the kitchen. Have portable lights or flashlights to help with dark areas in the home.
Light Sensitivity | Glare Control | Photophobia
Arizona, Mesa, Tempe, Chandler, Phoenix, Glendale AZ
Photophobia or extreme sensitivity to light and glare can be a severe problem for many low vision patients. Many eye diseases can create intraocular light scatter which 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. Glare control can be a problem both indoors and outdoors.
Many low vision patients complain of intense light sensitivity and hazy vision when visual function is impaired by glare and loss of contrast. Sensitivity to light and glare can be reduced with a number of prescribed low vision aids. Special glasses and tints will also increase contrast sense which will also increase visual acuity.
There are a large variety of tints or filters with varying degrees of light transmission and contrast enhancement to reduce the sensitivity to light and glare. To read more about these products click here
Bioptic Telescope | Driving with Visual Impairment | Ability to Drive
Arizona, Chandler, Phoenix, Tempe, Mesa, AZ
The ability to drive is a privilege that many of us take for granted. Driving affords us extended freedom of mobility and greatly enhances our quality of life. Visually impaired individuals can feel restricted and isolated when faced with losing their ability to drive.
A Bioptic Telescope can restore driving freedom to visually impaired adults. Arizona is one of 41 states that will grant a driver’s license to some visually impaired people when they drive using a bioptic telescope. Driving with a visual impairment while using bioptic telescopes is a very important personal decision that should be made collaboratively by the individual, the low vision eye specialist, and the motor vehicle department. To find out if you are a good candidate for driving with a bioptic device, make an appointment at ViewFinder Low Vision Center by clicking here.
