The Amazon Echo would be perfect for her. Did you find something to help the blind use the telephone? Hi Bettie, thanks for writing! Hi Bettie — When my father lost his central vision to macular degeneration I bought him a Jitterbug cell phone. With some training, he could make calls, which was amazing because my father, who passed away 9 years ago, was afraid of anything technical.
The basic flip phone model was best for him because he could feel around the large buttons on the dialer. The Jitterbug is much more than a phone. It comes with services that allow you to have an operator dial for you, or locate you and send help, or remind you of when to take medications, and a lot more.

I am not a representative for Jitterbug, so I am not trying to sell you one. It might work for your friend; it might not. If she understands how to work a cell phone, she could probably use it. The plans are flexible and affordable. And you can probably buy one used on eBay or Amazon. Thanks for these suggestions. Big Letter Bananagram is arriving this weekend. Your suggestions help my 95 yr. I find this dialogue so helpful! I am trying to stay self sufficient. Blue and violet light is extreamly painful. It is also important to determine an intermediate correction, whether it is looking at the computer screen, digital pad, or portable telephone.
A visual field analysis is one of the most important tests of visual function. The use of static and automated perimetry, as well as integrating new technology such as microperimetry with the optical coherence tomographer, helps establish the extent of the visual field loss and the ability to travel independently. But visual field analysis will also help to determine whether persons affected from conditions such as stroke or a tumor may benefit from the application of optical solutions, including the use of prisms for mobility.
The low vision evaluation also determines the appropriate low vision devices for examples see Bakker, to help achieve the patient objectives. These include the prescription of a very strong reading lens also known as high plus or microscopic reading lenses and hand and stand magnifiers.

The recommendation for hand and stand magnifiers magnifiers that sit on the page has changed with an understanding that enhancement of contrast conditions requires the use of good task lighting. One of the best new light sources includes the use of xenon. Halogen is too bright and hot, and constitutes a burn and fire hazard Government of Western Australia Fire and Rescue Service, The patient with a distance objective such as independent travel may benefit from a hand-held or spectacle-mounted telescopic.
But newer and future technologies, such as a head-borne computer with GPS, may help to facilitate independent travel. Filters and absorptive lenses, as previously noted, play an important role when there are complaints of glare, light sensitivity, or poor contrast. Very high magnification as well as enhanced contrast is especially essential in profound loss of vision as well as a profound loss in the CSF.
The new smart cell phones and digital reading devices also improve quality of life for patients with low vision. The eye is the window to the soul—and so much more. It is key to maximum functionality.

With age, vision and functionality related to vision decline. Loss of vision is associated with depression, and difficulties with activities of daily living and safe driving, as well as increased risk of injury, falls, and medication errors. Surprisingly, visual acuity is not a good predictor of visual ability.
Better predictors are contrast sensitivity, glare sensitivity, and performance under reduced illumination. Deficits worsen when low contrast, reduced illumination, and glare co-exist. Treating refractive error and ocular disease is helpful but is not enough. Minimizing functional deficits related to the environmental conditions listed above will maximize function and independence. Success requires a team approach among the patient, family, primary care provider, eye care provider, and an occupational therapist trained in vision rehabilitation. The goal of this chapter is to provide the reader with the tools to easily deliver and coordinate such comprehensive care.

Unfortunately, this percentage declined steadily with increasing age as per Table This is an increase of 15 times over community-dwelling older adults. Thus, simply increasing access to eye care would significantly improve vision and function in older Americans. Visual Decline with Aging. Vision loss and decreased vision function in older adults are related to ocular disease and age-related physiologic changes.
Rarely in life do people operate under these ideal conditions. Contrast sensitivity is the ability to distinguish an object from its background. A visual acuity chart and most street signs provide high contrast sensitivity while camouflage demonstrates low contrast. Measurement of visual function rather than visual acuity correlates highly with success in performing many common and essential daily activities.
