High Technology devices

 

Some patients find that during their daily activities they are required to frequently switch from one working distance to another. These patients may find an automatic focusing telescope of benefit. These devices are head mounted and will refocus from distance to reading automatically. They are available by various manufacturers, under different names.

Another popular high technology device is a Closed Circuit Television (CCTV). They are used primarily for reading. They devices use camera optics to transfer written material onto a television screen. These devices can magnify images as much a 40X.

 

Conclusion

 

The field of low vision services is rapidly progressing. As technology improves, so do the results patients can achieve with the various devices. Our success is dependent on the goals, expectations and motivations of our patients.

 

If you or someone you know has subnormal vision, give our office a call to book a low vision assessment with Dr. Bojeczko. We will book an eye examination first, followed by a one hour low vision assessment. During the assessment, you will be allowed to trial various devices that we feel will meet your needs.

 

 

 

 

 

Low Vision Services

 

Our office provides eye care to low vision patients, such as individuals with advanced macular degeneration, glaucoma and retinitis pigmentosa, just to name a few. These patients may be partially sighted or legally blind, but fortunately, very few legally blind patients are totally without sight. Dr. Bojeczko has taken an interest in helping these patients and she is the low vision specialist in our office. She may prescribe magnifiers, telescopes, microscopes or special filters to help patients use their remaining sight more effectively. She is an authorizer and supplier with the Assistive Devices Program (ADP), which is a government program that covers 75% of the cost of many of these devices.

 

Most patients classified as blind actually have some sight remaining. Thanks to developments in the field of low vision, many people can now be helped to make good use of their limited vision.

Anyone with reduced vision can have problems functioning, ranging from minor to severe difficulty. There are two general classifications of low vision:

 

• partially sighted: visual acuity that with conventional prescription lenses is still between 20/70 and 20/200 (a person with 20/70 eyesight must be 20 feet away to see clearly an object that a person with 20/20 eyesight can see clearly from 70 feet away);

 

• legal blindness: visual acuity that cannot be corrected to better than 20/200 with conventional lenses and/or the patient has a restricted field of vision less that 20 degrees wide. (Note that some definitions of "partially sighted" include the legally blind.)

 

For near

 

We often use magnifiers to help patients read smaller print. These magnifiers can be simple hand magnifiers or illuminated magnifiers. They are available in powers ranging from 2X to 12X.

Some patients prefer to allow both hands to remain free, for hand writing or sewing, for example. We find that these patients prefer a head mounted device like magnifying reading glasses. These special reading glasses are similar to normal reading glasses, but magnify the print immensely. They require the patient to hold their reading material closer to their face to get additional magnification.

 

For distance

 

We use telescopes to magnify distance objects. A telescope can be mounted in a pair of eye glasses, or hand held.

If we mount a telescope in your eye glasses, it can be placed off in the corner, for occasional use, or in the centre for constant use.

The hand held telescopes are usually worn on a string around your neck and brought up to your eye when you need it. It works well for patients to see a stop light or approaching bus.

Another very popular telescope we use is much like a pair of binoculars, but lighter in weight and head mounted. They are available in powers from 2X to 7X, and are specifically designed for low vision use.
