Wearable Low Vision Aids and Reading Machines

Many low vision devices can make reading easier and more rewarding for people with macular degeneration, retinitis pigmentosa, tunnel vision and other low vision conditions.

Here are some examples of low vision aids for reading:

  • Magnifiers. Hand-held magnifiers are among the most affordable low vision devices for reading, and some are illuminated to make print even more visible.
  • Reading glasses

Some Thoughts From Audrey Demmitt Rn Bsn And A Visionaware Peer Advisor

Its important to have the right magnification strength prescribed for you. Too much or too little magnification wont work well, and this can happen if you are just guessing at the magnification power you need. As your need for magnification increases, the size of the magnifier lens will become smaller. This is the science of optics and magnification: the stronger the power, the smaller the lens will have to be.

My clients often do not understand this and state that they want both a large viewing area and strong magnification. I wish it was possible to have a magnifier with a very large lens and very strong allover magnification but it is not. There just isnt a magnifying device available that will do that optically and provide any degree of magnification with the exception of an electronic video magnifier.

I always try to advise people to start by having a low vision evaluation and learn the particulars of their eye condition before they try to purchase low vision devices on their own. Why purchase a variety of over-the-counter or mail-order devices that dont work? In the long run, going to a low vision specialist can save you money, time, and much frustration.

The Low Vision Specialist

Its recommended that you see an eye doctor who is a low vision specialist to determine the right types of devices that will help you with the everyday tasks you want to perform. Some doctors may recommend starting with one or two devices to see how you manage, and then adding additional devices as you become used to working with the devices you have.

It is extremely helpful to both you and your doctor if you can make a list of the tasks or activities that are most important to you and share that information with him or her when you have a low vision eye exam. Its also helpful to bring along samples of your everyday tasks, such as mail, bills, or needlework.

The low vision service is incomplete unless youve been taught how to use the devices that have been prescribed for you. After youve been prescribed low vision devices, such as a magnifier or telescopic glasses, its important to learn how to use them when you get home.

Before any optical or non-optical device can be effective and comfortable, you will need to:

  • Be motivated to use the device for specific tasks
  • Be confident that the device has been appropriately prescribed
  • Understand how to maximize the use of the device
  • Understand the potential and limitations of the device.

Low vision optical devices can be grouped into two basic categories:

Optical Aids For Low Vision

Optical aids for low vision directly enhance vision through the use of lenses. Lenses are placed between the eye and the object to be viewed to enhance vision. Lenses work by using magnification to enlarge the object in the field of vision. Optical aids include low vision magnifiers, such as stand and hand-held magnifiers, telescopes, low vision glasses, and glare-control devices with tinted lenses. Low-vision optical aids differ from regular glasses or magnifiers due to enhanced magnification power and higher prescription strength.

Best Illuminated Stand Magnifier

System Vario Plus is the illuminated stand magnifier. A system with the widest range of illumination settings and magnifications, making it the most popular illuminated magnifier series of all time. Both the head and the handle are available separately.)

The System Vario PLUS has a big lens size that provides a wide field of view, allowing you to see more reading material at once. Because of the incorporated magnification head, it gives optimum brightness. For enhanced ergonomic comfort, the lens head can be turned toward the user. Compatible with Eschenbachs two System Vario handles, the #1599-10 incandescent battery and the #1599-144 LED battery with three color variations.

There are much cheaper stand magnifiers out there but the problem is most of them have long legs and require you to have to almost stand up over the top of them to use them. This style is much more comfortable for long periods of use.

As Low Vision Aids For Macular Degeneration

People suffering from age related macular degeneration have their central vision affected by the disease, while their peripheral vision or side vision continues to function better for a much longer period of time.

IrisVision glasses serve as the best low vision aid for macular degeneration, because these enable you to shrink the whole image captured by the camera lens to a much smaller area, which can be moved around across your field of vision , expediting your leftover vision like no other low vision aids.

This means you can still view the faces of your loved ones by moving the image to your peripheral vision though your central vision fails to pick it up.

Ial Sight And Blindness

When patients are classified as legally blind, they have not always lost all of their visual function. In the United States, blindness is defined as reduction of central visual acuity to no more than 20/200 in the better eye with a correcting lens or limitation of the central field of vision to less than 20 degrees at its widest diameter. The World Health Organization defines blindness as visual acuity below 20/400. The definitions of blindness used by the WHO and the US are intended as legal classifications and they do not necessarily convey important functional information. Most patients classified as legally blind can still distinguish between objects, can read with low-vision aids and maintain their independence with visual aids and training a smaller number can distinguish only the difference between light and darkness. Low vision is a visual impairment that cannot be corrected by medicine, surgery, or conventional aids and interferes with functional vision. Many people who are not legally blind are visually impaired and need low-vision rehabilitation.

Braille is probably useful when the person has profound loss of vision and cannot read type, or read fast enough, with a CCTV or strong magnifier. If possible, a child with profound vision loss should be taught print letters and numerals to aid visualization of text, even if they eventually have to switch to Braille.
