Low vision aids are devices that help people with low vision make better use of their sight. They include both optical devices like magnifying glasses and telescopes, as well as non-optical devices like lighting aids and filters. Optical devices can be used for both near tasks and distance viewing. Common optical devices include magnifying spectacles, hand magnifiers, stand magnifiers, and telescopes. Non-optical devices help with tasks like reducing glare, improving contrast, and guiding reading. Proper lighting and filters are also important low vision aids. Electronic devices now also provide additional low vision assistance options.

1. Low Vision aids

2. Vision Rehabilitation
• Are services provided to both who are
partially sighted and those who are blind.
These services include mobility training,
adaptive skills training, low vision instruction
career servicesand training, psychological
counseling and others.

3. • What Are Low Vision Aids?
• Low vision aids are devices which help people
use their sight to better advantage. These aids
may be optical lenses, such as magnifiers or
telescopes, or non optical devices, such as
visors, filters, reading slits, stands, lamps and
large print.

4. • How do Low Vision Aids Work?
• Low vision aids may make things larger: they
may make things brighter, they may make
things clearer, and they may improve contrast.
Some may do more than one thing, but
generally, all low vision aids make it easier to
see something by magnifying it to the level
one can see.

5. Optical devices are of two kinds:
• Near
• Distance
Near devices are designed for magnifying close
objects and print.
Distance devices are for magnifying things in
the distance (from about 3 meters to far
away).

6. MAGNIFYING SPECTACLES
(High Plus Reading Glasses)

7. HAND MAGNIFIERS

8. STAND MAGNIFIERS

10. TELESCOPES

16. Magnifiers for Specific Needs and Demands

18. Nonoptical Devices
• Nonoptical Devices can be Grouped According
to Their Function
1. Enhances the images and reduces glare
• Typoscope
2. Enhances contrast
• Good lighting on object or print
• Bold lined paper
• Writing guide

20. Illumination
• Need for higher levels of illumination are seen in
patients
who have:
• a. Lost cone functions, like in macular degeneration or
ARMD
• b. Damaged nerve fibers layers like in glaucoma
• c. Diabetic retinopathy
• d. Patients on miotics
• e. Degenerative myopia
• f. Chorioretinitis
• g. Retinitis pigmentosa.

21. Eye diseases which requir reduce illumination:
• a. Albinism
• b. Aniridia
• c. Corneal opacity
• d Achromatopsia

22. Letter Writer/ Writing Guide

24. Typoscope or the Reading Guide

25. Glare Reduction Lenses/Filters

26. CPF 450 (yellow color)—for glaucoma patients
CPF 511 (yellow orange)—early cataracts
CPF 527 (orange)—for macular degeneration
CPF 550 (red)—for retinitis pigmentosa
