Low-vision devices are designed to improve visual performance in children with low vision, thus enabling academic and social adaptation and providing enrichment of daily experiences.
There are many different types of low vision aid, including: magnifiers – low vision aids that use either lenses or cameras to make things look bigger. products that use colour or contrast to make them easier to see and use. products that are larger than standard, e.g. a larger wall clock. large-print products.
Optical Low Vision Aids. Optical aids use magnifying lenses to make objects look larger and easier to see. Correctly refracted glasses. The child needs a proper cycloplegic refraction (with eye drops), and measurement of accommodation (ability to see close up when reading or playing).
Smart glasses. High-tech glasses can provide even higher magnification, read text aloud, and help you navigate the world around you. Braille displays. If you read Braille, these devices connect to your computer and translate what’s on-screen into refreshable Braille dots you can feel. Smart canes and apps.

Low vision aids (LVA) or low vision assistive products (LVAPs) are devices that aid people with low vision and allow them to use their residual vision for better living. LVAP work by making the objects appear bigger, brighter, and blacker or more closely, with improved contrast. [2]
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. Other magnifiers that are mounted on height-adjustable stands or supported by a band that hangs from your neck also are available.
