There are commonly four types of low vision aids available in the market namely optical and non-optical aids, electronic and digital magnifiers.
It is important to understand these devices must be only used when prescribed by a medical expert, eye specialist, or ophthalmologist. A certain level of training is also required to efficiently use both optical as well as non-optical/electronic devices.
Major Types of Low Vision Aids
All four types of low vision aids i.e. optical vision aids, non-optical vision aids, electronic magnifiers, and magnifying systems have specialized task-oriented properties designed for unique purposes or activities such as close-up tasks or distance viewing tasks.
This indicates that you may need more than one of such devices to undertake a specific task depending upon the condition of your eye and the type of daily routine you follow; for example, you’ll be needing a different type of conventional low vision aid to use your computer at home, school or office, whereas you’ll need to rely on the other when you’d be reading a menu in a restaurant.
Let’s see the major types of aids for low vision:
Optical Devices for Low Vision
Optical devices are defined as devices that consist of one or more lenses that are usually placed between the eye and the object to be viewed, for the sole reason of increasing the size of the visual of the focused object on the retina.
These devices serve as an optical magnification tool that provides an enlarged visual of the object such as handheld and stand magnifiers, loupes, specialized magnifying reading glasses, and small telescopes.
Apart from significantly increasing magnification these devices can also enhance quality optics through their ability to bend and refract light.
Non-optical Devices for Low Vision
Non-optical devices are designed to enhance illumination, contrast such as reading stands, bold-lined paper, magnifying mirrors, glare control sunglasses, tactile locator dots, high contrast watches etc.
Their utility is enhanced when used with optical devices that can prove to be very helpful in reading, labeling, organizing and a host of other daily activities.
Electronic Magnifying Systems
Electronic magnifier systems, also commonly known as CCTV low vision aids, are devices that display magnified images on a monitor through the use of a mounted camera, useful in reading books, magazines, and emails.
These devices are available in different sizes and styles, depending upon the type of task you want to perform.
There are several portable handheld electronic magnifying systems that can be carried along to different places where need be such as supermarkets for reading labels and coupons, or in restaurants for reading menus.
