One of the essential parts of our body is the eyes. It gives us a sense of direction and clarity. They make us see the world’s beauty and the people we love. Unfortunately, there are people who suffer from eye impairment, like low vision. Low vision is caused by age-related macular degeneration, glaucoma, diabetes, and cancer of the eye.
There are several classifications of low vision:
- Loss of central vision – not being able to see things in the centre of your vision
- Loss of peripheral vision – not seeing things out of the corner of your eyes
- Night blindness – not being able to see in low light
- Blurred vision – objects near and far appear out of focus
- Hazy vision – vision seems like it’s covered with a film or glare.
Having visual impairment can be very challenging and, at the same time, dangerous. Fortunately, glasses and contact lenses can help visual impairment, but low vision, however, can’t be corrected by glasses, contact lenses, or even surgery. Instead, there are several low vision aids that can help them function properly and improve their quality of life.
Low Vision Aids
Low vision aids are devices that can help improve visual performance in people with low vision. Low vision aids are task-specific and are categorized into two:
- Near optical devices – used for within arm’s reach visual clarity and can be used for activities such as reading, writing, sewing, and crafting.
- Distance optical devices – used for visual clarity of beyond arm’s reach distance or of things from a great distance. These can help you with activities such as reading street signs, reading on a whiteboard, watching television, seeing a movie or a sporting event, and seeing faces better.
Low vision aids can help with daily tasks that you may find difficult to perform because of your limited vision. Here are several ways how low vision aids can help regain independence and improve quality of life:
- Gives Better Distance Vision
Telescopic Spectacles are used for better distance vision, magnifying optical systems or miniature binoculars are integrated into the eyeglasses. Its compact and lightweight features offer great convenience while still maintaining brilliant image quality. Your job as a professor teaching a class will not be so difficult anymore. Leisurely activities such as watching a movie or an opera are something you will enjoy. Driving will not be tricky and dangerous as well.

- Provides Better View Of Small Printed Items
There will be instances you need to read very small printed items and a low vision aid like a hand-held magnifier could help you with that. The magnifiers provide a detailed magnification of an object that is standing at a close distance. They vary in different shapes, sizes, and features. It could be handy in reading price tags in malls and menus in restaurants since they are portable, though it may not work as well as the glasses since your hands are occupied. On the plus side, it is less expensive than the other low vision aids.
