What is Low Vision?
Low vision is used to describe severely poor eyesight that disables a person’s ability to see clearly despite the use of prescription eyeglasses or contact lenses. This can be caused by progressive eye diseases such as macular degeneration, glaucoma, diabetic retinopathy and others.
People with low vision have varying degrees of vision loss according to their eye disease and unique eye condition. If diagnosed timely, the loss of vision can be slowed down, as opposed to the otherwise speedy deterioration of eyesight if left untreated.
For such individuals, low vision assistive technology is the best solution due to their ability to overcome visual limitations that prescription eyeglasses or contact lenses cannot.
Low Vision Conditions
There may be different degrees of vision loss for people with different eye conditions, based on which The World Health Organization has defined different classifications for low vision i.e.
- Mild vision loss or near-normal vision: 20/30 to 20/60
- Moderate visual impairment or low vision: 20/70 to 20/160
- Severe visual impairment or low vision: 20/200 or worse
- Profound visual impairment, or low vision: 20/500 to 20/1000
- Near-total visual impairment or low vision: Less than 20/1000
- Total visual impairment or blindness: No light perception
Low Vision Treatments
Low vision usually results due to critical damage to the eye such as in the case of optic nerve damage, or eye disease. It is important to understand that most low vision conditions can only be treated but not cured.
Having said that, there are different procedures and assistive devices to help manage life with low vision.
Mainly, the methods of treatment and management of low vision include:
- Eye surgery
- Low vision assistive technology
Invasive eye surgeries and medication can sometimes be useful in restoring some amount of visual function, but the use of low vision aids and assistive devices alongside can be very helpful in the management of low vision.
Low Vision Assistive Devices:
1: Non-optical assistive devices
These devices are used as an optical magnification tool that provides an enlarged image of the object.
Most common types of non-optical devices such as handheld and stand magnifiers, loupes, specialized magnifying reading glasses, and small telescopes.
Other unique assistive devices include Braille readers and books that allow a person with low vision to read text with the sense of touch through the use of special characters.
Large-print books and playing cards make entertainment as accessible for a partially sighted person as it is for a well-sighted man.
2: Electronic assistive devices
Electronic magnifiers scan the text of a page or a picture and are then converted into a magnified and easy-to-read font that is displayed on the screen.
Some video magnifiers also come with an OCR (optical character recognition) reader, that reads aloud the text after scanning which can prove to be very helpful in school or office settings. These magnifiers fulfill their purpose well, except that magnification is their sole utility.
Video magnifiers are also referred to as CCTV low vision aids and are available in different sizes and styles, depending upon the type of task you want to perform.
Braille e-reader, audiobooks and electronic books:
A Braille e-reader can translate any text into braille, which lets a person decipher whatever text they want to read. And if that comes across as tiring, audiobooks let you listen to the text instead.
Smartphones and tablets:
The customizable options in smartphones let you adjust text size according to your ease of seeing, and you can also use voice commands instead of reading text.
Low vision electronic glasses:
Low vision electronic glasses are wearable and slightly heftier than the average eyesight glasses. They have a high magnification capability to give you a clear view of your surroundings, and other features such as OCR readers.
How can low vision assistive devices help you?
Low vision assistive devices compensate for your reduced visual ability, and by doing so they help you continue your daily routine activities easily by overcoming any visual limitations caused by an eye injury or any eye condition.
