Blind Visually Impaired Non Optical Low Aids Vision

Visual impairment is the term used to describe when a person’s ability to see has reduced to such a great extent that it cannot be corrected using traditional methods like glasses and lenses. A total or virtually complete loss of eyesight is referred to as blindness or blindness in general. Refractive error, also known as a disturbance in the path of light within the eye, is the main cause of vision loss in the entire world.

Through the darkness of visual impairment, technology and human ingenuity have illuminated some very smart low vision solutions, such as magnifying glasses and an entirely new writing system called Braille. Optical and non-optical low vision aids are the two main categories. Living with limited eyesight or blindness requires knowledge. By learning which optical and non-optical aids can be beneficial to them and incorporating visual impairment coping mechanisms into daily living, people with impaired vision can improve the quality of their lives. Now that we have a better understanding of non-optical low vision aids and non-optical gadget examples.

Low Vision Aids

Non-optical gadgets are described as tools that are primarily made to make it easier for people who are blind or visually impaired to read and write effectively. The development of technology and the internet has greatly increased the range and quality of non-optical assistance. For instance, producers add bouncy, bright markings to the equipment to assist clients who are blind. There are talking clocks, watches, timers, and clocks with large, simple faces that make it easier to tell the time. There are non-optical devices that enable you to perform tasks that are practically difficult for persons who are blind or visually impaired, such as threading a needle or keeping a pair of socks together, among many other tasks.

Example of Low Vision Non Optical Aids

Sometimes something as straightforward as better lighting can considerably assist a person who is blind. A thin, coloured sheet of translucent plastic is the most basic non-optical low vision solution. Colors like yellow or red increase contrast when held over the page to be read, making the alphabets on the page easier to see. The Writing Guide is one example of a non-optical instrument. A writing guide is a non-optical low vision aid that improves writing for those who are visually impaired. Black cards with horizontally oriented rectangular cutouts serve as writing guides.To write more clearly, place this black card over a page. It has four rectangular holes. The dials of some telephones, watches, and books are made conspicuous and much larger than what we are used to seeing; making the dials of telephones larger aids vision.

A few nations have also begun to employ guide dogs, which are well-trained canines that accompany a visually impaired person everywhere they go. Such guide dogs have undergone extensive training to adapt to the way of life of humans. Such canines know when to cross the street and how to keep their blind or visually impaired people safe by shielding them from the outside world.

Computers and the internet must also be included. For the benefit of those with visual impairment, Microsoft Windows comes with a built-in screen magnification tool that enlarges a specific area of the screen. Screen reader software enables even completely blind persons to utilize computers. So that one can utilize a computer without having to look at the monitor, they turn the text and icons into speech. Since we now have audiobooks for every best-seller, text-to-speech technology has been widely used so that persons with visual impairments don’t have to rely solely on their eyesight to read literature.
