When someone says, 'I can't see', what do they mean? Is it as simple as putting on a pair of glasses? No, it is not.
The definition of low vision:
Low vision/vision impairment is reduced vision, that can’t be improved with prescription glasses, or contact lenses, and has the affect of limiting a person’s ability with tasks, activities or functions.
Therefore, people do have SOME vision, but have a variety of vision limitations, eg
• Unable to read numbers on bus, tram, train timetable
• Unable to differentiate different denominations of coins and notes
• Unable to see people's faces
• Unable to read menus or forms
• Unable to see where to sign a form
• Unable to judge steps, curbs or where a cup of tea is on the table
• Difficulty crossing the road, or navigating a new area
These are just a few examples of issues, people with low vision encounter daily, and many times a day.
