According to World Health Organisation (WHO) global report, there are at least 2.2 billion people who face some form of vision impairment or blindness, of whom at least 1 billion have a vision impairment that could have been prevented.
These 1 billion people include those with moderate or severe distance vision impairment or blindness due to unaddressed refractive error, as well as near vision impairment caused by unaddressed presbyopia.
Based on studies, the leading causes of vision impairment was observed to be uncorrected refractive errors and cataracts, with the majority of people with such impairment over the age of 50 years. Population growth and ageing can increase the number of people with vision impairment. There are also many who are born with limited vision or blindness or have conditions that are a result of an accident.
The reasons for vision impairments or blindness may be many, but the fact remains that technology is proving to be a powerful tool in making a difference to those with disabilities. Technology today is bridging gaps in the space and are providing numerous opertunities to those with such disabilities.
Here we discuss 6 tools that can make the lives of persons with visual impairments or blindness, a little easier:
BlindTool is designed for visually impaired people, enabling them to use their phone to see.

‘Be My Eyes- Helping the blind' is designed for visually impaired people. Users can request for help from sighted volunteers who will be notified through mobile.
