This is apropos of the survey posted earlier.
Esha appears to be a non-profit venture, which seeks to assist organisations that conduct business with, educate or employ blind people. It can help to get visiting cards braille-enabled, conduct theatre workshops to sensitise people to the special needs of the visually impaired and help with the creation of environments that can be inclusive enough for them. It also has a blog focussed on related issues.
However, the idea appears to be somewhat before its time, since, as far as I know, not many businesses in India employ or even seek to employ the blind at present. I am not aware of many blind entrepreneurs who deal with large business houses either.
As far as educational institutions are concerned, I believe the blind generally have to seek admission to special schools and colleges in this country, where there hardly are any sighted pupils.
So, unless Esha can convince corporate India to invest heavily in the creation of employment opportunities for the blind or regular educational institutions to admit blind students, the only sightless beneficiaries of its efforts seem likely to be those on its own payroll, who, obviously, are not going to be more than a few.
