Congratulations to your son, and for you entering into a vast world of technology and experiences few can imagine.
My 21yr old son, who is totally blind is in his 4th year at Exeter Uni, as a triple language major, moving on to law studies.
incredibly in the groove, has raced go-carts, and took the life skills driving course while at RNIB Worchester.
There is so much cutting edge work being done for the VI (visually impaired) that leaves us sighted folk in awe.
I tell my son often that I am 3 times his age, but only half the man he is.
Please PM me if I can help.
