[Blindmath] can visually impaired people study math in higher level?

[Iqbal Hosen]

hi all,
i would like to have some information in the field of math studies to encourage the visually impaired people of our country. i would be very happy if anyone could please tell me whether visually impaired can study math in the higher level. if there is any blind math teacher, or visually impaired can study science. in our country even it is far more difficult to study math in the secondary level. hi folks, don't mind if these questions are silly in the context of yours. if i have better information about math, i would be able to attract my students in the field of math. 

wishing you all the joy and happiness.
i would be looking forward eagerly to hearing from you again. 
iqbal.
