My colleague had a tough time. his car breakdown and he embarked on four hours treking under the sun in two days. on the third day, he failed ill and was admitted. all of a sudden, he noticed he could not see far away object clearly niether could he view letters clearly. His optician advised him on glasses but he said he doesn't need glasses as the momont. For the optics, are there solution/options to get his sight back on track

i don't understand, what's ur point?

He totally brought this upon himself, are there no alternate means of transport other than treking under the hot sun. Anyways his optician has already given him some advice, he should do just that or his eyesight will continue to deteriorate.
