hi all...
thanx for all first for telling about their courses...
about me...i finished the EYES course and may be i had the most stupid questions that may be given to anyone....although my hard luck in lottery...but i was smart enough not to pick the cards which were infront of me and seeked the far cards...so i fooled the lottery...lol...
anyway
my 2 questions were...
1- what does 6/12 mean?
its so obvious...a patient from six meter can see what a normal person sees from 12 meter.....
2- what is myopia and what its correction?
myopia is a refractry error when the convergence of light rays comes infront of retina,,,,and its correction...by using diverging(minus)lenses to shatter the rays to hit the retina properly in glasses,or contact lenses,,,,and by laser therapy!
u have to say contact lenses,,,,not just lenses,,,,thats it for me...
this was the perfect answers not mine specifically!!
