My exact glasses prescription is this: Right power -7.50, cylinder -1.25, axis 35 corrected slightly better than the other eye because this one is the dominant eye.
Left power -3.75 cylinder -1.50, axis 170 What should my contacts prescription should be?
Also I notice that even with exact same prescription, different products gives slightly different correction (for example CIBA air optic seems to give me weaker correction).
Thanks for your Question
Roughly you contact lenses prescription after converting from eyeglasses prescription is
Right eye : -7.0 cylinder -0.75 axis 30
Left eye : - 3.25 cylinder - 1.25 axis 170
I would prefer that you visit an optometrist because contact lens power depends mainly on the type of the lens.
