... diopters. You are correct in saying your tear film affects matters. Those with dry or moist eyes may need different contact pescriptions. Also your vision with contacts fluctuates depending on the dryness of your eyes. I guess this is why sometimes they just pescribe the same power contacts vs. ... (18 replies)
... The percentage is not fixed.Correction at -7.00D is .50D,correction at -10.00D is 1.00D.These corrections dont take into account the effect of the tear film forming a tear lens and the image size difference formed on the retina with cls versus eyeglasses.The most accurate way to refine the cl power is to perform an overrefraction over the cls while looking at the eyechart(at...

... Are you kidding me? How can you tell somebody over the internet what power contact lenses they should be wearing without examining them? Are you a doctor? NO Did you examine the creator of this thread? NO If this can be done over the internet, then why are optometrists and ophthalmologists going to school for so long? (18 replies)
