Is There a Big Difference Between 8.3 and 8.6 Base Curve in Contact Lenses?

My contact lens prescription is 8.3 base curve, 14.0 diameter and -3.25 strength. Can I wear contacts that have an 8.6 base curve comfortably and safely, or will they slide around/effect my vision? I’ve been wearing contacts since I was about 10, so I know how to take care of them, etc, and I know that a 14.0 diameter is much different than a 14.5 or a 15.0 because my optometrist had me try on the different sizes to see the difference, but he never mentioned base curve to me.

Thanks so much for your input!

    The base curve is a very important measurement to follow. If a lens isn’t matched to your eye curvature correctly you could have problems with moisture and oxygen reaching your cornea. This could lead to infection or even a cornea ulcer. I would absolutely follow your eye doctor’s recommendation on this measurement for the health of your eye.

    yes

  3. With contact lenses being so thin and small any change in size would be considered a big deal. So yes… the .3 difference will make a big difference. I wouildn’t risk wearing contacts that are not your exact prescription as it would cause issues somewhere. I wouldn’t wear the ones you have but infact get the ones that were prescribed to you.

    if you were to compare the lens of a 8.3 and 8.6 base curve while they are in a solution,you may not be able to tell the difference.but one will feel different in your eye because the base curve tells how it will fit YOUR eye.if it is too loose,it will slip everytime you blink and you may loose it.so even if you can not "see" the difference,your eye will know.
