What do these abbreviations stand for?
Also does it make a big difference if these numbers differ slightly. For example, my current prescription says my BC is 8.6 and my DIA is 14.2. The contacts that I would like to buy only come in a BC of 8.7 and a DIA of 14.0.
Would there be a noticeable(Uncomfortable) difference in how the lens fit my eye?
