Another contact lense question, might be difficult to answer....?

Question

I got my first box of contacts today, and I was curious what the prescription numbers on the box meant. The websites I went to made sense, but I'm still a little confused about the power(sphere) of one of my lenses... The websites all say that power for myopia ranges from -0.50 to -20.00, my prescription is -0.25. I'm just curious WHY my prescription would be outside the range provided in the websites. And yes, I did read the box correctly. (its the number beside the 'd').

I'd appreciate if anyone with actual knowledge about this would answer. Thanks.

Answer 1

That is just because there aren't many brands that start that low.

Most brands only start at 0.50

If you can find your brand on a site, it will show it starting at 0.25...
