In case someone out there knows.
The lady at the office won't tell me and said because it's been almost 2 years since my last exam, I have to go in and get a new exam to talk to the Doctor.
Anyway my eye prescription is -2.25 in both eyes and it's been between -2.00 and -2.25 for the past decade.
I found some cheap prescription swim googles on clearly contacts for $25 shipped but it's only -2.00 or -2.50, -2.25 isn't available.
Obviously I think it's worth a shot to opt for the -2.00, I don't think -.25 will make a huge difference?
