Now that I know my Rx and seeing that Rx swim goggles arent that much, I had a question.

One of my eyes is -3.75 diopter or whatever it's called. The other is -4.

I noticed Rx swim goggle go from -3.5 straight to -4.

Now for my eye that is -3.75 would it be better to get the -3.5 or -4?

Hopefully some of you have experience in this.
