Waiver Criteria:

"CCT/PJ Medical Standards
Vision standards:

20/70 uncorrected vision, correctable to 20/20 each eye

Maximum waiver standards-

20/100 both eyes corrected to 20/20, or 20/200 worse eye-20/70 better eye, corrected to 20/20 both eyes."

I got this from the waiver criteria section of this sight. My optometrist said my vision is 20/20 uncorrected with both eyes, but individually my left eye is worse than my right eye. When the waiver standards says 20/20 both eyes does that mean 20/20 vision using both eyes at once or 20/20 in each eye individually?

Individually. If your eyes are 20/20 uncorrected, you'll be fine. Even if one eye is slightly behind the other, you should be well within the 20/70 limit.
