The goggles are ergonomic enough to train and to race (in open water are excellent) The vision is wide and the optical correction is really of good quality

But hey--it's a huge improvement over the big blur that I was dealing with before

My first time wearing the Vanquisher and I am surprised

It doesn't seem to pull my hair as much

It's wonderful that they're no more expensive that the non-vision-corrected model

If you are looking for optical goggles with different prescriptions in each eye, consider purchasing a pair of goggles in each prescription, then using swapping out the eyepieces to make two pair of goggles with two different prescriptions
