I wouldn’t bother with it. I was told 35 years ago I had astigmatism in one eye, and that’s why I had to have two different contact lenses, one for left and one for right. About 25 years ago, I started experimenting by switching my lenses, or wearing a left lens in each eye one day, and a right in each eye another day. I did this for months. Eventually my eyes were the same and now I can get one box of lenses and use them in both eyes. So much of what they tell us is just an excuse to make more money. IMHO.
I agree with you. The eye doctors profit margins have been squeezed, so this sounds like an up sell attempt, as on a car lot.
