Improved sex with contact lenses?!

July 2018 | Granted that the title of this post is most definitely clickbait but I have had two patients tell me that their awesome new contact lenses really have made their lives better! [1] on her follow-up assessment a newly single woman with great distance vision but poor near vision... "I don't have to pull our my reading glasses to decide which way to swipe on Tinder!" and [2] a very very nearsighted man recently reports wearing his new [extended wear] contact lenses to bed let's him see his partner better.
