Being very nearsighted, I wanted to see something when I went to the pool. My optician offered me glasses to 60. I thought it was too expensive ... Here for 10 times cheaper it's done! The correction works very well even if it does not exactly my sight. The anti-fog coating works well but there is a problem in saline pool (on holiday): it sets the salt, I had to "scrape" the coating to remove and re-see properly.
Parcels sent on the day of the order (within hours) and delivered in one week (7 days). Glasses well protected in a double pack.
