After buying perscription sunglasses for year, II normally go with the brand that they are selling, MUCH cheaper than getting a BRAND NAME pair. That being said, I DID purchase some Cosstas, once and then my eyes changed. This was back when they were like $450 or so, not $600 to $800 now. I replace them every year, as my insurance company allows that. I normally have my eyes change a little bit each year, if it is not bad, I hang onto the older pair. Getting a time for a new pair in April. Hope this helps. Tight lines, keep safe and good luck.
