I have only needed to wear glasses for about 3 years now.
i have polycarbonate lenses that are -9 diopters, 1.74 high index, with transition coating, anti glare coating and scratch resistant coating.
i got them during the summer and it seemed like within a couple of months after sweating and having sunscreen sweat onto them they have never become really clean again.its like they are smeared and smudgey not matter how often i clean them or what i use to clean them.even the glasses place commented when i went in to have them tightened that they seemed to not come completely clean when they cleaned them.
i'm going to my eye dr next week and he said he would check my eyes to see if i ned a prescription change.whether i do or not i'm getting new glasses and i'll ask his advice as well as the glasses place but i'm just wondering is it true that the more coatings you get on eyeglasses the more difficult it is to get them clean?
i'm thinking about not having any coatings put on or maybe just the scratch resistant one.
the transition coating drives me nuts anyways cuz it doesn't seem to get dark enough for my liking in the sun and obviously does not work in the car where i need it the most plus i have terrible night vision so i have to take them off when i walk into a dim restaurant.
do you think the less coatings the better for my situation and what i've been experiencing or does the number of coatings really not make a difference in how clean the glasses get?
Added (1). @emily: i have always had terrible eye sight but due to my eyes being complex glasses did not help.i had cataract surgery 3yrs ago and all the measurements said my lens was one strength but since my eyes are complex it turns out the measurements were off by 9 diopters and the surgeon did not want to swap it out or do a piggy back lens implant.
so i went from no prescription to -9 in a matter of 30 minutes.
i'm 26yrs old.
my dr and the glasses place recommended the polycarbonate cuz its light weight and i have a very sensitive nose.
