oh, personal, ok, here goes, i wear biofinity and oasys and use clear care and aquify. i dont like the idea of lens soaking all night in solution so i tend to use clearcare for over night cleaning disinfecting and aquify after removal at night for a clean rub. but a few days ago i tried leaving lens in aquify overnight, the next day upon insertion, lens felt really good, in fact, i went the whole day, 18+ hours without a lens issue. so i start thinking about wetting angle and find that wetting angle of clearcare is 112 degrees after 10 hours and 98 degree for aquify, maybe that's why i had a better experience after soaking in aquify, the wetting angle is less. but it could just be allergies too, i have to take claritin or zyrtec somedays because of eye allergies, and allergies are never consistant, some days good, some days bad. but then i read about otifree-replenish with tearglyde having a wetting angle of <10degrees after 14 hours, WOW, but then optifree replenish does have a higher staining with oasys and biofinity. so what do to?? i think i'll try optifree replenish for 1 bottle and see if i notice a difference in how lens feel after 18+ hours, see if the lens feel any better than aquify or clear care, 1 bottle isnt going to hurt my eyes just to try it. somedays, i have to take lens out for 10 min, soak in aquify the reinsert, only takes 1 min, then my lens feel very refreshed.
contact lens wear in highly individual and personal, you just have to find the right combination of lens and solutions, cleaning habits and disinfection regime that works for each individual. i know people who find a system that works and they dont want to change, but there may be something better available, take biofnity for example, high Dk/t, low modulus, high water, very low wetting angle and no surface treatments, is this the perfect lens or what? but still some cant wear biofinity because of allergies, so i think the next best lens is oasys, but there seems to be many allergies to oasys as well, so it goes on.....and on.....and on......
