Initially, I feared the burn of these drops, but it didn't last minutes for me, it lasted less than a minute. I didn't time it, but it wasn't as bad as I thought & felt like it lasted under 60 seconds. After that, my eyes felt great & my visioned improved, so it does everything Soul Vine said it would. Highly recommend. Had my brother help apply the drops first few times [lay horizontal, eyes closed & put in corner of eye where tear ducts are, then open eyes & close eyes a few times until you feel drops; ONE EYE AT A TIME]. Also, don't over use or you will get dry eyes [I was psyched I could handle the burn, loved the results & used too often]. No problem that lubricating eye drops couldn't fix, but I don't overuse these drops anymore [live & learn].
