A.) I was prescribed comfortz eye drop which contains ( hydroxypropyl methylcellulose + dextran 70 + glycerine) .One drop in each eye 3 times a day. My concern is that if I put 4 to 5 drops in the eye rather than one drop only, is it going to be safe? many times half portion of the first drop spills somewhere else on the face. And putting extra drops in the eye really feels good. B.) I was prescribed this only for one month but as I am an avid computer user, I feel like more dependency on it . So for how long can I use it safely. And how many days of gap is required after certain period of time usage. C.) The problem is evaporation of tears related. D.) My right eye is more troublesome with pain and sometimes foreign body sensation. but left eye never gives symptoms of dryness. E.) Should I switch to a different gel based eye drop after a month like refresh gel which has higher concentration (1 percent carboxymethyllulose). Please make me competent to take decisions myself in this.
