<<I have extremely dry and itchy eyes, I've been to the gp and optamoligists a LOT they say it has something with not enough tears idk.>> As the GP and the optamoligists are both saying the your eye are producing enough tears or the tears are not staying on the surface of the cornea long enough causing dry eyes. It is strange that you aren't getting a prescription for artificial tears. I do not know if you need to pay for your prescriptions or if you are entitle to free ones, but this is an options. It would be much better to get a prescription from your optamoligists as a lot of eye doctors don't like the cornea drying out. I would think you would be paying a lot more money for over the counter artificial tears and preservative free ones are much better then eye drops with preservatives in them. Also, artificial tears eye drops come in different thickness, some are thinner and you wouldn't know how often to apply them without a optamoligists telling you. I use Celluvisc every 2 hours, it is thinner then Viscotears. It really depends on how dry your eyes are, everyone is different. At the hospital they can do a dry eye test, by putting a little bit of paper under the lower eye lid and leaving it there for a few minutes. Some people with dry eyes also need ointment to lubricate their eyes at night. As your doctors are saying you have dry eyes, pressure them for a prescription, it might be cheaper then buying drops or sprays. And if you have to lubricate your eyes often, it would become very expensive to buy the drops. If your hospital is unwilling to prescribe eye drops for you, get a referral to the Cornea Clinic at the hospital, as dry eyes do affect the cornea. Every time we blink, the tears in our eyes feed our corneas, there are nutrients in out tears, so it isn't good for our corneas to dry out too much.
