I have dry eye problem since the past two years. My doctor has prescribed REFRESH LIQUIGEL eye drops four times a day and it really helps with the burning in my eye. But the problem again starts if i stop using the drops. I am also advised warm compresses with cotton soaked in warm water for five minutes once a day. I also have slight refractive error in both eyes for which i have attached the prescription for glasses. I want to know if it is  absolute necessary for me to wear glasses? Can glasses cure or worsen the eyesight or are they just meant to correct the vision for the moment. My most important question is that which OMEGA 3 FATTY ACID SUPPLEMENT is the best and safest and how much dosage should I take? The other medication I am on is EPOSOFT (soft gelatin capsules for gamma linolenic acid) and EVION 400 (vitamin E capsules) of for pre menstrual breast pain.
