I suggest looking in to taking a daily multivitamin, adding a good amount of fish oil
and flaxseed oil supplent, avoid lots of wind, dust, sunlight,ceiling fans,
and dry hot air. Look into allergy drops like Pataday, frequent use of preservative free artificial tears, and possibly punctal plugs and restasis drops long term. Part of your problem may also be from using Opcon (a vasoconstrictor) for too long. You can get a lot of rebound redness when you stop it.
