Optive Omega UD 0.4ml x 30

Most chronic dry eye is evaporative: the oily outer layer of the tear film, made by glands in the eyelids, fails, and tears evaporate faster than they are made, however many watery drops go in. Lipid-containing tears address that actual defect, replenishing the oil layer to seal moisture in, and comparative trials show they outperform aqueous-only drops in exactly this majority subtype, the dryness that flares in wind, aircon and long screen sessions. Optive Omega adds omega-3 oils to the lubricant in preservative-free single-dose units, feeding the lipid layer with each drop for the evaporative pattern of dryness.

If drops help for minutes and the burning returns, you are probably refilling a bath with no plug. Replacing the tear film's oil seal treats the leak itself. If plain watery drops keep failing you, that is the diagnostic clue: the problem is evaporation, and this is the layer that stops it. The single-dose format also makes it the cleanest travel and office option, one vial per session, nothing to contaminate.
