Lube or Lube Plus

Both tubes are carbomer gels — the base that makes Optixcare stay on the eye instead of streaming off it. The Plus adds hyaluronic acid, a molecule that binds many times its own weight in water and releases it slowly between blinks. That is the entire difference, and it decides everything.

Choose the original Eye Lube for situational dryness: the dusty hike, the windy pickup bed, the long drive with the window down. The eye is healthy; it just needs a top-up. At $15.99 either way, the original does that job completely.

Choose the Plus when dryness is a condition rather than an event — senior dogs whose tear film has thinned with age, brachycephalic breeds whose prominent eyes sit exposed to the room, cats wintering beside a radiator. Chronic eyes need moisture that lasts from morning to evening, and the hyaluron is what buys those hours.

If the answer turns out to be 'Plus, twice a day, indefinitely,' switch to the three-pack or the Home Kit: the same tube drops from $15.99 to $14.00, and the spare in the drawer means the routine never pauses while a delivery travels.
