EDIT: So apparently a bunch of people are all pissy that I tagged this as Lapidot. The tag’s gone now, dry your eyes. I like Lapidot. This video is a joke. I can’t even share something funny/cute/stupid that I made without getting shit on this site. You’re getting your panties in a twist over a stupid AMV with a Taylor Swift song starring cartoon rocks. Grow tf up. God, I forgot what babies people on this site can be. It’s just shipping. Excuse me, I need to go blow my brains out.
Many patients are surprised to hear their optometrist or ophthalmologist recommend against using Visine, or other similar eye drops such as Clear Eyes. Why not? They work don’t they?
Yes, these drops take away the redness, which is why people use them, but they doesn’t fix what’s causing the redness. Invariably the redness comes back, and you find yourself on the red-eye carousel with drops –> relief –> redness –> drops –> etc. Some believe the “rebound” is worse than the initial redness.
The active ingredient in Visine is “tetrahydrozoline hydrochloride”, which constricts blood vessels. When applied to the eye, it causes the tiny blood vessels in the conjunctiva to constrict. When the effect of the drug wears off, the blood vessels dilate again, giving the red appearance again.
But wouldn’t it be better to target what is causing the blood vessel dilation in the first place? But there are SO many reasons why your eyes may be red… including dryness, blepharitis, contact lens irritation, allergies, iritis, infection… if there is a question about the source of your eye irritation, it’s best to see an eye specialist. But there’s no harm in trying some good, quality over-the-counter artificial tears, such as Genteal or Refresh, with some old-fashioned warm compresses to treat any existing blepharitis.
Visine and other vasoconstrictors are best used in moderation, a good rule of thumb is for no more than 3 days straight.
