Vinegar is an acid. You said if it's safe to drink it's safe to rinse your lenses with. I'm pretty sure your cornea will be damaged if you rinse your lense with vinegar and stick it in your eye. So your point that if it's safe to drink it's safe to rinse a contact lense with is patently false.

More to the point, your stomach has acid that can kill microorganisms in tap water. Your eye has no such defense.

This is a bit of misinformation that is currently still on the packaging for gas permeable lenses- not the same as soft lenses. I personally know a number of hard lens wearers who contracted AK after following these instructions to rinse their lenses in tap water. I am campaigning to get this advice changed as soon as possible. Would love some support.

You forgot to list step 4 which is to put the lense in the disinfecting solution. We're talking about rinsing the lens with tap water before placing into the eye.

They also specifically state NOT to use tap water:

"Never rinse your lenses in water from the tap.

Tap water contains many impurities that can contaminate or damage your lenses and may lead to eye infection or injury."

following on from that:

3 RINSE OFF THOROUGHLY WITH FRESH TAP WATER.

4 Place lenses in empty lens case and fill with fresh Boston ADVANCE Comfort Formula Conditioning Solution. Soak lenses for at least four (4) hours (or overnight) before wearing. Always use fresh solution for soaking and storing lenses.

So it's not stick tap water in your eyes so much as rinse them with tap water then soak in disinfectant for four hours.

Which solution are you using? Fellow contacts user here (monthlies), I'm looking at the side of my B&L bottle and it says to use nothing besides the solution.

"I selectively quote from my cleaning solution bottle and leave off the MOST IMPORTANT STEP." Way to science it up in here. We've been schooled, for sure.

Emphasis added?
