What an ignorant statement. Vinegar is safe to drink... but I don't think you'd want to rinse your contact with it. And maybe educate yourself before posting such a coment. The amoeba that causes this can indeed live in tap water...

Don't be absurd. You wouldn't rinse your contacts with Coca-Cola either.

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.

Your anecdotal statement doesn't bring much to the discussion, but there surely are great differences in tap water quality around the globe.

I have just found an investigation why the risk for AK is higher in the UK. (seems to have to do with tap water tanks) https://www.ncbi.nlm.nih.gov/pubmed/14691169

That would make sense. Water tanks would be breeding grounds for the amoeba.

(The UK housing stock is slowly converting over to plumbing that eliminates the water tanks, but lots of older housing will still have a water tank in the loft somewhere.)

You should NEVER rinse your contacts with tap water.

RGP lenses can be rinsed with tap water.

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.

I quote from my Baush + Lomb cleaning solution bottle:

- Wash your hands with mild soap

- Rub both sides of the lenses carefully with two to four drops of cleaner

- RINSE OFF THOROUGHLY WITH FRESH TAP WATER

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.

Alternatively, from the site:

http://www.bausch.com/ecp/our-products/contact-lens-care/gas...

It does say to rinse them with tap water, but also to rinse & soak with solution afterwards...presumably negating the dangers of the tap water.

Why did you chose to ignore the point 4 of the instructions after reciting the first thee points? The point that completely removes all residue from the tap water.

What country? In the UK the advice for Boston is to use tap water only if it's been boiled and cooled.

Here in India, Bausch+LOMB's ReNu lens solution is popular.

Referring : https://images-na.ssl-images-amazon.com/images/I/91eS0p3YC3L...

It mentions only to use the solution, no tap water.

That appears not to be the case.

Yep, the way I read that is to rinse the lenses in water after cleaning them.

Horrid.

Glad I ditched using my own lenses now in favour of glasses. I still have a good supply of them .. just never liked the poking around in the eye business.

I know it might not persuade you, but I just recently learned of a good friend that has some scaring from an infection from contact lenses. When I sent him this link he said a coworker of his just got an eye infection also. That being said this is all anecdotal. I would love to see a more definitive study though on this.

That isn't what the story said. I think the issue is that your gut and digestive system may cope with parasites, bacteria and the amoeba that causes AK - the eyes defence mechanism will be different

It would seem that this is not an isolated incident. A quick Google produces quite a lot of warnings about tap water.
