Brite Eyes III is a very excellent product for dry eyes and for helping to clear cataracts. However, it will not help "hyper-mature" cataracts, i.e., cataracts that have been completely mature (dense and opaque) for very long. Also, they may or may not work in dogs, depending on the type of cataract. Ordinary, age-related cataracts are much easier to clear than genetic "juvenile" cataracts, although the drops do seem to help hold the line in most of these cases, with diligence on the part of the owner. A diet rich in fresh, brightly-colored vegetables and fruits and dark, leafy greens helps also (for people and dogs). For the person complaining about the bottle: these bottles are not meant to have the tips cut off. There is a plastic sleeve around the neck of the bottle under the cap. Remove the cap, slip off the sleeve and discard and screw the cap on securely. A sharp point in the tip of the cap puntures the tip of the bottle, making a hole the correct size for dispensing.

Really helped my dry eyes from blood pressure meds. Additionally had a mild positive effect on mood that led me to explore oral carnosine.

Plain and simple as that. I'm using it on my dog and the improvement is noticeable.

i ordered 3 boxes (6 vials) of the NAC eye-drops for my old doggie's cataracts. It's a super bargain, considering the veterinary version (ocluvet) cost 4 times as much. Surgery was not an option, given my very very old dog and a USD$3000 price-tag. Just 10 days after placing order (by int'l airmail), the box was delivered to my doorstep in Singapore. Have been applying to my dog's eye for almost 3 weeks now, already see reduced opaqueness and less redness in the affected eye. :)

Eyes aren't as dry and I seem to have slightly improved night vision.

My cat, Felix, had 2 eye surgeries for dry eye performed when Hurricane Frances was here in Florida. My Vet wanted to put him on Cyclosporin eyedrops every couple of days for life. I did a little reasearch and for several years now, he gets his eye drops (which I order from you) about once a week and he's happy and not had a problem since.

I have been taking this product for 3 weeks now to reduce, prevent existing cataracts. I have been a star-gazer all my life and I noticed last night I was able to see more stars than I have ever seen in a long time. I was able to see Pleiades as individual stars instead of just a haze. I also saw 3 meteors and they were faint. The last few years I could only see the bright meteor's.

My Blepharitis has been quita a struggle. Eye drops with Carnosine are supposed to help. There are expensive in Canada and hard to get. These were very reasonable in price in comparison,nad I am getting some relief.

Burned eyes tremendously, for one minute, the first use. Not so much burn second time. Still burned third time so I discontinued use. I have heard raves about this product healing eyes. I am checking with my optom.

This is one of several companies making these NAC eyedrops - for cataracts. These bottles are cheaply made and the hole made by screwing the cap down is always different in size AND SHAPE so that either no drops come out or I get doused like with a garden hose. Every other company makes proper bottles. Why can't Lief Extension also put these drops into a good bottle?
