Very happy with my Biomedics 38 contacts

My eye doctor recently recommended that I give Biomedics 38 contacts a try because my previous contacts weren't doing the trick. I decided to buy them, and up to now they are so much better in every way than my old ones. I'm happy I bought these!

Biomedics 38 have met all my expectations

So far Biomedics 38 contacts have been really great for me. They keep my eyes comfortable for up to 2 weeks, all without making them dry.

Best contacts Ive tried yet

Biomedics 38 contacts have really been a saving grace for my eyes. I have tried so many different brands, but they all made my eyes dry and itchy. These are so much better than my previous contacts.

great for long time wear

I keep my biomedics 38 contact lenses in for two weeks at a time. A lot of people can only keep them in for one week, it just depends on your type of eyes. I would definitely recommend these lenses though.

Product Information

The higher water content a pair of contact lenses has, the more comfortable they are. While that seems like solid logic, it’s not necessarily true. While higher water content allows lenses to give the eyes more moisture initially, the higher water content can also causes lenses to dry out more quickly. Also, being exposed to air conditioning and extended periods of staring at a computer screen while wearing contacts with a higher water content can cause irritation.

For those who want or need contact lenses with lower water content, Biomedics 38 contacts by CooperVision is a great option. The lower water content facilitates superior handling while still providing durability and dehydration resistance. Unlike other lenses you may have tried, they’ll keep their shape and won’t curl or roll up. Biomedics 38 contact lenses feature a patented design, providing a superior fit and delivering the pinnacle of comfort and performance. As a matter of fact, these contact lenses are manufactured with advanced Liquid Edge Molding (LEM) for a superior level of smoothness on the both the surfaces and edges. What does this mean? Edging and polishing by hand is completely eliminated, resulting in a flawless finish for each lens.

Biomedics 38 contacts, also sold under the name Ultraflex 38, are tinted in order to more easily find them in the solution. The tint will not change the color or appearance of the eyes, however. Biomedics 38 are 1-2 week disposable contact lenses and may be worn for two weeks (with nightly removal and cleaning) before replacement. For some individuals, extended wear with Biomedics 38—for more than 24 hours or while sleeping—may be possible. However, this wear schedule must be approved by an eye-care professional and gradually introduced. Even though these contact lenses resist dehydration with their lower water content, they can dry out and become brittle if exposed to air while not in the eyes. In some cases, the lens can be rehydrated by following the manufacturer’s instructions.

These contact lenses have a long history of customer satisfaction (you’ll find many five-star ratings and glowing recommendations online). If you shop at for your supply of these CooperVision bi-weekly contact lenses, you’ll enjoy the best value around. With hassle-free returns, 100% money-back satisfaction, and quick shipping, you can’t go wrong with purchasing your contact lenses from
