Product Information

Biomedics 38 contact lenses from CooperVision are a high-performance lens designed to keep eyes hydrated all day. Made of a water-loving lens material, Biomedics 38 contacts deliver superior comfort, even in challenging environments.

Features & Benefits

Biomedics 38 contacts are 1-2 week hydrogel lenses. They can be worn daily for up to 14 days or continuously for up to seven days. However, not everyone can wear these lenses for a full seven days. Follow only the wearing schedule recommended by your eye care professional.

Biomedics 38 contacts have a low water content (38%), making them ideal for lens wearers with dry eyes. Contacts with a low water content dry less on the eye than contacts with a high water content. As hydrogel lenses, Biomedics 38 contacts are also very comfortable to wear, even for new lens wearers.

Additionally, Biomedics 38 contacts are tinted for easier handling during insertion and removal. The tint will not change your natural eye color.

Biomedics 38 contacts are indicated for the correction of visual acuity in non-aphakic people with non-diseased eyes that are nearsighted or farsighted and may exhibit mild astigmatism (1.50 diopters or less).

Who They’re For

Biomedics 38 contacts are suitable for lens wearers who experience dryness during lens wear. These non-drying lenses are also ideal for heavy users of digital devices as well as those who are regularly exposed to dust or dry air.

How to Put In Biomedics 38 Contacts

Biomedics 38 contacts are soft contacts and as such, you should follow the standard procedure for that type of lens. Start by washing your hands with a mild soap, then dry them with a lint-free towel. Starting with your right eye, scoop the right lens out of the case with your index finger. Rinse it with a cleaning solution that’s specially formulated for soft contacts. Inspect the lens for tears or debris, and make sure it’s not inside-out. Hold your eyelid open, then stare straight ahead while gently placing the lens on your eye. Blink a few times to center the lens. Repeat for the other lens.
