The five best contact lenses for sleeping in

THE FIVE BEST CONTACT LENSES FOR EXTENDED WEAR AIR OPTIX NIGHT & DAY 1 They replace the original generation of CibaVision extended wear lens originally marketed as Focus Night & Day. Night & Day are manufactured with lotrafilcon B, a silicon hydrogel material with a 24% water content and are a high modulus lens. Having a high modulus means that these lenses are easy to handle as they sit up well on the finger, and it is also more simple to determine if they are inside out. AIR OPTIX NIGHT&DAY AQUA CHIAGVISION. PUREVISION 2 The PureVison 2 lens is manufactured using balafilcon A which is a silicon hydrogel material with a 36% water content. Although a reasonably thin lens, because of balafilcon A's high modulus it is easier to handle than the original PureVision lens. The optics have been updated with what B&L call "High Definition Optics" to reduce spherical NEW BAUSCH+LOMB PureVision aberration and improve vision and reduce halos in low illumination. MENICON Z They are a gas permeable lens manufactured with tisilfocon A. This material has excellent mechanical proper- ties resulting in a lens that is able to be designed thinner than the typical gas permeable lens. Menicon has developed a plasma treatment to make the lens more hydrophilic to aid wetting and also smooth any surface irregularities. ACUVUE OASYS These contact lenses are silicon hydrogel NEW! ACUVUE OASYSE lenses manufactured with senofilcon A with a 38% water content. They have a 2 weekly replacement schedule and available for a flexible wear modality.
