accuvue bifocal contacts

(Lenses made from polycarbonate, the same type of plastic used for the space shuttle windshield, are about 50 times stronger than other lens materials.) Also, people at risk of receiving electric shock should avoid metal frames.People accuvue and bifocal employed in certain occupations may be prohibited from wearing contact, or may be required to wear safety eyewear contacts over the contact.

Disposable lenses may also help to prevent infection, since the wearer is guaranteed a clean pair of lenses every few weeks or every day contacts.
