Bifocal contacts are available in different type of materials, such as soft and rigid gas permeable. According to replacement schedule, you can even find disposable or frequent replacement types.
With daily disposable bifocal lenses, for example, you can discard your lenses at night and wear a brand-new pair the next morning.
Types of Bifocal Contacts Materials
Multifocal contacts come in both soft and rigid materials. Bifocal soft contact lens is made of soft plastic that holds more water. Soft contacts can contain up to 79 percent water. Water is necessary to allow oxygen to reach the cornea and to make the lens comfortable to wear.
Bifocal RGP contact lens is made of breathable plastic that allows oxygen to circulate to the cornea. This lens is made of harder plastic materials that don’t contain water but allow more oxygen to pass through to the cornea than do soft lens’ material.
Bifocal soft contact lens material is more comfortable than hard contact lenses because they hold more water and thus more flexible. But for vision correction the flexibility means a drawback because they cannot keep their shape well.
Rigid gas permeable bifocal lenses, on the other hand, are able to keep their shape better when you blink resulting in a crisper vision. Vision segments of gas permeable contacts remain stable on the correct position.
There are multifocal contact lenses with silicone hydrogel materials, which have high degree of oxygen permeability and lower water content. The lens material offers health and comfort to your eyes. This material is made primarily for overnight or extended wear lens because it is found to be reducing dry eye syndrome.
