If you have just been diagnosed with presbyopia but bifocal glasses are definitely not your type today’s technology has the answer for you: bifocal contact lenses. Bifocal contacts come as the other types of contacts in various types. They can be disposable soft lenses or made out of rigid gas permeable materials.

Alternative bifocal lenses

Just like bifocal glass lenses, bifocal contacts have two powers (prescriptions) in the same lens. When you wear them your eye switches from one power to the other according to the focus of your vision: long distance or near distance. These types of lenses are called alternative bifocal lenses.

The way the alternations can take place is only through the unique construction of the contact lens. Unlike the glass bifocal lens where you merely shift your vision focus and the lens stands still, contacts stay on top of your eye and hence move with any eye movement. To accommodate for this feature, alternative bifocal lenses have a smaller size that regular contacts, which allows them to stay right above the lower eyelid. When you will look downward the lens will be able to stay in place and hence correct your vision impairment.

Simultaneous vision lenses

Unlike alternative bifocal lenses, simultaneous vision lenses allow gaze to be directed through distance and near powers at the same time. Without needing to look through different focus points these lenses can actually work only because our complex optical system learns through trial and error which power to choose according to the distance at which you are trying to see objects.

These various options allow you to choose the type of bifocal lens you seem fit for your needs and tastes. Regardless of your choice, you can be sure that today’s technology is the solution for an inconvenient vision condition, allowing you to continue your lifestyle incomplete visual comfort.
