What is the difference between bifocals and Multifocals?

Bifocal contacts lenses (like bifocal eyeglass lenses) have two powers – one for seeing clearly far away and one for seeing clearly up close. Multifocal contact lenses, like progressive eyeglass lenses, have a range of powers for seeing clearly far away, up close and everywhere in between.

What are multifocal used for?

According to the National Eye Institute, multifocal contact lenses are used for correcting both myopia (poor far vision) and presbyopia (poor near vision). Ideally, these contacts will help with close-range tasks like reading, as well as tasks involving distance vision, like driving.

Who needs multifocal lenses?

Multifocal lenses are typically prescribed for adults over age 40 to compensate for a common condition called presbyopia (explained further below). Multifocal lenses are also the lenses of choice for some children and young adults who have eye teaming or focusing problems that cause eyestrain when reading.

How long does it take to get used to multifocal?

four to six weeks
Plan for four to six weeks to get used to them. Over time, your eyes will naturally look through the correct part of the lens, and you’ll enjoy better vision because of it. Another problem with multifocal contact lenses is that you might see glare for a while during the darker hours of the day.

Is multifocal the same as trifocal?

Unlike bifocal multifocal IOLs, which split light in two ways to give near and distance vision, trifocals split light three ways to provide an intermediate focal point, typically around 80 cm (about 31 inches).

Are multifocal cataract lenses worth it?

Existing systematic reviews have generally concluded that multifocal IOLs result in better uncorrected near vision and greater spectacle independence, but more unwanted visual phenomena such as glare and halos, compared to monofocal IOLs.

Do you have to wear Multifocals all the time?

Myth 1: Sometimes people fear that wearing multifocals means wearing glasses all the time – but that’s not true. Even people who only need glasses for close up – reading, ipad, phone and computer – can wear multifocals for these activities, and then take them off when finished.

Are Multifocals hard to get used to?

The most common is a set of concentric circles of lenses prescribed for different viewing distances. There are also blended designs, which mimic a natural viewing experience. Getting used to multifocal contact lenses can be difficult for some people and can take some time to adjust.
