Why can’t I see distance with multifocal contacts? One of the most frequently asked questions in clinic is why multifocal contacts are blurry in the distance.

Are multifocal lenses worth it?
Newer multifocal lenses had statistically significantly better outcomes than older diffractive lenses or refractive lenses, when compared to monofocal IOLs, in near vision, quality of vision, and risk of halos.
How long can you wear RGP lenses in a day?
Fitting Considerations I recommend that patients be successfully fit in daily wear RGP lenses for at least four weeks before considering them for extended wear. Successful daily wear should constitute a minimum of 10 hours per day asymptomatic wearing time with no signs of corneal compromise.

The lenses are usually fitted as daily wear lenses and if the eyes show no sign of ill effects, overnight wear is commenced. Rigid gas permeable (RGP) lenses are also used for overnight wear in some circumstances.
Can RGP lenses damage eyes?
Because of its incomplete oxygen permeability, RGP contact lens can reduce the use of oxygen in corneal tissue. Hypoxic damage caused by long-term wear of RGP contact lens can affect the morphological and biological characteristics of the cornea.
How often should RGP contacts be replaced?

Can RGP lenses fall out?
Your contact lenses can fall out for a variety of reasons, including improper fit and rubbing your eyes too vigorously. For the record, your contacts should stay in place until you remove them on your own. “It’s not normal for contacts to fall out,” Alisha Fleming, O.D., an optometrist at Penn Medicine, tells SELF.

These contact lenses might be helpful if you’ve tried soft contact lenses and have been unsatisfied with the results or if you have “dry eyes.” Rigid gas permeable contact lenses are more durable than soft contact lenses.
Why do I see blurry with multifocal contacts?
Many presbyopes experience a hyperopic shift due to decreasing index of refraction in the lens, exacerbating their presbyopic symptoms. Use the most plus or least minus prescription to maintain clear distance vision while maximizing the benefits of the multifocal.
How long does it take your eyes to adjust to multifocal contacts?
It may even take from four to six weeks for their eyes to adjust. Set the first follow-up appointment for one week and make adjustments as needed. Near visual acuity is not always a good predictor of success with multifocal contact lenses.
