Answers to Frequently Asked Patient Questions
Are soft or GP contact lenses better?
Many patients can wear both types of contact lenses. Often patients, especially those with astigmatism and presbyopia, will find that the firmer GP lenses provide clearer, crisper vision than soft lenses. For patients with keratoconus GP lenses may be the only option for clear vision.
GP materials are a very healthy lens option since they provide excellent oxygen transmission and allow eyes to breathe. Also, because the lenses are firm they are easy to care for and last longer than soft lenses.
How long does it take to get used to GP lenses?
Adaptation to GP lenses is different for every patient and depends on eye sensitivity. Most patients who are new to contact lenses in general, or GP contact lenses more specifically, will be aware of their contact lenses at first. But, that sensation will go away after a few days to few weeks and the contact lenses will be very comfortable.
Are GP lenses an old fashioned lens technology?
Or Are GP lenses the same as hard lenses? No! GP lenses are not the same as the original “hard” lenses. In fact, GP contact lenses were introduced after soft lens technology. First launched in 1979, new generations of GP materials continue to be developed. Additionally, laboratories such as Art Optical use state-of-the-art manufacturing techniques to improve vision and comfort with their GP lens designs.
Do bifocal contact lenses work?
Yes! There are many GP bifocal and multifocal lens options that meet the needs of most patients. With a contact lens evaluation it can be determined if the patient is a good candidate. GP bifocal and multifocal lenses will meet most visual needs, however, for some tasks it may be necessary to partner contact lenses with eyeglasses.
Is it difficult to get used to bifocal contact lenses?
Getting used to bifocal contact lenses is like getting used to bifocal or progressive spectacle lenses. If the patient is wearing contact lenses for the first time, they will be aware of the lenses for a few days, but that will go away.
Can I sleep in contact lenses?
There are highly oxygen permeable lens materials that can be slept in if prescribed for this purpose by the contact lens professional. Before sleeping in any lenses patients must first be evaluated for overall eye health and tear composition to determine if they are a suitable candidate.
How does Orthokeratology work?
Orthokeratology, also known as Ortho-K, corneal reshaping, vision shaping treatment or CRT, is a non-surgical way to eliminate or reduce the need for eyeglasses or contact lenses during the day. Specially designed contact lenses are worn overnight to gently reshape the surface of the eye while the patient sleeps. In the morning after the lenses are removed clear vision generally lasts during all waking hours, thus eliminating the need for eyeglasses or contact lenses during the day.
Is Orthokeratology safe?
As long as the recommended wearing and caring schedules are followed, orthokeratology is as safe as wearing any contact lens approved for sleeping.
Do Orthokeratology lenses hurt?
Orthokeratology lenses are easy to get used to and since they are worn overnight while the patient is sleeping there is very little sensation.
Can contact lenses be worn while swimming?
No! GP lenses are susceptible to being washed out with water. Also, since water isn’t sterile there is an increased risk for eye infections.
