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 and 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?
Are GP lenses an old lens technology? Or are they the same as hard lenses?
Adaptation to GP lenses is different for every patient and depends on eye sensitivity. In general, most patients who are new to wearing contact lenses, or specifically, new GP contact lenses wearers, are able to feel their contact lenses initially. Nonetheless, that sensation will disappear after a few days to few weeks and the wearing experience will be normal.
No! GP lenses are not the same as the original “hard” lenses. In fact, GP contact lenses were introduced after soft lens technology. Since its first launched in 1979, GP materials continue to develop. For example, GP lenses has been increasing its oxygen transmission while maintaining good wetting and deposit resistance, and increasing stability and durability without compromising corneal physiology. Additionally, laboratories such as Oculus & Art Optical use state-of-the-art manufacturing techniques to improve vision and comfort with their GP lens designs.
Do multi-focal contact lenses work?
Is it difficult to get used to multi-focal contact lenses?
Yes! There are many GP multifocal lens options that meet the needs of most patients. The patient can be determined if he/she is a good GP multi-focal lens candidate through a contact lens evaluation. GP multifocal lenses will meet most visual needs. However, it may be necessary to partner contact lenses with eyeglasses when doing certain tasks.
Getting used to multi-focal 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 able to feel the lenses for a few days. Nevertheless, that sensation will go away eventually.
Can I sleep in contact lenses?
How does Orthokeratology work?
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.
Orthokeratology, also known as Ortho-K, is used for corneal reshaping or vision shaping treatment. It 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 surface of the eye while the patient sleeps. After the lenses are removed the next day, clear vision generally lasts during all waking hours and eliminate the need for eyeglasses or contact lenses during the day.
Is Orthokeratology safe?
Do Orthokeratology lenses hurt?
As long as the recommended wearing and caring schedules are followed, orthokeratology is as safe as wearing any contact lens approved for sleeping.
Orthokeratology lenses are easy to get used to. Since they are worn overnight while the patient is sleeping, there is minimum lens sensation.
Can contact lenses be worn while swimming?
No! GP contact lenses are susceptible to being washed out with water. Furthermore, when the water is not sterile, there is an increased risk for eye infections.
