Contact Lens FAQ
Our Spartanburg Optometrist Answer Your Contact Lens Questions
If you're new to the world of contact lenses, you may be confused by the sheer range of options available. Here are answers to some frequently asked contact lens questions from our Spartanburg SC optometry team at Eyes on Henry.
- Who should consider contact lenses? Contact lenses can make a fine choice for most adults and older children with refractive errors. They're especially useful for people with active or sporty lifestyles.
- What conditions or situations might make it harder for me to wear contact lenses? "Hard to fit" conditions may include dry eye, giant papillary conjunctivitis (a sensitivity to proteins deposited on the lens), previous LASIK or other eye surgery, a deformation of the cornea called keratoconus, and refractive errors such as astigmatism or presbyopia.
- How does my Spartanburg SC optometrist determine my contact lens needs? Your Spartanburg SC optometrist will administer a contact lens exam to measure your corneal contours, pupil size and iris diameter. You'll also be asked about any underlying conditions or lifestyle preferences you may have that might call for specific contact lens options.
- What are GP contact lenses? "GP" stands for "gas permeable." These lenses are made from a special breathable plastic that allows oxygen to reach the eye for long-term safety and comfort. Since they are rigid enough to hold their shape constantly, they are also called rigid gas permeable (RGP) lenses.
- Why might I choose GP lenses over soft lenses? GP lenses have superior optical qualities compared to standard soft lenses; this makes them a better choice for complex refractive errors and stronger prescriptions. They’re also less likely than soft lenses to accumulate protein deposits and other irritants.
- What are toric contact lenses? Toric contacts are made to fit the cornea precisely in one position, with no rotating or sliding. This is critical for astigmatism because the correction must align itself with the specific areas of deformation.
- What are scleral contact lenses? Scleral contacts are oversized lenses that extend to the white of the eye, or sclera. Since they can vault completely over corneal deformations, they do an excellent job of correcting kerataconus and complex refractive errors. They also provide a moisture reservoir for dry eye patients.
- I have presbyopia. Can contact lenses correct my vision? Multifocal contact lenses can correct your presbyopia just as easily as multifocal eyeglasses can. Since presbyopia calls for vision correction in two or more distance ranges, multifocal contacts include different correction levels arrange in concentric rings or separate areas on the lens. If you prefer, you can also get monovision lenses that correct for a single distance range in each eye.
