Contact Lenses Q & A
What vision problems are corrected with contact lenses?
Contact lenses are used to correct the same vision problems as eyeglasses. These problems, called refractive errors, include:
- Nearsightedness (myopia): can see nearby objects but distance vision is blurry
- Farsightedness (hyperopia): can see distant objects but close-up vision is blurry
- Presbyopia: can’t see close-up objects, so reading is difficult
You can also get toric contact lenses to correct astigmatism, a condition in which you have nearsightedness and farsightedness.
What are the different types of contact lenses?
After Dr. Ma performs a thorough eye exam and determines your level of refractive error, he talks with you about whether you’re a good candidate for contact lenses, and if so, what type of lens is best suited for your eyes.
Soft contact lenses
Soft contact lenses are popular because they’re made from comfortable silicone hydrogel that lets plenty of oxygen pass through the lens.
Gas permeable lenses
These contact lenses are rigid like hard contacts, but they let enough oxygen through to keep your eyes healthy.
Hybrid contact lenses
Hybrid lenses are made with a gas-permeable center that’s surrounded by a soft material.
What specialized contact lens options are available?
When you make a decision about contact lenses, you’ll also talk with Dr. Ma about customized lenses such as:
Disposable contact lenses
Most types of contact lenses must be regularly and thoroughly cleaned to prevent the build-up of bacteria or other substances that can cause an infection or irritate your eye. With disposable lenses, you don’t need to worry about cleaning.
Disposable contacts are discarded and replaced every day, every two weeks, or monthly, depending on the type.
Extended-wear contact lenses
If your eyes are healthy, and Dr. Ma determines you’re a good candidate, you may be able to get extended-wear contact lenses. You can wear these contacts continuously, including while you sleep, for 7-30 days, depending on the brand.
Bifocal contact lenses
Just like bifocal eyeglasses, these contacts are made with one zone to correct for distance vision, while the other corrects close-up vision.
Dr. Ma also offers specialty contacts, such as:
- Color contacts to change your eye color or camouflage color irregularities
- Sports contacts to reduce glare and filter sunlight
- Keratoconus contacts to correct problems caused by a thinning, cone-shaped cornea
If you’d like to get contact lenses, the first step is to schedule an eye exam. Call Bryan Ma, O.D. Optometry, or book an appointment online.
