Contact lenses are a popular form of corrective eyewear and are a great alternative to glasses. While contacts are convenient and comfortable for most people, certain eye health conditions can make contacts difficult to wear. Some conditions make patients hard to fit for contacts and require specialty lenses. At Livermore Optometry Group, serving Livermore, Dublin, and Pleasanton, CA, our optometrist provides a variety of hard to fit contacts. We will perform an eye exam and contact lens exam to determine what lenses are best for your condition.
What Are Hard to Fit Contacts?
Hard to fit contacts are different from traditional contacts. There are several eye conditions that make you hard to fit for contacts. Keratoconus, for example, occurs when your eye is more cone-shaped than round. Traditional contacts will not fit your eye, so you will need a specially shaped lens. Other conditions include dry eye, presbyopia, giant papillary conjunctivitis, astigmatism, and corneal scarring.
Contact Lens Exams
If you want to wear contacts, you will first need a contact lens exam. During this, our optometrist will evaluate your vision with different lenses to determine your prescription. We will ask you to look at lines of letters via a magnifying device, changing the magnifying power until you find which one allows you to see the lines clearest.
We will also measure your eye surface and perform a tear film evaluation to see if your eyes are properly lubricated. If our eye doctor notices any abnormalities, you might be hard to fit for contacts.
Depending on your condition, we will perform several other tests, including measuring your cornea, to see which specialty contacts will be most comfortable for you. You can test out the lenses for several days to ensure that they work.
Hard to Fit Lenses
There are several specialty lenses that work for different eye conditions. Toric lenses have a unique shape that works well for patients with astigmatism. These lenses are typically custom-made.
Scleral lenses are also hard to fit lenses. These lenses sit on the whites of your eyes, as opposed to your cornea. They vault over an irregularly shaped cornea, making them a good option for keratoconus. They can also work for dry eye because they hold more moisture.
Rigid gas permeable lenses hold their shape more than traditional lenses and can also work with keratoconus. They are also a good option for dry eye and giant papillary conjunctivitis.
For presbyopia, patients may need bifocal or multifocal lenses with several prescriptions.
