Getting a new prescription for is important to ensure we capture an accurate measurement of your vision needs. At our clinic, our contact lens specialists in Houston will evaluate your eyes to determine the best solution, whether custom made contact lenses or standard soft lenses are the best solution for your needs.
An eyeglasses prescription is a helpful guide for a contact lens prescription, but we measure the variation in shape of each patient’s eyes for a contact lens prescription. Identifying the necessary lens power to correct a patient’s farsightedness or nearsightedness is the primary purpose of updating a contact lens prescription.
Other variations in the eye’s shape are also important for a good fit.
Differences between your left and right eyes sometimes require bifocal contact lens. These multifocal contacts simultaneously correct two refractive errors in a patient’s eyes. Sometimes bifocal contacts are too uncomfortable or don’t provide clear vision, so we prescribe monovision contacts. These contacts split the error correction between the left and right eyes.
Irregular cornea curvature can worsen an already-bad prescription by ineffectively spreading light onto the retina. Corneas like these require corrections for astigmatism or keratoconus (the latter in more severe cases).
With a copy of your prescription, you can also ask for an eyeglasses prescription.
However, not all contacts are of the same quality. Technological advances in contact lens manufacturing and efficacy have created possibilities for many different contact lens types. Those types can vary by the materials used or the functional design.
