Our eyes come in many shapes and sizes, and these variations can sometimes make fitting contact lenses a more complex process. Factors such as corneal curvature, eye dryness, and individual lifestyle needs all play a role in determining the right type of contact lens. If you’re searching for eye care near you in Santa Clara, CA, consider visiting our team at Silicon Valley Eyecare Optometry and Contact Lenses.
Why Contact Lenses Can Be Hard to Fit
Fitting contact lenses is not always straightforward. Challenges may arise due to:
- Corneal Shape and Curvature: Irregularities in the cornea's shape can make standard lenses unsuitable.
- Pupil and Iris Size: Differences in pupil and iris size require precise lens sizing to ensure proper fit and comfort.
- Dry Eyes: Insufficient tear production or poor tear quality can make wearing traditional contact lenses uncomfortable.
- Lifestyle Needs: Certain materials or types of lenses may be better suited for specific activities or work environments.
These factors mean some individuals may need specialized contact lenses and more precise measurements to achieve the best fit.
The Contact Lens Exam and Fitting Process
A successful contact lens fitting starts with a thorough eye exam and precise measurements. For those with unique needs, additional steps may be required:
1. Corneal Shape and Curvature: Optometrists use devices like a keratometer or corneal topographer to measure the shape of your cornea. These tools reflect light off the surface of your eye to provide detailed data.
2. Pupil and Iris Size: The size of your pupil and iris is measured using a ruler or an automated device to ensure the selected lenses match your eye's dimensions.
3. Tear Film Evaluation: A small paper strip placed under the lower eyelid evaluates the quantity and quality of your tears. This helps determine if you may need specialty lenses, such as scleral lenses, to manage dry eyes.
4. Lens Trials and Fitting: Based on these tests, your optometrist will recommend several lenses for you to try. After testing these for comfort and clarity, you’ll take the best-fitting pair home for a trial period of one to two weeks. If the lenses perform well, they will become your prescribed lenses. Otherwise, adjustments or additional trials may be necessary.
