A contact lens fitting is a specialized eye exam that helps find the right lenses for your eyes. Unlike a standard eye exam that checks your vision and eye health, a fitting measures the shape, size, and surface of your eyes. At Insight Vision Optometry in Spring Valley, our eye doctors use these measurements to choose lenses that sit properly on your eyes. A good fit means clearer vision and better comfort throughout the day.
Approximately 45 million people in the United States wear contact lenses (CDC, 2024). Each one of those wearers needs a proper fitting to make sure their lenses are safe and comfortable. Whether you are trying contact lenses for the first time or updating your current prescription, a fitting is an important first step.
Contact lenses are not one-size-fits-all. A lens that fits one person well may cause problems for someone else. Lenses that are too tight can reduce oxygen flow to the cornea. Lenses that are too loose may move around and blur your vision. A professional fitting helps prevent these issues before they start.
Poor-fitting lenses can lead to discomfort, redness, and even eye infections over time. More than 80 percent of contact lens wearers practice at least one risky behavior that raises their risk of eye infections (CDC, 2017). Regular fittings and follow-ups can help reduce these risks and keep your eyes healthy.
Anyone who wants to wear contact lenses should have a fitting before starting. This includes first-time wearers, people switching lens types, and those whose prescription has changed. Patients with astigmatism, dry eyes, or irregular corneas may need more detailed fittings to find the right lens design.
Children and teens who are interested in contact lenses also need a proper fitting. Our eye doctors can help determine whether a young patient is ready for the responsibility of wearing and caring for contact lenses.
The first part of a contact lens fitting involves measuring the shape and curvature of your cornea. Your eye doctor uses a keratometer to measure the curve of the front surface of your eye. In some cases, a detailed corneal map may be created using advanced imaging technology. These measurements help determine the right base curve and diameter for your lenses.
Your pupil size and the distance between your eyelids are also measured. These details affect how the lens centers on your eye and how it moves when you blink. Accurate measurements are key to finding a lens that stays in place and provides clear vision.
Your tear film plays an important role in contact lens comfort. During the fitting, your eye doctor checks the quality and quantity of your tears. A healthy tear film helps the lens glide smoothly on the eye surface. If your tears are thin or dry out quickly, your doctor may suggest lenses made from materials that hold moisture better.
Your eye doctor also examines the overall health of your cornea and the surrounding tissues. This exam helps identify any conditions that could affect your ability to wear contact lenses safely. Addressing these concerns early leads to better outcomes and more comfortable wear.
After measurements are taken, your eye doctor places a trial lens on your eye. This allows them to see how the lens fits, moves, and centers on your cornea. The lens should move slightly with each blink but stay centered over the pupil. Your doctor uses a slit lamp microscope to check the fit closely.
You may try several different lenses during this part of the appointment. Your feedback about comfort and vision clarity helps your doctor fine-tune the prescription. Once the right lens is found, you will receive a prescription with your lens power, base curve, and diameter.
Soft lenses come in several replacement schedules. Daily disposable lenses are worn once and discarded at the end of the day. Bi-weekly and monthly lenses are cleaned and stored each night. Our optometrists can help you choose the schedule that works best for your lifestyle and eye health needs.
Patients over 40 who have trouble focusing on close objects may benefit from multifocal contact lenses. These lenses have different zones for near, intermediate, and distance vision. Fitting multifocal lenses takes a bit more time because your doctor needs to balance clarity at all distances.
Our team will determine whether a specialty lens is the right choice based on your eye health and vision needs. The fitting process for specialty lenses may involve additional measurements and follow-up visits.
If you are new to contact lenses, your eye doctor will teach you how to insert and remove them safely. This hands-on training is an important part of your fitting appointment. Most patients learn the technique within 15 to 30 minutes. Your doctor will make sure you feel confident before you leave the office.
It is normal to feel a little nervous at first. Your eyes have a natural reflex to close when something comes near them. With practice, inserting and removing lenses becomes a quick and easy part of your daily routine.
Most new contact lens wearers need a short adjustment period. Your eyes may feel slightly dry or sensitive for the first few days. This is normal and usually improves as your eyes adapt to the lenses. If discomfort continues beyond the first week, reach out to your eye doctor for advice.
Your doctor may schedule a follow-up visit within one to two weeks of your fitting. This visit allows them to check how the lenses are performing and make any needed adjustments. Early follow-ups help catch minor issues before they become bigger problems.
Starting with a shorter wearing time can help your eyes adjust more comfortably. Your doctor may suggest wearing lenses for a few hours on the first day. You can then increase wear time gradually. Keeping your hands clean before handling lenses reduces the risk of transferring bacteria to your eyes.
Here are some helpful habits to develop from the start.
Proper lens care is one of the most important things you can do to protect your eye health. If you wear reusable lenses, clean and rinse them with fresh solution every time you remove them. Do not use tap water or saliva to clean your lenses. These can introduce harmful bacteria and organisms to your eyes.
Replace your lens case at least every three months. Old or dirty cases can harbor bacteria even if your solution is fresh. Let your case air dry upside down after each use to reduce the chance of contamination.
Following your recommended replacement schedule is essential for safe lens wear. Wearing lenses beyond their intended lifespan can cause protein and lipid deposits to build up. These deposits can reduce comfort and increase your risk of infection. Your eye doctor will tell you how often to replace your specific type of lens.
Annual follow-up exams are important even if your lenses feel fine. Our eye doctors check for early signs of problems that you may not notice on your own. These visits also ensure your prescription is still accurate and your eyes remain healthy.
Knowing when to stop wearing your lenses can protect your eyes from serious harm. Remove your lenses right away if you notice redness, pain, unusual discharge, or sudden changes in vision. These symptoms could indicate an infection or other condition that needs prompt attention.
Research shows that about 1 in 500 contact lens wearers develops a serious eye infection each year (CDC, 2024). While this number is relatively small, acting quickly at the first sign of trouble can make a real difference in protecting your vision.
Many children and teens can wear contact lenses with proper guidance and supervision. There is no strict minimum age for contact lenses. Your eye doctor will consider the child's maturity, hygiene habits, and motivation when deciding if they are ready. Studies suggest that children as young as eight can handle daily disposable lenses responsibly.
Contact lenses can be a practical choice for young athletes or children who find glasses uncomfortable during activities. Families in Spring Valley trust our team at Insight Vision for thorough pediatric contact lens fittings.
Myopia, or nearsightedness, is becoming more common among children worldwide. Specialty contact lenses for myopia management can help slow the progression of nearsightedness in growing eyes. These lenses change how light focuses on the retina. This approach may help reduce how quickly myopia worsens.
Our eye doctors can determine whether myopia management lenses are a good fit for your child. Regular follow-up visits are especially important for young patients wearing these specialty lenses. Monitoring ensures the lenses continue to fit well and work as intended.
An annual contact lens exam is about more than just checking your prescription. Your eye doctor examines the health of your cornea and looks for any signs of wear-related stress. Contact lenses sit directly on your eyes, so regular monitoring helps catch subtle changes early. The American Optometric Association recommends yearly exams for all contact lens wearers (AOA, 2023).
Skipping annual exams can lead to problems that go unnoticed until they become more serious. Early detection of issues like corneal thinning or blood vessel growth allows for timely treatment. Consistent follow-up care helps you enjoy contact lenses safely for years to come.
Your vision and eye health can change from year to year. An updated fitting ensures your lenses still match the current shape and needs of your eyes. Changes in your prescription, tear film, or overall eye health may call for a different lens type or wearing schedule.
Our optometrists at Insight Vision stay current with the latest lens materials and designs. If a newer option might offer better comfort or clearer vision, our team will let you know. Patients throughout Spring Valley count on us for expert contact lens fitting and follow-up care.
