Glasses, that is what most people expect when they visit the eye doctor. When visiting the eye doctor, most people expect to sit in the exam chair, read the wall chart and leave with a prescription for new frames. But what if you want to trade those frames for contact lenses? You might assume your standard checkup is all you need.
It is not.
While a routine visit checks your basic eye health and determines your eyeglasses prescription, a contact lens exam goes much further by measuring the unique curves of your eye to ensure a safe, exact fit. At Vision 2C, Dr. Marianna Konradi and our team want you to know exactly what happens before you sit in our exam chair. Getting this right is very important.
What Happens During a Regular Eye Exam?
A standard eye check is your first step for great vision. Think of it as a basic physical, but just for your eyes. The doctor evaluates your near and distance vision and examines the internal structures of your eyes to ensure overall ocular health.
Here is what you can usually expect during a normal visit:
- Reading a chart full of letters to see how sharp your vision is.
- Looking into bright lights so the doctor can check the inside of your eyes.
- Testing for hidden problems like glaucoma or dry spots that you might not even feel yet.
- Checking your side vision to make sure you can see things out of the corner of your eye.
- Shining a light to see how your pupils react.
- Figuring out the exact prescription number you need to buy glasses.
Upon completing this visit, you will receive a written prescription for eyeglasses only. This small difference in distance matters in the calculation because glasses sit on your nose, while contact lenses sit right on the surface of your eye. So, you need an entirely different prescription to see clearly in contacts.
Why You Need a Special Contact Lens Exam
Because contact lenses rest directly on your eyes, they demand a precise fit. A poor fit is not just uncomfortable, it can actually cause corneal scratches or lead to painful infections.
That is exactly why the friendly team at Vision 2C always performs extra tests. Because no two eyes are the same, ranging from steep to flat, or perfectly round to slightly oval, we must precisely measure the size and shape of your eyes to find an exact match. (Yes, even your left and right eyes can be completely different shapes!) This is the only way to make sure you stay comfortable from morning until night.
Your lifestyle matters too. Dr. Konradi will ask about your daily habits, such as your screen time, outdoor activities and whether you prefer daily disposable or extended-wear lenses. Your answers help the doctor pick the safest lens material for your busy life.
Key Steps in a Contact Lens Exam
When you visit Vision 2C’s offices in Brewer or Thomaston for contacts, we add extra steps. These steps keep your eyes safe and happy.
- Measuring the Clear Front of Your Eye: Your doctor will use a specialized machine to map the surface of your cornea, the clear window at the front of your eye, to determine the optimal curve for your new lenses.
- Checking Your Pupil Size: We measure the dark circle in the middle of your eye. This measurement is critical, especially if you require specialized lenses for reading or astigmatism.
- Testing Your Tears: Because contact lenses act like tiny sponges that require moisture to stay soft, we evaluate your tear production to ensure your eyes can keep the lenses comfortably hydrated all day.
- Trying on Trial Lenses: While you are still in the office, we will apply a diagnostic pair of lenses and observe their movement as you blink to ensure they settle correctly.
- Checking Your Comfort: We will also ask you how they feel. If they rub or pinch, we will remove them and try a different pair until we achieve the optimal fit.
The Final Contact Lens Prescription
Once we find the optimal fit, you will receive a contact lens prescription containing specific measurements not found on a standard glasses prescription.
Your new contact lens prescription will list these exact details:
- The base curve: This matches the exact slope of your eye so the lens hugs it perfectly.
- The diameter: This tells us how wide the lens needs to be to cover your eye.
- The brand and material: Your doctor picks the exact type of lens that works best for your natural tears.
- The expiration date: This keeps you safe. It makes sure you get your eyes checked again next year.
You need every single one of these details. Without them, you cannot buy contact lenses safely from any store or eye clinic. The brand matters just as much as the numbers do.
Conclusion
Eye exams are important for eye health. They give you vision with glasses. A contact lens exam, however, is to make sure your lenses fit well, feel comfortable all day long and protect your sensitive eye surface from damage.
If you’re interested in switching from glasses to contacts, you will need to have both exams. They work as a team. One is to protect your overall eye health. The other protects the delicate surface of your eye.
Eye care doesn’t have to be complicated. Vision 2C’s experts focus on your vision clarity, comfort and safety. Call us at (207) 200-1492 or book your appointment online today to arrange your exam. We’ll assist you in selecting the ideal contact lenses for your eyes.
FAQs
Q. Why do contacts need a special fit?
Every eye has a different shape. If a lens fits badly, it can scratch your eye. It can also cause a very painful sore. A perfect fit keeps you safe.
Q. How is a glasses exam different from a contacts exam?
A glasses exam checks your eye health. It gives you the numbers you need for glasses. A contacts exam measures your exact eye shape. This ensures the little lenses fit securely and tightly.
