When understanding your vision, a refraction test is the cornerstone of any comprehensive eye exam. Think of it as the “tuning” of your prescription: it helps your eye doctor pinpoint exactly how your eyes focus light so that you can see the world in crisp, precise detail. At M&M Eye Institute, we believe that demystifying these tests empowers you to take control of your eye health and keeps you confident that you’re getting the help you need.
What Is The Purpose of a Refractive Test?
A refraction test measures how light bends (or “refracts”) as it enters your eye. During the exam, your doctor will present a series of lenses and ask, “Which is clearer—one or two?” We determine your precise eyeglass or contact lens prescription by comparing how different lens powers sharpen your vision.
Why do we do it?
- Correct nearsightedness & farsightedness: Identify whether you need plus (+) or minus (–) corrective power.
- Spot astigmatism: Detect irregular curvature in your cornea that causes blurred or distorted vision.
- Track prescription changes: This will ensure ongoing comfort and performance in your everyday life—whether behind the wheel, at your desk, or playing with the kids.
-
Spot Presbyopia: This happens when the eye’s natural lens loses flexibility, usually starting in your 40s.
-
Anisometropia: Significant difference in refractive power between the two eyes. It can cause symptoms like eye strain, headaches, or double vision.
What to Expect During Your Test
1. Pre-Check
We use an eye chart to measure visual acuity (how well you see at different distances).
2. Lens Comparison
Sitting behind a phoropter (that gadget with all the lenses), you’ll compare two options: “One or two?” until we zero in on your best focus.
3. Fine-Tuning
We may use a handheld device (retinoscope) or a digital refractor to double-check your prescription.
Prescription & Recommendations
Once we’ve nailed your numbers, we’ll discuss lens types (standard, high-index, progressive), coatings (anti-glare, blue light), or contact lens options tailored to your lifestyle.
Frequently Asked Questions (FAQ)
1. How often should I get a refraction test?
We generally recommend adults have one every 1–2 years, or sooner if you notice changes in vision, headaches, or eye strain. Kids and those with certain health conditions may need exams more frequently.
2. Does a refraction test hurt?
Not at all! It’s completely painless. You’ll indicate which lens makes the chart look sharper—no poking or prodding involved.
3. How long does the test take?
Plan for 10–15 minutes for your overall eye exam. It’s quick, but the clarity it brings lasts all year.
4. Can I bring my current glasses or contacts?
Absolutely. Bring them along so we can compare and see how your eyes are performing with your existing prescription.
5. Will insurance cover it?
Most vision plans include coverage for refraction testing as part of a standard eye exam. We’ll help you verify benefits before you come in.
