In simple terms, checking refraction is often called "checking the number." A refractive error occurs when the shape of your eye prevents light from focusing correctly on the retina, resulting in blurred vision.
Common types of refractive errors include:

• Myopia (minus number)
• Hypermetropia (plus number)
• Astigmatism (cylinder number)
• Presbyopia (age-related "after 40" number)

Accurate measurement of these errors is essential for prescribing glasses, contact lenses, or planning cataract lens implants or LASIK surgery.

We use a Topcon autorefractor, a compact and advanced machine that:

• Automatically measures the refractive error of the eyes.
• Allows the examiner to observe the patient's facial expressions during the test.
• Offers a tiltable design for a more natural head position, improving comfort.
• Provides faster results, making the examination smoother and more patient-friendly.

This efficient and precise technology helps ensure that your corrective prescription is accurate and tailored to your individual visual needs.
