What is Refraction in an Eye Exam? 
Discover the importance of refraction in eye exams, how it affects your vision, and why A New Vision in Beaverton, OR, stands out in optometry care.

Understanding Refraction

Refraction, in its simplest terms, refers to the bending of light. Just like a straw appears bent when placed in a glass of water, light bends when it moves from one medium to another. Within the context of our eyes, refraction happens when light transitions from the air into the gel-like substances of the cornea and lens. The goal of this process is to focus light rays directly onto the retina. The retina then transforms these light rays into impulses that the brain interprets as images. Precise and optimal refraction is the basis for clear, sharp vision.

Why is Refraction Important?

Refraction is the very foundation of our ability to see clearly. If light doesn't focus perfectly onto the retina, it causes refractive errors. These are not eye diseases but are, in essence, vision problems that can cause blurred vision and other symptoms. Common refractive errors include:

• Myopia (nearsightedness): Objects far away appear blurred while close objects can be seen clearly.
• Hyperopia (farsightedness): The opposite of myopia, distant objects are clearer than close ones.
• Astigmatism: Causes blurred vision at any distance due to an irregularly shaped cornea or lens.
• Presbyopia: An age-related condition where the eye's lens becomes less flexible, making it challenging to focus on close objects.

The Refraction Test 

A central part of your eye exam is the refraction test. It's the process through which optometrists determine the lens power you'd need to see clearly. Here's a more in-depth look:

1. The Phoropter: This is an instrument filled with different lenses. As you look through it, you'll be presented with a series of lens choices.
2. Fine-Tuning Vision: Your optometrist will switch between lenses, asking which one makes your vision clearer. It's a meticulous process, ensuring your prescription provides optimal clarity.
3. Beyond Clarity: The test isn't just about sharpness. Your doctor assesses your visual comfort and how your eyes work together, ensuring you not only see clearly but also comfortably.
