How Glasses Correct Common Vision Problems: Myopia vs. Hyperopia

Glasses are carefully designed to correct how light enters your eyes, compensating for the way your eyes naturally bend (or refract) light. Two of the most common refractive errors are myopia (nearsightedness) and hyperopia (farsightedness), and glasses play a crucial role in balancing each condition to restore clear, comfortable vision.
 

Understanding How Vision Works

Your eyes focus light onto the retina - a thin layer of tissue at the back of the eye - to create a clear image. Ideally, light rays converge exactly on the retina. When they focus in front of or behind it, vision becomes blurry. That’s where prescription lenses step in, bending light before it enters your eye so it lands precisely where it should.
 

What Is Myopia?

Myopia occurs when the eye is too long or the cornea (the front surface of the eye) is too curved. This causes light to focus in front of the retina instead of directly on it, making distant objects appear blurry while nearby objects remain clear.
 

Lenses for myopia are concave - thinner in the center and thicker at the edges. These lenses diverge light rays slightly before they enter the eye, shifting the focal point backward so that it falls perfectly on the retina. This adjustment allows myopic wearers to see distant objects clearly again, restoring balance to their visual experience.
 

What Is Hyperopia?

Hyperopia is the opposite of myopia. It happens when the eye is too short or the cornea is too flat, causing light to focus behind the retina. People with hyperopia can often see distant objects more clearly, but struggle to focus on nearby tasks such as reading or using a phone.
 

Lenses for hyperopia are convex  - thicker in the center and thinner at the edges. These lenses converge light rays before they enter the eye, bringing the focal point forward onto the retina. This helps the eye focus more efficiently on close-up objects, easing strain and improving clarity at all distances.
 

Optical Precision Matters

At GV Optical, precision lens crafting is at the heart of what we do. Every prescription is measured to the exact curvature and distance your eyes require.
