What is the difference between myopia and hyperopia

What is the difference between myopia and hyperopia?

In the previous article, we discussed “How do you tell if glasses are too big for your face?”. In this article, let’s talk about “What is the difference between myopia and hyperopia?”.

Different Definition

The lens and ciliary muscles help us see near and far. When you look at something far away, the ciliary muscles stretch the lens and reduce the focus to make the object clearer. When the object is closer, the ciliary muscles compress and increase the focus. When light falls on the lens, it converges on the retina to form an inverted image. Myopia is the most common refractive eye disease in the world, and people with myopia usually can clearly see nearby objects, like books and digital screens. However, objects that show in the distance look blurry. People with farsightedness can see objects in the distance clearly, while those objects close to their faces are blurred.

Different Reasons

Myopia is caused by the refraction of the cornea, which increases the distance between the lens and the retina, allowing light to converge in front of the retina. Myopia is because the eyeball has grown too long relative to its ability to focus. In farsightedness, the eyeball is too short and the focus falls behind the retina. It forms an image behind the retina, causing light to be refracted behind the eyeball.

They happen at different times.

Symptoms of myopia usually begin in childhood, but can occur at any age. Hyperopia is usually present at birth and tends to run in families.

Different Treatments

Prescription lenses are the most common and successful treatment for refractive errors, including nearsightedness and farsightedness. Hyperopia, or nearsightedness, increases your risk of certain eye diseases, including glaucoma, cataracts, and macular degeneration. Myopia can be treated with a concave lens of appropriate focal length. Early pseudomyopia can be restored by proper outdoor exercise, more looking into the distance, and reducing excessive use of the eyes. Once it is determined to be true myopia, you can correct your eyesight by wearing glasses. If the degree of myopia is relatively high, you can consider the treatment of laser surgery. Hyperopia can be treated by using a convex lens of appropriate focal length. Cooperating with rehabilitation training to improve vision, avoid visual fatigue, and avoid fatigue. Go to the hospital for regular check-ups. Blink a lot to keep germs out.
