What is ametropia

Ametropia is an ophthalmic disease in which the cornea and lens of the human eye can not focus light on the retina correctly, resulting in blurred vision. Common refractive errors include myopia, hyperopia, astigmatism and presbyopia.

Myopia refers to that the eye can see clearly when looking at objects near, but can not see clearly objects far away. This is because the eyeball of myopia is relatively long, and the light is focused in front of the retina rather than on it.

Hyperopia refers to that when the eye looks at objects in the distance, it can see clearly, but it can't see objects near clearly. This is because the eyeball of hyperopia is relatively short, and the light is focused behind the retina rather than above it.

Astigmatism means that the curvature of the cornea or lens is uneven, resulting in the inability of light to focus into a point in the eye, resulting in blurred vision.

Presbyopia refers to the gradual hardening of the lens with age, which affects the ability of the eye to regulate objects in close proximity. This leads to the need to pull a long distance when people look at objects near them to obtain clear vision.

How to correct ametropia

The most common way to correct refractive errors is to use glasses or contact lenses. According to the advice of ophthalmologists, wearing glasses or contact lenses of appropriate degree can help correct ametropia and improve vision.

In addition, people can also choose to correct ametropia through vision correction surgery. Common surgical methods include laser myopic surgery, lens implantation and refractive lens implantation. These operations can correct refractive errors by adjusting the shape of the cornea or replacing the lens.

Another way to treat myopia is to use a corneal plastic lens. This special contact lens can change the shape of the cornea when sleeping, and can correct myopia without wearing glasses or contact lenses in the daytime.
