Astigmatism, myopia, hyperopia, and contact lenses have special lenses.Do you know what makes it different? This section introduces the difference between astigmatism and myopia and hyperopia.

In addition, we will introduce how to choose contact lenses when you have astigmatism in only one eye. When purchasing astigmatism contact lenses

What's the difference between astigmatism contacts and myopia and hyperopia contacts?

Astigmatism, myopia, and hyperopia refer to the condition in which objects are not normally focused on the retina and appear blurred. Each can be corrected with glasses or contact lenses. Here are the differences between them.


Astigmatism is caused by corneal distortion, so the light entering the eye is not focused in one place.Astigmatism mainly uses cylindrical lenses to refract only light in a particular direction and focus on the direction of astigmatism.In addition, depending on the type of astigmatism, hard contact lenses may be used for correction.


Myopia occurs when light enters the eye and focuses in front of the retina, either because the eye is too deep or because the lens or cornea is too refractive.For myopia, use a concave lens with a thinner center than the surrounding area to correct the focus.


Farsightedness is a condition in which the retina is not focused and appears blurred when viewed far away.Contrary to myopia, convex lenses with thicker central parts than their surroundings are used to strengthen the bending of light and focus.

Contact lenses for astigmatism, myopia, and hyperopia have these differences. This is the same with the prescribed contact lenses .In order to correct your eyesight properly, be careful to choose the contact lens that suits you.


In the case of astigmatism in one eye and contact lenses in the other eye, it basically depends on the degree of astigmatism.

If the degree of astigmatism is between -0.25 and -0.75, both left and right contact lenses can be used.If you have more astigmatism than that, you should use astigmatism on one side and normal contact lenses on the other.

Also, astigmatism contact lenses are generally more expensive than regular contact lenses, so there is no problem with deciding after consulting with the budget.Light astigmatism does not affect your eyesight, so you can use normal contact lenses instead of astigmatism.
