It is well known that people with nearsightedness, farsightedness, and astigmatism do not see images as clearly as people with normal vision. But what do they see in their world? Today, Better Vision has some examples to show you.
Nearsightedness occurs when the cornea is more curved than normal, or the eyeball is longer than normal. When light reflects into the eye, it refracts more. The focal point of light then falls in front of the retina, making it difficult to see distant objects. For example, you can see books clearly, but you cannot read signs on the street far away.
Astigmatism occurs when the cornea has an abnormal shape or curvature, such as an oval or elliptical shape. This causes the focal point of light refracted into the eye to have more than one point and not fall on the retina. This results in seeing double images, blurred images, and unclear vision regardless of near or far objects. For example, you see blurry images when driving at night, or blurred or double images when looking at distant objects.
Farsightedness occurs when the focal point of light falls behind the retina. This is caused by the cornea being too flat or the eyeball being too short. The refraction of light entering the eye is therefore less, making it difficult to see near objects. For example, you cannot see books clearly up close and have to stretch your arm out to see them clearly, but you can see the road ahead clearly when driving.
If you start to see images like the examples mentioned, be sure to come and have your vision checked at Better Vision. BVAX Master will provide you with advice and find the right lenses for you so that your world can be clear again.
