What is the name for eyes that don't focus properly?

Answer 1

Almost any vision disorder or disease of the eye can cause improper focusing. Here are just a few of the more well known ones.

Myopia (nearsightedness): The inability of the eyes to focus on distant objects. Normally treated with corrective lenses or Lasik surgery.

Hyperopia (Farsightedness): The inability to focus on near objects. Normally treated with corrective lenses or Lasik surgery.

Asthenopia: Often referred to as Computer Vision Syndrome, caused by eye strain when doing a visually intensive task over an extended period. Commonly treated with polarized, corrective lenses, and scheduled periods of rest.

Amblyopia (Lazy Eye): Poor or indistinct vision in an otherwise normal eye, can be caused by either no transmission or poor transmission of the visual image to the brain for a sustained period of dysfunction or during early childhood. Most frequently treated using patches on the good eye, and/or vision exercises.

Strabismus: A condition where the eyes are not properly aligned with one another, the result of a discoordination of the extraocular muscles controlling both eyes. This is most often treated with eyeglasses, prisms, vision exercises and in some cases, surgery.

Anyone experiencing a sudden change in vision, whether it be blurred, doubled, obstructed, fading, dark spots, sparks, or anything else, should immediately seek the assistance of an opthamologist physician. Even when the symptoms are only temporary, they can be signals of a serious condition that can lead to blindness.
