The cornea and lens are generally even and rounded equally in all directions. This mechanism helps the eye to focus light emissions sharply against the retina at the back of the eye. In the cornea of an average eye the lens focuses light waves on the retina. If the cornea or lens isn't smooth and equally rounded the light waves will not be refracted properly. This is stated as an inaccuracy in the refraction of light in the eye.
In an eye with astigmatism, images are fixated in the anterior of the eye, past the retina, producing equally near and far-off images to seem hazy. This is the main symptom of astigmatism. Other symptoms include; blurry or distorted vision at any distance, sensitivity to light, headaches and locational migraines, excessive squinting (the person is constantly closing his/her eyes), or any type of strain of the eye. The strain on the eye could occur when driving or reading for a prolonged period of time. All of the following are impairments of perception caused by visual impairment; Visual-Motor Integration (eye-hand, eye-foot, and eye-body coordination), Visual-Auditory Integration (the ability to relate and associate what is seen and heard), Visual Memory (the ability to remember and recall information that is seen), Visual Closure (the ability "to fill in the gaps" or complete a visual picture based on seeing only…
