Astigmatism
What is it ??
Treatment
Whiles it’s not know what initially causes astigmatism genetics plays a factor and well as it being a result of an eye injury. The most common treatment for this condition are both corrective eye glasses and contact lenses and in very severe cases refractive surgery is done to reshape the cornea and permanently corrects vision.
Normal Vision
How does it affect vision??
Astigmatism changes the way light passes to a person’s retina which can cause distorted or blurry vision. This is also associated with hyperopia (farsightedness) or myopia (nearsightedness) most cases are severe and corrective treatment is needed, having an astigmatism makes it difficult to drive, read or see things without some type of correction.
History
Gestalt uses the approach of grouping making elements to become apart of one object which translates to configuration and organizing principles which determines how elements are grouped together and mostly things that are similar appear to be grouped together.
