Definitely, if you develop a sudden change in your vision, sometimes double vision or blurred vision (Mayoclinic.org 2013). There are different cataract locations so they have names based on their location. According to “Cataracts” Linton 2012, a central cataract is located in the center of the lens (nuclear cataract) and in this case patients may still be able to use peripheral vision as they always have, they just tend to start losing vision directly in the center of the eye. The second type of cataract, according to “Cataracts: Linton 2012,” is peripheral cataract (cortical cataract) in which an individual can see straight ahead but cannot see outside of any of their peripheries. There are cataracts that affect the back of the lens (posterior subcapsular cataract) in which the opaque spot on the lens forms directly over the small area where the light path shines onto the retina. This type of cataract interferes with reading vision, distracts us and hurts our eyes when we are exposed to sunlight, and happens to cause the "halos" that some people say they see (Mayoclinic.org 2013; "Cataracts" Linton
