The term "swimming eyes" refers to the sensation of blurred or distorted vision. There are several synonyms to describe this condition, depending on the cause. If it is due to excessive exposure to light, "photophobia" may be used. When the eyes are inflamed, "iritis" may be the appropriate term. Other synonyms include "diplopia", which is a double vision, "amaurosis", which is temporary or permanent blindness, and "scotoma" which is a blind spot. These terms may vary depending on the severity and cause of the condition, and can be diagnosed and treated by an eye specialist.
