Causes of wavy vision include glaucoma or increased pressure in the eye, an eye injury, and retinal detachment, according to Healthgrades. In addition, conditions emanating from the head or other parts of the body may lead to vision distortion. Other causes of wavy vision include infection, trauma, inflammation and malignancy.
The major causes of vision distortion are refractive errors including shortsightedness and longsightedness, reports Healthgrades. These are forms of blurry vision caused by irregularly formed corneas. Similarly, head injury, stroke, temporal arteritis and certain medications may cause distorted vision. Vision problems may also be caused by presbyopia, or difficulty in focusing on objects in close range; cataracts, or cloudiness over the eye lens; and diabetic eye disease, reports MedlinePlus. Other causes include night blindness, macular degeneration and brain tumor.
There are various forms of eye problems and vision distortions, including halos; blurred vision, or the loss of sharpness of vision and failure to notice fine details; blind spots; or scotoma, which is an area of diminished vision. Other types of vision distortions include sensitivity to light, impaired depth perception, double vision and poor nighttime vision. Whereas some forms of eye distortions may not be as serious, certain problems may signal a grave condition or medical emergency, as reported by Healthgrades. Vision distortions resulting from serious life-threatening diseases and conditions, including psychosis and ingestion of toxic plants, warrant immediate medical attention.
