uveitis is one of the most common causes of light sensitivity. As a result of inflammation in the lining of the eye blood vessel, uveitis is characterized by redness, eye pain, headache and significant sensitivity of light. Uveitis may be the result of trauma, surgery or underlying systemic disease such as lupus, rheumatoid arthritis or ankylosing spondylitis.
