The eyes’ irritation in response to the light is termed as photophobia. It is a common complaint in many people. It may occur without a significant reason in many cases. However, it is linked to some underlying disease in other instances.
Photophobia is like an allergic reaction and patient experiences blurring of vision and sore eyes soon after he is exposed to the light. The level of sensitivity varies among different people. Some people require very intense light to elicit photophobia and others get symptoms in a low light too.
Major causes for inducing discomfort in response to light are:
Ulceration of cornea
Wearing contaminated lenses
Eye diseases such as glaucoma
Certain drugs, like atropine etc.
Symptoms vary depending upon the severity of the condition. It may range from mild to severe pain on exposure to light. Blurred vision, headache and fever may accompany.
Diagnosis of photophobia is based on complete history and physical examination of eyes. Slit-lamp examination, pupil dilation, corneal scraping and lumbar puncture may be required in severe condition.
The treatment involves protection of eyes from the bright light. Avoiding the bright light, wearing dark sunglasses, and darkening the room relieve the symptoms. Other treatment options focus on curing the underlying cause.
