Light eye sensitivity, also known as photophobia, is a condition in which the eyes become extremely uncomfortable to the presence of light. MedlinePlus says light sensitivity is common and may be a sign of certain underlying medical conditions. Light sensitive eye disorders can be treated.
Migraines
A migraine is a headache that typically affects people between age 10 and 46, according to MedlinePlus. Specific migraine symptoms include light sensitivity, vomiting, nausea and head pain especially on one side of the head. Migraines can also lead to blurry vision, eye pain, tunnel vision and seeing abnormal shapes or lines within the visual field.
Alcohol, bright lights, stress, exercise, loud noises and perfumes can trigger a migraine. Foods such as chocolate, dairy products, nuts and fruits also can trigger a migraine.
Resting and applying a cool compress onto the head are simple measures that can be taken to help relieve a migraine. Sometimes, medications such as venlafaxine, topiramate, verapamil or amitriptyline can be prescribed to reduce the frequency of the migraines. Also, over-the-counter medications such as acetaminophen can be taken. Medications such as sumatripatan and ergotamine with caffeine also can be prescribed to manage migraines.
Corneal Abrasions
The American Academy of Family Physicians (AAFP) says a corneal abrasion refers to a scratch or cut of the cornea, a thin layer of tissue over the iris (the colored part of the eye). Its website FamilyDoctor.org explains that the cornea is responsible for focusing light.
Specific symptoms of a corneal abrasion include eye pain, blurry vision, a sensation that something gritty is stuck in the eye and tearing of the eyes. Corneal abrasions also can lead to a headache. Prescription eye drops or ointments will be prescribed to treat the corneal abrasions. FamilyDoctor.org says that the corneal abrasions should heal within one to three days.
Corneal Ulcer and Infections
MedlinePlus reports that an open sore can develop on the cornea. This can typically lead to an infection. Specific symptoms of a corneal ulcer and infection include eye light sensitivity, pain, redness, burning and itching or discharge. Corneal ulcers and infections also can lead to watery eyes, a white patch on the cornea and visual problems.
Bacteria, parasites, fungus or viruses can lead to corneal ulcers and infections. Other causes of this condition include corneal abrasions (scratches), dry eyes, an allergic eye condition, foreign bodies in the eye and inflammatory disorders. Treatment for corneal ulcers and infections is dependent upon the cause. Antibiotic, antiviral, antifungal or corticosteroid medications can be prescribed to manage corneal ulcers. In severe cases, a corneal transplantation may be necessary.
