Also known as photophobia, light sensitivity is a condition where people experience discomfort or intolerance in the presence of bright light. Although powerful lamps and bright sunshine can be particularly problematic, light sensitivity can be a symptom of an underlying problem.
Our eyes are sensitive organs, and a sense of being exposed to bright lights can trigger headaches and nausea alongside the natural reactions of squinting or shielding the eyes.
Light sensitivity can occur because of dry eyes or corneal inflammation and new medication can sometimes induce light sensitivity, as can certain conditions like cataracts or conjunctivitis.
Symptoms may be alleviated with wide-brimmed hats that block out sunlight, or wraparound sunglasses with UV protection that provide full eye cover.
Photochromic lenses adjust their tint according to ambient light conditions, and polarised lenses are excellent at blocking glare from wet or reflective surfaces. We can also explain the benefits of all types of coatings and tints.
Did you know? People with lighter coloured eyes may be more prone to light sensitivity. Darker irises contain greater levels of melanin, which protects against harsh lighting.
