Light sensitivity


Photophobia, or light sensitivity, is characterised by a feeling of discomfort in the eye usually caused by light.

Sources such as sunlight, fluorescent light and incandescent light can all cause discomfort, thus prompting us to squint or close our eyes. Headaches may also signal light sensitivity.

Light-sensitive people may feel discomfort with very bright light. In some extreme cases, even a small amount of light can be irritating.

If you’re naturally sensitive to light, avoid bright sunlight and other harsh lighting sources.

Wear wide-brimmed hats and sunglasses with ultraviolet protection when outdoors in daylight.

Also, consider wearing glasses with photochromic lenses. Automatically adapting to changing light, Transitions® lenses darken when  exposed to outdoor UVs and return to their clear, transparent state when indoors. Uniquely designed to protect your eyes by blocking 100% UV rays and filter blue light¹ indoors and outdoors.

In bright sunlight, wear polarized sunglasses. These lenses provide extra protection against glare-causing reflections of light from water, sand, snow, roads and other reflective surfaces. As a result, your environment appears very sharp with crisp, well-contrasted colours.

¹ Blue-violet light is between 400 nm and 455 nm as stated by ISO TR 20772:2018.
² According to ISO 12312-1, the standard for Polarized lenses is to have a Polarization efficiency >78% for lens category 2, 3 & 4.
