What is glare? You can experience glare in different circumstances. If you look directly at the sun, you will have to immediately close your eyes or look away due to the bright rays. This is disability glare. When the light shines directly into your eyes, you are no longer able to see clearly.

It is mostly caused by annoying reflections on computer screens and furniture or by lack of contrasts.
