Visual acuity (VA) is a measure of the ability of the eye to distinguish shapes and the details of objects at a given distance.
The right kind of lighting can make a big difference in your vision: it can improve your reading ability, create a more noticeable difference in colors, and prevent eye strain.
The most recommended indoor lighting is natural or full spectrum lighting. Full spectrum lights work by simulating natural sunlight and providing the perfect balance of brightness and contrast.
The effects can help to enhance readability, reduce glare and improve a person’s overall vision. This is especially important for professionals who work in a visual profession such as graphic arts, printing or design.
The health benefits that full spectrum light provides has been known for decades to researchers and lighting designers. There is a mountain of evidence that natural light can increase productivity, sharpen visual acuity, raise mental alertness, lower depression, balance the circadian rhythm and lower the risk of certain cancers.
