LED light therapy lamp provides a broad spectrum of light therapy which stimulates the photoreceptors in the eyes. Exposure affects people differently. It is important to establish a distance and schedule of use that is comfortable for you and your eyes. We recommend you use the light regularly and at about the same time each day. When you are feeling sluggish and lethargic, spend more time with the light therapy lamp or increase the light intensity.
