Better Eyesight with Red-light, Once a Week

Read Time:30 Second

In summary, researchers found there was, on average, a 17% improvement in participants’ colour contrast vision when exposed to three minutes of 670 nanometre (long wavelength) deep red light in the morning and the effects of this single exposure lasted for at least a week. However, when the same test was conducted in the afternoon, no improvement was seen. Harpreet Shinhmar, Chris Hogg, Magella Neveu, Glen Jeffery.
