Look Sharp While Seeing Sharp

About this technology

Overview

The original SunTiger sunlight-filtering lens-derived from research conducted in the 1980s on the harmful properties of light in space and artificial radiation produced during laser and welding work-has successfully withstood the test of time. It is alive and well today in the form of eyewear that caters to the needs of any lifestyle. Over the past few years, SunTiger, now doing business as Eagle Eyes Optics, has extended its product line to over 40 styles of sunglasses. As the brand expanded, so did the product categories. Eagles Eyes has spent the last couple of years reviewing advancements in optical research. The results of this research can now be enjoyed by consumers seeking to improve their vision in environments with poor lighting. The latest product is called StimuLights. Designed specifically for low-light environments, StimuLights can be worn outdoors while driving in hazy, foggy, dusk and dawn conditions and indoors while working on computers under fluorescent lights or watching television or reading in dimly lit areas. Special cut-on and cut-off filters in the lenses relax the eyes and provide improved clarity, definition, and color contrast under these conditions. The filters cut on to let the eyes receive useful, vision-enhancing red, yellow, and green light rays and cut off to prevent blue and violet light from entering and focusing on the retina. The ultraviolet light is blocked by the lenses, therefore protecting the purple pigment in the eye, called rhodopsin, that promotes vision in low-light conditions. Industry-specific lenses are also available. For example, Eagle Eyes manufactures a lens that provides dentists protection against the ultraviolet light they are exposed to when operating curing systems for dental materials.
