Blue light, defined as high energy visible light, is emitted from the sun and many common, contemporary electronic devices. While moderate exposure to natural blue light can impact health positively, overexposure to artificial blue light may threaten bodily health – and eye health in particular. To reduce the harmful risks of blue light, the expert eye doctors at Overland Optical Family Eye Care recommend wearing advanced computer glasses. With over 35 years of serving St. Charles and Overland with advanced eye care, this popular optometry practice now features an extensive selection of specialized, protective eyewear for computer use.
