Using your Peepers Birdie blue light readers is easy. Just put them on like you would any regular glasses. They're great for reducing eye strain when using digital devices or in front of a screen. For maintenance, clean the lenses with a soft, lint - free cloth. Avoid using abrasive materials as the dual anti - scratch coating can be damaged. When not in use, store them in the complimentary case to protect the frame and lenses. Keep them away from extreme heat as the frame, although heat - resistant, may be affected by very high temperatures. Also, remember that these glasses have been rigorously tested, so you can trust their quality.
