Using your Peepers Chester Blue Light Readers is easy. Just put them on like you would with any regular glasses. These readers are great for reducing the strain on your eyes when you're looking at screens for long periods. When you're not using them, keep them in the complimentary case to protect them from scratches and damage. To clean the lenses, use a soft, lint - free cloth. You can gently wipe the lenses in a circular motion. Avoid using rough materials or harsh chemicals as they might damage the coatings on the lenses. Also, be careful when bending the frames. The spring hinges are durable, but excessive force can still cause problems. And remember, these readers have been rigorously tested, so you can trust their performance.
