Using these Peepers blue light reading glasses is easy. Just put them on when you're using digital devices or in front of a screen to reduce the blue light exposure. You can also wear them when you're reading under bright lights for better visual comfort.
As for maintenance, use the complimentary case to store your glasses when you're not wearing them. This will protect them from scratches and damage. To clean the lenses, use a soft, microfiber cloth. Gently wipe the lenses in a circular motion to remove dirt and fingerprints. Avoid using harsh chemicals or abrasive materials as they can damage the lens coatings.
Remember, these glasses are for general use, but if you have specific vision problems, it's a good idea to consult an eye doctor. Also, keep them away from extreme heat as the frame material, although heat - resistant, can still be affected by very high temperatures.
