How to use: Simply put on the glasses like you would any regular pair. The soft nosepiece will help keep them in place comfortably. When outdoors, these glasses will protect your eyes from the sun's glare and harmful UV rays. Note: Don't use these glasses for activities they're not designed for. Avoid scratching the lenses. Maintenance: Clean the lenses with a soft, dry cloth. You can also use a mild lens cleaner. Store them in a case when not in use to prevent damage.
