How to use

Put the glasses on so the lenses are aligned with your eyes and sit comfortably on the bridge of your nose. Use them for close work that requires magnification, such as reading small print or performing detailed tasks; remove them when looking at objects at a distance. Store the readers in a protective case when not in use to prevent scratches and keep them clean with a soft microfiber cloth and lens cleaner suitable for coated lenses.

Usage recommendations

Have a current eye examination if you experience eye strain, headaches, or difficulty focusing; over-the-counter readers are intended for simple near-vision needs and do not replace a comprehensive eye exam or customized prescription lenses.
