How to use

Place the glasses comfortably on the bridge of the nose and adjust the temple arms so the lenses sit directly in front of the eyes when performing near-vision tasks.

Remove them for distance viewing and clean the lenses regularly with a microfiber cloth and approved lens cleaner to maintain clear optics and prolong product life.

Usage recommendations

If you experience eye strain, blurred vision at various distances, or other visual changes, consult an eye care professional to confirm the appropriate diopter strength and to check overall eye health.
