Common Problems & Solutions
This usually happens due to glasses that are too big, frames without proper grip on the nose, or sweat and humidity loosening the fit.
- 1Try nose pads: If your frames have adjustable nose pads, bend them slightly outward for a better fit.
- 2Use silicone nose grips: Adhesive silicone pads stick to the frame and improve grip.
- 3Choose smaller or wrap-around styles: These stay put better during movement.
- Wearing oversized frames if you have a small face
- Ignoring frame material—cheap plastic bends easily and loses shape
