Product Details
The Polarized Sunglasses Test Card is a simple optical verification tool designed to help you confirm polarization in sunglasses. It’s practical for eyewear retailers, opticians, and anyone who wants to verify true polarization quickly.
- Fast polarization check: hold the card behind your sunglasses; if the lens is polarized you’ll see a distinct pattern, and non-polarized lenses won’t reveal it.
- Bulk pack of 100 pieces: ideal for inventory, demonstrations, customer gifting, or clinic use without reordering constantly.
- Compact, paper-based design: each card measures 6 x 4 cm (2.36 x 1.57 inches) for easy storage in a toolkit or display tray.
- Batch variation is normal: patterns may differ slightly between batches, but the polarization test remains reliable.
- No batteries or electronics required: a simple, low-cost solution that works anywhere you test sunglasses.
