Polarization Test Cards for Sunglasses & Lenses

Hard-paper visual test cards designed for a simple demonstration or preliminary check with compatible polarized eyewear.

How It Works

• View the card through compatible polarized sunglasses or lenses.
• The hidden image or contrast effect can become more visible through polarization.
• Compact format for optical shops, product demonstrations or personal reference.

Important: This is a visual demonstration accessory and is not a laboratory instrument or certification method for lens performance. Package quantity should be confirmed from the selected variant and product images before ordering.
