FAQs
Are these glasses polarized?
The Bloc Jack Sunglasses feature XTR Karbon8 optical class one lenses, which are high-clarity and impact-resistant, but they do not specifically list polarization as a feature.
What does Category 3 lens mean?
Category 3 lenses are designed for strong sunlight, offering high levels of glare reduction and UV protection, making them ideal for everyday use in bright conditions.
Are these suitable for all face shapes?
The Jack series is designed as a unisex frame, making it versatile for a wide range of face shapes and sizes.
Can I replace the lenses?
These lenses are fixed to the frame for stability and impact resistance. Lens replacement is not recommended by the manufacturer.
Are they safe for driving?
Yes, they are suitable for daytime driving. However, because they are Category 3 (dark), they should not be worn for night driving or in very low light.
Troubleshooting
Smudges or blurry vision
Clean the lenses using a clean microfiber cloth; avoid using clothing or tissues which may contain fibers that scratch the lens.
Glasses sliding off the nose
Check if the frame arms have loosened; a professional optician can adjust the tension of the hinges if necessary.

Setup, Compatibility & Care
No assembly is required for the Bloc Jack Sunglasses. To ensure longevity, always store the glasses in a protective hard or soft case when not in use to prevent scratching the Karbon8 lenses. When cleaning, use only a microfiber cloth and, if necessary, a gentle, pH-neutral lens cleaning solution. Avoid using abrasive paper towels or household glass cleaners, as these can strip the UV protection coatings over time. Ensure the frames are kept away from extreme heat sources, such as car dashboards in direct sun, to prevent potential warping of the recycled plastic material.
