Frequently asked questions
Are the William Eyeglasses suitable for all face shapes?
Yes. William design was created with balanced proportions that complement most face shapes. Its bold round silhouette and refined bridge create harmony on oval, square, and heart-shaped faces, adding definition without overpowering natural features. With a 44–26–145 mm fit, the acetate frame adapts comfortably to different face widths, ensuring both aesthetic balance and a secure, effortless fit.
What level of protection do the lens categories offer?
William are equipped with high-quality lenses offering UV400 protection, blocking 100% of UVA and UVB rays. Depending on the color variant, lenses range between Category 2 and Category 3, providing strong defense against sunlight and glare.
- Category 2 lenses filter medium-intensity light, ideal for bright but not extreme conditions, softening glare while keeping vision natural.
- Category 3 lenses deliver high protection, perfect for intense sun exposure such as beach days, driving, or outdoor travel.
- William Blue Light models, on the other hand with Blue Light Blocking technology, reducing eye strain from screens and providing UV400 protection for daily indoor use.
Are the William comfortable for long wear?
Yes. Every William frame is crafted from premium acetate, known for being lightweight, durable and naturally adaptive to the face’s contours. The 44–26–145 mm dimensions ensure ergonomic balance and an even weight distribution, preventing pressure points on the nose or temples. Whether used for work, travel or leisure, they maintain comfort and structure, making them ideal for prolonged use throughout the day.
