The McAllister MC4506 Eyeglasses deliver classic square styling and all-day comfort at a price that makes prescription eyewear accessible. Built from durable acetate with a distinctive matte finish, these unisex frames combine a refined silhouette with practical features that work for everyday wear.
The square shape offers versatile appeal—it adds definition to round or oval faces while maintaining a professional look that transitions from office to weekend. The full-rim construction provides maximum lens stability and supports a wide range of prescription strengths, including single vision, bifocals, and progressives. At 55mm lens width with a 17mm bridge, the MC4506 fits most adult faces comfortably.
Spring hinges are built into the temples, allowing the arms to flex outward beyond 90 degrees for a flexible, pressure-free fit. The thin temples keep the overall profile sleek without adding bulk behind the ears.
Available in three versatile finishes—classic Black, warm Tortoise, and modern Grey Gradient—the MC4506 adapts to different personal styles. The acetate construction offers hypoallergenic properties and resistance to everyday wear, while the matte finish minimizes fingerprints and maintains a clean appearance.
The MC4506 represents straightforward design, solid construction, and prescription-ready versatility for anyone seeking dependable eyeglasses without the premium markup.

Frequently Asked Questions
Are the McAllister MC4506 eyeglasses prescription-ready?
Yes, the MC4506 frames are fully prescription-ready and compatible with single vision, bifocal, and progressive lenses. The full-rim acetate construction provides the stability needed for a wide range of prescription strengths, and the 55mm lens height offers sufficient vertical space for progressive lens zones.
What are the frame measurements for the McAllister MC4506?
The MC4506 measures 55-17-140, meaning a 55mm lens width, 17mm bridge width, and 140mm temple length. This is considered a medium to large fit suitable for most adult faces. The square shape and full-rim design work well for those needing frames that can accommodate thicker prescription lenses.
Do these eyeglasses have spring hinges?
Yes, the McAllister MC4506 features spring hinges that allow the temples to flex outward beyond 90 degrees. This provides a more comfortable, flexible fit that adapts to your head shape and reduces pressure on the temples during all-day wear.
What face shapes work best with square eyeglass frames?
Square frames like the MC4506 work particularly well for round and oval face shapes, as the angular lines add definition and structure. They help balance softer facial features by creating contrast. People with round faces should look for square or rectangular frames to add sharpness, while those with oval faces can wear square frames to add width.
What is acetate and why is it used for eyeglass frames?
Acetate is a plant-based material known for its durability, hypoallergenic properties, and smooth surface comfort. It's lightweight compared to similar materials, offers excellent color depth and luster, and is suitable for nearly all prescription strengths. Acetate frames are also more environmentally friendly than petroleum-based plastics.
What colors are available for the McAllister MC4506?
The MC4506 is available in three color options: 001 Black (classic matte black), 240 Tortoise (warm brown tortoiseshell pattern), and 020 Grey Gradient (modern grey finish). All three feature the same matte finish that reduces glare and fingerprints while maintaining a refined appearance.
