Theory FL04: Clear Blue Round Eyeglasses
Theory FL04 brings a splash of color to the round frame. The acetate is a translucent clear blue that looks fresh in daylight and soft indoors, and the full rim gives each lens a neat, defined outline.
It is a unisex frame for men and women who want glasses that feel a little more personal than black or brown. The size M frame uses 50-23-145 sizing: a 50 mm lens width, 23 mm bridge and 145 mm temples, with a 144 mm overall width. Blue is the frame color only and says nothing about the lens tint or coating. Try it with white, navy or grey outfits. Add prescription, blue light or reading lenses in our lens selector when you order.
