Learn How Interchangeable Glasses and Toppers Work
Interchangeable eyewear lets you change the look or function of your glasses without replacing the entire pair. A typical system combines a base frame that holds prescription or non-prescription lenses with removable glasses toppers, also called top frames.
By changing the topper, you can switch colors, patterns, styles, or add sun protection while keeping the same optical base frame.
Base Frames, Glasses Toppers and Sun Toppers
The base frame is the main optical frame and holds the lenses. The topper is the removable outer frame that changes the appearance of the eyewear. Some systems also offer sun toppers with tinted or polarized lenses, allowing compatible prescription glasses to function as sunglasses.
Snap-Fit vs Magnetic Glasses Toppers
Interchangeable glasses can use different attachment systems. Some brands use magnetic top frames, while XCombo uses a snap-fit interchangeable frame system based on mechanical engagement between the topper and compatible base frame.
XCombo’s snap-fit design is intended to provide secure retention, reduced unwanted movement, and a more integrated appearance between the topper and base frame.
