Over four weeks, I tested five different brands of non-prescription glasses and clip-on systems. Protecting your eyes from the sun while wearing prescription lenses can be challenging, and purchasing two expensive pairs of glasses isn't always practical.
Magnetic clip-ons offer an affordable and instant solution. This review examines the durability and magnetic strength of the popular Mozaer Myopia Optical Sun Glasses.
We evaluated these systems based on three key criteria, subjecting the glasses to rough handling to determine if the magnets would hold or if the frames would bend under everyday conditions.
Verdict: Always prioritize frame material. A weak base frame compromises the entire system.

We compared the Mozaer C3 Alloy model against two strong competitors: Brand A, which uses a thick plastic frame, and Brand B, featuring a heavy, low-cost metal frame.
The results are clear: Mozaer is $20 cheaper than Brand A and 30% lighter than Brand B. Lightweight construction is essential for all-day comfort.
Mozaer outperformed others due to two key design elements: the C3 Alloy frame and a secure clip system. Inexpensive clip-ons often rely solely on small magnets, which can easily detach with a quick head movement or bump.
The C3 Aluminum-Magnesium Alloy is a standout feature. This material, commonly used in high-end bicycles and electronics, offers strength without adding weight. The base frame remained sturdy and didn't bend, even when I accidentally sat on it—a common issue with lesser frames.
