Description
The STEPPER Eyeglasses FU 1049 F620 are a lightweight, comfort-focused optical frame that follows Stepper’s German design philosophy of ultra-light construction, ergonomic fit, and pressure-free daily wear.
However, it’s important to note: FU 1049 is less widely documented than Stepper’s SI or STS series, so exact factory specs vary slightly depending on region and production batch.
