USFans Eyewear Spreadsheet

Compare the frame shape and its measurements

Start with a frame you find comfortable and note the available lens width, bridge and temple measurements. Check the meaning of each figure in the selected listing. An overall width is not interchangeable with the width of one lens, and the bridge deserves its own comparison.

Compare front and side views for the shape and the temple construction. A narrow-looking photo can result from the shooting angle rather than a genuinely smaller frame. Keep the selected color and size with the original link.

Separate tint and styling from UV protection

The FDA’s sunglasses guidance explains that a darker lens does not itself establish greater UV protection. It recommends checking UV labeling. Use that distinction when reading a listing, and do not treat a dark or mirrored catalog image as evidence of protective performance.

This guide has not tested the lenses or verified the labels on these products. If protection is a requirement, obtain dependable product documentation rather than relying on a logo or a seller photograph. A style comparison is not a safety test.

Confirm what lenses and accessories are included

Read whether the listing describes sunglasses, a frame with demonstration lenses, or another configuration. Do not assume that a frame is ready for prescription use or that a case and cleaning cloth shown in a styled photo are included. The exact option must establish the contents.

For an order with inspection photos, compare the selected frame color, visible hinge and temple details, and included pieces. Photos can reveal visible mismatches, but they cannot establish optical accuracy or certify UV performance.
