Do these glasses really reduce blue light?

The lenses are described as blocking about 40% of blue light with almost no color distortion. That is partial filtering, not a full blue-light block, so expect a modest effect rather than a strong amber tint.

What are the frame and lens measurements?

The frame is about 5 3/8 inches wide. Each lens is about 1 3/4 inches wide and 1 3/4 inches tall, the bridge is about 9/16 inch, and the temples are about 5 1/2 inches long.

Are the lenses glass or plastic?

The lenses are acrylic and the frame is plastic with spring hinges. Acrylic is lighter than glass but scratches more easily, so store them in a case.

Will the lenses change how colors look?

The lenses are made to filter blue light with almost no color distortion, so whites and screens should look close to normal rather than yellow.

What comes in the pack?

The pack contains four pairs of reading glasses. A case and cleaning cloth are not listed, so plan to store them separately.

Are these good for computer work?

They can help with screen reading and add mild blue light filtering. The small lens height gives less coverage than a larger frame, so heavy all-day screen users may prefer a wider lens.
