A decent-quality visor, easy to assemble, lightweight, comfortable to wear (even over glasses), can be tilted up out of the way when not in use.
A decent-quality visor (see, "Comparisons"), lightweight (you really don't notice wearing it).
It comes flat-packed but is easy to assemble.
It fits comfortably, even over spectacles. Padded over the brow. Easy to adjust to any size of head.
Can be tilted up out of the way when not in use.
Please do not confuse this with the many cheap models that were widely advertised during the pandemic - they were too small to fit most humans (they were 8 inches wide X 7½ tall - ours is a comfortable 11 inches wide X 8½ inches tall). Also, the cheap models were too thin and lightweight. You wouldn't think it important that a visor has "good optical quality" but the very cheap models were so thin it was like looking through Cellophane, everything appeared wobbly, which isn't a good idea while you are handling fine jewellery and acids!
