These are swimming goggles used for elementary school pool swimming classes. There are scratches on the lens. I don't think they will be noticeable underwater. The size can be adjusted for adults by changing the nose belt. The nose belt is made of soft material. These are prescription goggles with a myopia correction of -2.0 for both left and right eyes. If you wear glasses, you'll understand that even if the prescription isn't the same as your everyday glasses, slightly weaker prescription glasses can be quite usable, so a perfect match might not be necessary. - Color: Black - Design: Swimming goggles - Strap Type: Adjustable strap ■ Color: Smoke (clear lens) ■ UV cut processing ■ Anti-fog processing ■ Material: Lens Polycarbonate 　　　　　　Face pad Elastomer 　　　　　　Buckle Polycarbonate 　　　　　　Strap Silicone
