An eye protector comprises a spectacle frame with an eye piece 2 having an annular lip on its rear surface which engages a corrective lens 12. Eyepiece 2 may be coloured and/or infra-red and ultra violet light absorbing and may have refractive power especially in an annular region around corrective lens 12. Eyepiece 2 may be a segment of a sphere and of such a size that it closely covers the wearer's eyeball to protect it from incident light from all directions.
