A new and improved snap-on sunglasses includes a first sunglass lens support assembly which supports a first lens frame portion. A first sunglass lens is supported by the first lens frame portion, and a first clamping arm assembly is supported by the first lens frame portion. A second sunglass lens support assembly supports a second lens frame portion. A second sunglass lens is supported by the second lens frame portion, and a second clamping arm assembly is supported by the second lens frame portion. The respective first and second clamping arm assemblies include respective clamping ends. A first variable length alignment assembly is connected between the first sunglass lens and the second sunglass lens, for maintaining the lenses in substantial co-linear alignment. A second variable length alignment assembly is connected between the first lens frame portion and the second lens frame portion, for maintaining the frame portions in substantial co-linear alignment. A tension-exerting assembly, which includes a spring, is connected between the first sunglass lens support assembly and the second sunglass lens support assembly. The tension-exerting assembly urges the first sunglass lens support assembly and the second sunglass lens support assembly toward each other, such that the first clamping arm assembly and the second clamping arm assembly clamp against the frame of the eyeglasses. A plurality of suction cups may be connected to the respective clamping arm assemblies. The effective lengths of the respective clamping arm assemblies are adjustable.
