The UV filter is found in the material of the eyeglass lens and is completely independent of the degree of tinting.
Sunglasses that only attenuate visible light and do not absorb the UV filter damage the eye because they disable the eye's natural protective mechanism in the form of a narrow pupil, which in this case is wide.
Without dark glasses, the eye itself would react to light conditions by narrowing the pupil and closing the eyelids.
