Lightest spectacles or glasses frame

According to Official Guinness Records,

The lightest commercially available spectacles frame weighs 1.01 grams (0.04 oz) and is produced by Spectral Optics and Mr Nestor Clemente Grimaldi (both Mexico). It was presented and weighed in Mexico City, Mexico, on 20 May 2010.
The frame consists of three separate pieces that only form a pair of spectacles together with some glasses. The weight was the pieces of the frame plus nose pads. The weight without nose pads was 0.77 grams (0.03 oz). The weight was the average of weighing three different copies of the frame which were randomly selected from 9 copies by the notary.
