Univo U5 C1 eyeglasses
Q (Ben Whishaw) wears a pair of Univo U5 C1 eyeglasses in SkyFall (2012) and SPECTRE (2015).
The glasses have a black / clear (transparent) gradient frame and two dots next to the lenses. The product code is 5 or U5, and the colour code is C1.
One of the glasses used in the films is currently on display at the Bond In Motion 'Cars of SPECTRE' exhibition in London (see image on the left), which confirmed the exact prodict and color code of the glasses.
The glasses are quite affordable, available online for approximately £30 (excl. prescription lenses). Get them with prescription lenses or clear lenses (if you want to wear them just as a fashion statement) at SelectSpecs.com (I bought my pair here and I received the same model as Q's glasses), MaxEyewear, Eyekit.co or BuyNewsSpecs.ie.
