Large, reasonable priced,

Lens size is large, 4 ¼ x 2 ½ Weight is 4 ¾ oz, 1 ½ lighter than a smaller one I have the is probably glass.No little bump with higher magnification which I find annoying when trying to read. Good for Right or Left Handed use. Weight is 4 ¾ oz, 1 ½ oz lighter than another I use with lens that is probably glass. Problem is that the surface is not precision shaped, so test appears wavey. Not a big problem , but gets distracting with expended use.
