I like that the sunglasses are light enough that isn't too dark after you put them on. I bought mine with a very low (1.25) magnification so that when driving I can read road signs without having to use my stronger (2.5) reading glasses which are too much to drive with. I like that they are all over magnification so I don't have to have my head tilted all the way back to be able to see things straight in front of me like you have to do when you have on bifocals. They are also stylish and don't look like &#34;old lady&#34; glasses.
