text: This shouldn't be considered a hard negative, but it is a caution.  If your glasses are on the larger size; aviator style lenses, etc, these likely won't fit fully over them and coverage may be less than complete.  I wear lenses that are 55x44 mm.  These over glasses have lens &#34;cavities&#34; that are about 65x42 at the &#34;bottom.&#34;  My glasses don't fully fit inside and the coverage is &#34;clunky&#34; at best.  If you're glasses are smaller (and most are, I think) you may be OK.  These are also made from very cheap and brittle plastic.  I see the ear pieces especially breaking with just a little rough handling.  They are clearly only a $10 product.  They are effective as driving glasses, cutting UV and especially blue light.  Know what you're buying and don't expect to have to mention them in your will.
