A few questions

Hi, I have a few questions about your frames/lenses. Im looking at the 'Cat Eye Reading Glasses' b/c they seem to check the most boxes in terms of what I am looking for - readers w/ blue light blocking for 'screens', that transition to 'sunglass readers' that I can use at the beach, hiking (reading the map), etc. Do I have that correct? If so, can you tell me the total length of the frames? That information isnt listed in the specs. I have a somewhat narrow face and want to make sure they wont overall be 'too wide'. (For reference, I have a pair of 'Marshall Ray Bans sunglasses that fit me perfectly and they are 132 in length. To be clear Im referring to the horizontal length of the frame across the face, not the part that goes over the ear.)) I also wanted to know if the frames come standard with uva/uvb protection, anti-scratch and anti glare protection. (Ive looked on your website but cant seem to find that information.) Lastly, I do see that the frames can be returned if they don't work, but wanted to make sure that includes frames that have a 'prescription' (readers) in them. One more very last question: If the frames are too big or too heavy for me, do I understand correctly that the 'clip on readers' you sell will allow me to clip them on to my sunglasses so I can do 'outside reading'? Not my first choice because what I mostly need is readers for 'always' but at least it will be something while Im looking for actual frames. I'm already dorky looking and fortunately dont have co-workers so Im not concerned about how ridiculous I'll look. I just want to be able to use my eyes! Opps re-reading realized I forgot to ask what the weight of these frames are. Ive never been able to wear plastic frames because they are too heavy and give me that 'headband headache' over the ears. But Im having such a hard tie finding frames/lenses that suit my needs, Im hoping maybe technology has advanced over the years and plastic frames are maybe less heavy? Probably not but if I can get that spec it would help me make some decisions! Ok, thank you very much in advance! - Jenny
