Smart styling, lightweight, comfortable with no sharp “ouch-ies" on the nose piece. Lenses seem accurate with little or no distortion. I can read the fine print on OTC medications with these. That’s handy since the evening news routinely gives me migraines. I also like the cloth cases... a nice extra touch!After having these for a while, I can attest they are durable!. A single "night-time" pair by my bed has passed the "fall asleep reading" test hundreds of times. That's impressive considering the sheer mass of my noggin and getting buried under the forty-four pillows my wife needs.I'm not complaining about my dear beloved, …the delicate flower. Those pillows protect me from her extraordinarily violent hypnogogic jerks. I'm pretty sure she has recurring dreams of fighting dragons with Brazilian kick-boxing. Those pillows have prevented a broken nose more than once and on numerous occasions have saved the family jewels. Most other glasses I’ve tried are OK for reading, but few have survived such a hostile environment as “battlefield bed.”The other "spare pair" has survived months in the abyss of my car's center console; A dark place where masses of coins and odd machine bolts rattle as I dodge potholes. Our local street department leaves gaping caverns on all thoroughfares to prevent us falling asleep. It’s part of their campaign to improve driver awareness by making every street an obstacle course.I am one of those archaic people who still uses maps. I have to because the GPS guidance in my Honda is so screwy! It doesn’t recognize roads that have existed for half-a-century in my home town. On a trip to Baltimore, it tried to take us toward Pensacola. Without a map and these reliable glasses, we might now be on the oily bottom of the Gulf.Another pair stays by the piano for reading music. Sadly gone are the days when I could sightread fly-droppings from across the room! When our niece visits to torture me with her amazing lack of rhythm, she also shows a penchant for sitting on my glasses, or throwing them IN the piano! (She likes the sound they make… no, I’m not kidding.)Other time she seems to enjoy dropping them beneath the piano bench where merry maids quality test them with their industrial-strength vacuum. Despite bouncing around on piano strings, compression of a squirming pre-teen buttock and being swallowed whole by the world’s noisiest vacuum, they haven’t broken!So... yeah, these have held up very well where scores of other glasses have met untimely demise. One pair got scratched by flying hot metal from an angle grinder. Other than that, the remaining pairs are still like new!I got fast service from this seller too. A-OK!
