LightSpecs Nighttime Readers Tortoise +2.5 Strength - Perfect for Reading in Bed & Low Light Conditions

I use these to read in bed while my wife sleeps.They really only light up what your looking at which is pretty cool.Also I use them to get around at night in the dark while my wife sleeps.Much more directional than a flashlight but a bit spooky to any one looking at you or to yourself in a mirror.It's not clear why there are varying prices for different reading strengths.what a godsend! now I can crochet, read, whatever - and not wake the cat!got a pair 2 mo. ago & loved them, so got another pair. they have both worked perfectly and the batteries last quite a while.I knew that if they were defective, amazon would make it right. LOVE these people!!!!Been using these specs for years I love them, great for travel ie planes at night, for reading in dark places, doing small projects, reading menus in dark restaurants, my medical friends love them too ..I have tried about a dozen different kinds of reading lights. These lighted readers are exactly what a need. The light is good. Being able to buy in various strengths is important. And I'm able to read on my side in bed, something I can't do with my regular progressive lenses.Works great, but could be a little more durable.Love them! I use them to read at night and when I use my laptop.I can have the room lights off and enjoy my book or surfing the internet.I have done everything and they don't work, the glasses will not light up, my only regret is I didn't notice in time to send them back.Great for reading, without bothering my husband at night.
