User questions & answers

Question:	Are the clip on parts covered with rubber so they wont scratch your glasses
Answer:	Yes,they are rubber, bu there are better options out there. I tried these but they were too much trouble getting them to fit properly on the glasses & then stay positioned correctly. Try Carson's website for more options. I am a fine scale boat craftsman & Thinoptics cheeters work best for me.
Question:	Which one is best for reading small print
Answer:	the +3.00 or +4.00 should work well. I have the +4.00 and have no issue reading fine print
Question:	If i walk in walmart and near the pharmacy there are reading glasses and i use the ones that say "1.50" is it the 1.5x power/2.25 diopters? confusing
Answer:	Reading glasses are typically listed in "diopter power" which refers to the curvature of the lens. "Magnifying power is NOT the same thing, rather referring to the image size divided by the object size. There is, however a simple mathematical relationship between diopter power and magnifying power: DIOPTERs Magnifying power Working distance Where f.l. is focal length; M is magnifying power; and D is diopter power D = 40”/ f.l. M = (D / 4) +1 f.l. = 40”/D 1 1.25x 40” 1.25 1.31x 32” 1.5 1.38x 27” 1.75 1.44x 23” 2 1.50x 20” 2.5 1.63x 16” 3 1.75x 13" 3.5 1.88x 12" 4 2.00x 10” 4.5 2.13x 9” 5 2.25x 8" 7 2.75x 5.5" 7.5 2.85x 5" 9 3.25x 4.5" 10 3.50x 4" 11 3.75x 3.8" 13 4.25x 3" 18 5.50x 2.3" 20 6.00x 2” 40 10.00x 1" I didn't show the entire table, just enough to make some easy comparisons for you. Most "reading glasses" range from about 1.25 D to 3 or 4 D for close work. Common hand lenses range from about 2x - 5x, while a typical jeweler's loupe is about 10x or 40 D. For comparison, the cornea of your eye is about 43 D, while the lens behind it ranges from 17 D to 19 D, and is flexible, providing your a range of vision. I hope this helps.
Question:	I have trifocals but need magnification for crafts. Would these work with trifocals
Answer:	They work well with my bifocals; so I don't see why not. I use them for sewing, for crafts, at the piano and at the computer (the latter two things, with bifocals, keep me from having to tip my head up and getting a sore neck while I'm working). All I can say is give them a try. Clip-on magnifiers release me from holding on to a magnifying glass. I don't know if they are equal to or better than a free-standing magnifier that lots of craft and sewing people use. But they're very handy and don't require the space that that sort of thing needs.

User questions & answers

Question:	I'm having trouble attaching the lenses. I can't do it. I pulled the small lense off now I can't get the large lense on
Answer:	I believe this is the better buy. A box of 300 wipes will last me around 6 months but twords the end the packets start drying out. These sprays are great for everything where as the wipes are only good for eye glass lenses and camera lenses. I use the spray for my computer and TV as well as my glasses. The wipes are more convenient for on the go. But the sprays will definitely last longer.
Question:	Would it work for doing hand embroidery
Answer:	made in the USA
Question:	I wonder if these would help me see my computer screen better, about 1 foot away. Is this possible
Answer:	It does say safe for all lenses.

User questions & answers

Question:	Could anyone confirm whether this magnifier is suitable for vegans - if it contains any leather, wool or other animal products? Thanks

User questions & answers

Question:	What size head, in inches, will this fit? Thx
Answer:	I just received mine, in my opinion, it is not suitable for counted cross stitch. If you hold your work at the usual distance, it is too blurry. You have to hold your work about 11/2" to 2 " from your nose. I am past 60 and use reading glasses. I do think even with average eye site you'd have to hold the work that close of a distance. It would be great for getting a close up look at jewelry, model kits etc. I guess I'll have to spring for one of those lighted magnifiers on an arm.
Question:	Can I use it to play "hidden Object" games on the computer
Answer:	Yes, this can be done just by removing the screw on the left side and replace in the right one, then just position the loupe on the left side, I did the same thing since my best eye is the left.
Question:	Will these work over eyeglasses
Answer:	I tried it once. By the time I had twisted around in all directions (I'm 73) trying to see and hold my feet close enough and keeping them still, I had wiggled around until I fell off the couch and landed on the floor. Hilarious seeing this old lady trying to get up like a turtle on it's back! The only pedicuring I got was an unintended snip on my little toe. Not my toenail, but the flesh. Will not try that again. But it works really well for crocheting, tatting, knitting, reading when my eyes are hurting, plus many, many more things. I repaired an earring the other day with them. I agree with what DSE said. You need to be a contortionist!
Question:	What is the magnification if you don't use the loup
Answer:	Yes, you can wear them over your glasses. I have bifocals, it made the image blurry and I had to remove my glasses.

User questions & answers

Question:	Under the "from the manufacturer" section, it compares the 5 models. why does the 10x50 have a smaller fov than the 10x42? isn't the contrary true
Answer:	Hi Angela. This item does not come in a case or pouch. It does come wrapped but it is pretty durable and can easily be washed out by hand.
Question:	do you recommend and Carson 3D Ed 10-42 over
Answer:	Definitely hand wash. Do not use any detergent or cleanser of any kind. At first just shake out any dust, continue to use until noticeably soiled. Then soak In warm water, scrub thoroughly and hang to dry. If you need to use more quickly, use a blow dryer on low until dry or just barely damp. The cloth will last a very long time. 

Answer:	Yes

User questions & answers

Question:	how long are they
Answer:	Like a microscope the closer you look the smaller the overall picture, you back off the view "field" it allows larger area. diameter of lens v/s power. AR
Question:	Will these work on very thin wire frames
Answer:	I just got a pair of 10-42s ED and found them to be light enough in late dusk to make out things in the shadows. They seem bright enough for me. Glad I have the FOV over the 10-50s.
Question:	Can nsomeone tell me EXACTLY how long these things are
Answer:	In my view they will. I used them on safari to tracks leopards and lions viewing them from 700 metres away, enabling me to find a way to get within 5 metres of the animals to photograph them. I used s LUMIX 1000 bridge camera for that. They are the best value for money binoculars I have owned.
Question:	Will this fit on the costa del mar fantail
Answer:	Yes. The Carsons are an exceptional value and would rank up with the Vortex Vipers. I have a silly number of pairs of binoculars, Zeiss 8x40 Conquest, Nikon Monarch 5, the older Vanguard Endeavors, Kowa SV, and access to my dad's 20 year old Swarovskis. The Carsons fall right with the Swarovskis, and ahead of all th e others overall. The focus knob on the Carsons is exceptionally smooth and the sharpness is way above all but the Swarovski and the Zeiss binocs. The edge sharpness is superior on the Swarovskis, but similar to the Zeiss and way ahead of all others. Build quality is very good, though this is also true of all but the Vanguards. They are quite a bit lighter than most others, and with a no fault repair policy I expect these to be my go to binoculars for a very long time. When I have the Zeiss, swarovski and Carson binocs in front of me, I always reach for the Carsons. This surprised me, but I like them that much.
