Question: does this one have glass lens
Answer: The 1X to 2.5X magnifying lenses are ideal for reading and hands free applications like sewing and knitting, while the 3.5X lens is perfect for soldering, model building, coins, stamps, jewelry appraisal, watch and electronic repair.

Question: what is the focal length

Question: Is this product good for embroidering
Answer: Sundown products are manufactured in the United States.
Question: Will it work with my glasses

Once I thought I'd tried it would help and get tired quicker, but the effort required is not.

Answer: No, not 100% synthetic (but I had to search for that info). I went to the Glenor Company website where they describe the covering as "split leather" covered with polyurethane, or PU Leather.

Hope this helps. Thanks for asking, btw. I learned something, too.

User questions & answers

Question: The nuts that hold the magnifier to the lens came off (bad design) and were lost. We looked for hours. Can you supply replacements
Answer: It does not say cod specifically, but does say it is processed in a facility with products that may contain, among other things, fish & shellfish.
Question: Can the loupe be easily adapted to work with the LED lights
Answer: Hello! While OLLY does support the non-GMO movement in some of our products, our gummy line is presently not non-GMO verified. Sourcing exclusively non-GMO ingredients is challenging in world of dietary supplements. However, we are exploring having a non-GMO offering in the future that will give users who value non-GMO products a choice within the OLLY vitamin lineup.
Question: Is the OptiLoupe made of glass or plastic
Answer: Hello!Each gummy contains 1.5mg of melatonin, and the recommended serving is 2 gummies for 3mg of melatonin.
Question: The loupe advertises as 2.5x, 8" focal. Does that mean it has to be used with that visor lens only. Or, can I buy any diopter rating and use it
Answer: When I first started taking them, it took me about 30 to 40 minutes to get sleepy. Now that I have been taking them for almost more than 3 months, I've noticed it takes about a good 40 to an hour, depending on how tiring my day was. A tip I would give is taking it a bit in advance if you know you want to sleep early that night.

User questions & answers

Question: Are the lenses optical glass? or plastic
Answer: I work in a doctors office and we use legit blue light therapy on people. We have special protective glasses for the procedures but I wanted to see if this would help my eyes from the strong light while I checked on my patient for a few minutes and it did. Normally I’d have eye strain after looking at the light for a few seconds and with these I did not. So I’m sure they’re more than acceptable for computer and tv use!
Question: Can I wear the OptiVisor over my glasses
Answer: Gaia's capsules are called phyto-caps, which means that they are made from plants, without any animal derived ingredients.
Question: is this item U.S. made
Answer: A "manufacturer" answering this question claims that each capsule contains 760 mg of dried ashwagandha whereas the product label state 940 mg of "Proprietary Extract Blend". This "blend" is listed on the label panel as containing ashwagandha roots among three or four other ingredients. The truth in labeling will never be known, welcome to the uncharted, unregulated industry.
Question: What lens plate numbers are provided
Answer: Sleep Thru is manufactured in our facility in Brevard, North Carolina, USA.
Question: does this come withh more than one lens
Answer: No they are not, a little bigger than Tylenol pill. But we all have a different view point on large and small. They do help you sleep
