Question 1

I have eyes set close together. Do these adjust closer together ?  Or will the nose piece be in my eye site?

Accepted Answer

I have a Pupillary Distance (PD) of 62. I'm a short (5' 5"), 28 year old male who has to buy glasses from the kids section. That being said, these clip ones fit my glasses well. The glasses that I wear daily have a lens width of 47mm and a height of 24mm. The lenses on these clip ons have a width of 49mm and a height of 32mm. The lenses are well sized for my glasses. I like that they are slightly larger than my regular glasses because they cover more area. However, my only complaint is that the bridge width is 20mm. My regular glasses have a bridge width of 16mm. This means that there is a small portion of my glasses that aren't covered by the lenses of these clip ons. If your PD is close to mine, you should be fine. If you don't know your PD you can measure it yourself using a ruler with millimeter marks or a set of calipers. Just measure the distance between your pupils (the black center of your eyes). I hope this helps!

Question 2

Can I use these didymium clip-ons and the #3 clip-ons simultaneously on prescription glasses for boro work?

Accepted Answer

I'm not sure about the #3 clip-ons, but I use these didymium clip-ons with my prescription glasses for boro. Only issue is if using high heat on colors that burn bright, not quite dark enough. Works great for most day-to-day torch work.

Question 3

Has anyone had issues with these scratching their rx lenses?

Accepted Answer

I've never had an issue and I was wearing them several hours a day - I did use them on my previous pair of glasses since they fit better, so they may have been already scratched a wee bit.

Question 4

How thick are the lenses, and how do they compare to didymium  shade #5

Accepted Answer

Hi, these are about 1/8 inch thick. There is no didymium shade #5. You must be thinking of green shade, or ACE #5. Those are a green welding shade used for boro glass working in addition to the didymium. We carry a shade #3 that you can add to didymium. These didymium are good for soft glass work by themselves. If you intend on doing boro work, you need a didymium with an extra green shade #3 or #5 combination, or a set that has both in one lens.
