I can understand the issues. I have had a few kickstarter projects that did not deliver.
And I wondered about the horizontal orientation of the soldering iron. According to the comments, it is due to needing to put the camera and LED light on the iron.
As I approach my 68th trip around the sun, being able to see the components when soldering is becoming an issue. The head mounted magnifier system I use is uncomfortable to use with my glasses.
I now have special safety glasses for soldering and wood working. These safety glasses uses Polycarbonate lenses and side shields.
I have gone back to using bi-focals for these safety glasses. I have switched to using progressive lenses for my normal reading and computer glasses (I still use tri-focals for distance glasses). I find having the explicit transition from reading glasses to intermediate in the bi-focals helps when I'm focusing on small things. It does take practice to know the angle of my head to switch distances, but I have many years of practice using bi-focals, tri-focals, and progressive lenses.
Some of the online places I have ordered glasses from do not offer safety glasses in bi-focal format. I use the Chinese company
Optical Factor which can make safety bi-focals. Now, the frames that they provide aren't as sturdy as the frames I get from (
Zenni), but for the specialized use of soldering and woodworking, they are acceptable. I wish Optical Factor also offered safety glasses in Trivex, but they don't. I also wish Zenni offered safety glasses in bi-focal format, but they don't.
FWIW, the sunglasses I wear in my profile come from Optical Factor, and I added leather side shields to block out the sun. However, I could not get Optical Factor to make the glasses combining polarization and bi-focals. They sent me a pair that was not polarized, but it was dark. I complained, and they sent me another pair that also did not have polarization. So I eventually sent the glasses to a company (
Use My Frame) that replaces lenses in existing frames and I got the polarized tri-focals that I wanted. My first pair of glasses frames eventually broke, and I needed to order a second pair. I find when I'm outdoors, I need to use polarized sunglasses to reduce my migraines.
If you are wondering, there are different materials that lenses are made out of:
- CR39 plastic: Most lenses are made with CR39 these days. It has high optical clarity at a low cost. It does not have UV protection, but that can be added as a coating. You cannot use CR39 for strong prescriptions or rimless glasses.
- Polycarbonate: These lenses have a high impact resistance and natural UV blocking. However, CR39 and Trivex glasses have better optical quality than polycarbonate lenses. Generally polycarbonate lenses are more expensive than CR39 but cheaper than Trivex.
- Trivex: Trivex glasses combine high impact resistance and good optical quality (better than either CR39 or Polycarbonate). The downside is they cost more. In my last set of glasses, I found I could not order Trivex glasses that were tri-focals and offered photochromatic transitions, and I had to go down to CR39.
- High index plastic: These are special lenses made for strong prescriptions.
- Glass: Glass offers the best optical quality and scratch resistance, but the lenses are heavier and not impact resistant. Generally glass is used for specialized high power prescriptions.
