Auto Darkening Helmets. Is there a difference?

[MinnesotaEric]

I thought Bi-Focal Contacts were just kind of like B-Focal Glasses, only in a tiny version. You need to whip your head up and down depending on whether you wish to see far or near.

Speaking of bifocals, as a younger man, I had always wondered how woodworkers, older woodworkers with years of experience, managed to cut their hands and fingers until a friend of mine pointed out the difference where one's hands appear to be relative to where they were looking through their bi-focal lenses.

Everybody stay safe out there.

I notice my limbs coliding with more and more object. Not sure why. Not good if it's some sharp, spinning thingamijig.

That’s a good point.

No Bi-focal or sometimes called multi focal contact lenses use your standard prescription on the outer part of the contact and the reading distance prescription on the center. So when you are looking at distance your eye uses the outer part of the contact to focus, but when you move into reading distance your eye tends to focus more toward the center which is the reading part of the contact.

I have worn the bi-focal contacts for about 4 years now, but some doctors will set you up with a distance contact in one eye and reading distance in the other and then you use which ever eye for what you are doing. I can't to that because if my contacts are out of focus from each other it gives me headaches.

Thanks for clearing that up. I always wondered how they would keep the bi-focal contacts in the correct orientation.

I once tried a system where contacts worn at night reshape your eyeball so you don't need correction during the day. What a disaster!

What I had in mind about any 'bi-focal contact lens' method/system. I gotta think that this is for folks with 'mild' prescriptions. Say 3.00 or less on myopia, and 1.5-2.00 on presbyopia at most.

Looking forward to trying out new hood with new Everlast welder this weekend. If the helmet works ok, I might admit which cheapo I bought.

Either way we’ll get it out of you.

Hey. Those two AD’s I bought for five bucks each were so cheap they couldn’t afford to print labels for them.

I bought a low-end Miller helmet.
I have always thought it was strange.
Like the its blurry the first couple seconds after darkening.

Then I bought an Harbor freight helmet, so I could help folks learn how to weld.
I found ther Harbor Freight unit to be much better than the Miller.

I was reading some welding stuff tonight and stumbled upon two articles relevant to this thread. First, about 20 auto-dimming hoods grouped by price range were compared and Jackson's True Sight II, W70 lens won the upper end. https://weldingequipmentpro.com/buying-guides/best-welding-helmet/
Second, an article that explains the EN379 rating system of auto-dimming hoods is interesting and a good way to judge what to expect from a welding hood when you see it on a shelf, in a box at your local store. 1+1+1+1 = Clarity

Exactly the opposite of my experience. First bought the HF cheapo. First AD helmet I ever tried. I think it must have been defective so I returned it and bought the cheapest Miller. Much better. Do wish I could step up to a larger viewing area with hopefully better optics someday. Just too low on the tool priority list. Trying to convince myself that I need a ‘spare’ hood for a buddy if they stop by.
