This bugs me. My brother and all other welders I know can see just fine two shades darker than me. This includes when I swap helmets with them.Last weekend I was doing some tig on .050 to .060 steel for my brother and could barely see it. He said while watching he could see on shade 11...I am also having trouble seeing low power mig. I have to put a bright light on the piece to see.Anyone else have to use a shade 8 to weld??? For the record, I'm only 42.Dave J.Dave J.Beware of false knowledge; it is more dangerous than ignorance. ~George Bernard Shaw~ Syncro 350Invertec v250-sThermal Arc 161 and 300MM210DialarcTried being normal once, didn't take....I think it was a Tuesday.
Reply:What are you able to see? At the right shade you should only be able to see the arc, the puddle, and very, very dim features of the surface you're welding on.
Reply:I weld on 8 or 9 when doing tig or mig, 10 on arc up to about 150amps then 11 can't see much at 12www.georgesplasmacuttershop.comPlasma Cutter and Welder Sales and Repairs--Ebay storeTec.Mo. Dealer Consumables for the PT and IPT torch's

Reply:I wonder if your real problem is that you need corrective lenses (cheaters) in your helmet. 42 is just about the age where the eyes start to change. Have you had your eyes checked lately?I remember one time that somebody was trying to teach me something in welding, and I had a borrowed helmet, and I could not see anything. The teacher just flat out asked me if I could see and I had to answer no. After that I always brought my own helmet. I keep cheaters in my helmet. I wear bifocals, but when I look through my helmet I look through the top of the lens, so my close up vision is terrible. The cheaters make a huge difference.As to why you can see with lighter lenses, like #9, with a lighter lens your pupil will contract, which increases your depth of field. Even if you need glasses, if the light is really bright you can see up close. The answer has to do with the physics of optics, including the concept of depth of field. If you ever learned to use the old SLR film cameras, you might have learned about depth of field, when you stop down the lens to F16 or F11 to get everything in focus.That is my theory, that your real problem is that you need glasses or cheaters for close up vision.RichardSculptures in copper and other metalshttp://www.fergusonsculpture.comSyncrowave 200 Millermatic 211Readywelder spoolgunHypertherm 600 plasma cutterThermal Arc GMS300 Victor OA torchHomemade Blacksmith propane forge
Reply:try a different color lens... I couldnt see to tig out of my auto dark helmet. so i got a gold lens and put it in a fixed shield. It works for me!
Reply:Richard, what you described about depth of field matches exactly with what I was told several years ago by one of the nations leading eye surgeons. He commented to me that the fact I had vision issues at night driving meant that it was probably time for me to look into getting a new prescription at least for driving at night.He said during the day my eyes closed down increasing my depth of field and allowing me to see better. At night when the pupils opened up, I'd need to squint, reducing the available light making it harder to see, as well as inducing eye strain and fatigue.Age matches pretty close to when I needed to get a new prescription for welding as well..No government ever voluntarily reduces itself in size.

Reply:Richard and DSWYour points make perfect sense and describe what I'm experiencing - lots of light and I can see. Sounds like a trip to the eye doctor this weekend.

Reply:Don't be afraid to explain in detail what issues you are having and why. My eye doc easily understood my need for specialized "work" glasses and my work prescription is set up to focus at 18" rather than what he normally sets glasses up for. If you don't clearly explain it to him, you'll probably get set up for distance vision vs what you need for welding.It's honestly not a bad idea to just get your eyes checked semi regularly anyways..No government ever voluntarily reduces itself in size.

Reply:Interesting explanation, i have a #9 in, and there is times its hard to see and i have noticed some eye aches once in a while. Guess i should make the trip as well been like 15 years since i last went.
Reply:I use a #9 on tig and mig, (hardly ever touch stick welding) and sometimes it seems too dark, but I get used to it. Everyone's eyes are different, so i find if I keep my lense clean and replace it every few months it works for me.

Reply:I'm 45. Same problem.A clean lens cover certainly helps, but I got a +1.5 cheater for my helmet and the problem went away. Same thing, the arc on DC tig isn't bright enough to see at low amps. I've even pulsed and it helped to see. Pretty much just guessing on the puddle, and helmet only goes to 9. Wearing a hoodie sweatshirt over the ack of your helmet helps too. Alot of light from behind your helmet will cause the problem to worsen.The funny thing is that aluminum has a brighter and larger tig puddle, so I'm actually using an 11 shade with no cheater even below 60 amps.As Raferguson said, the need for cheaters starts under low light conditions.

Reply:I've had to resort to wearing over the counter magnifiers too. I also am going to find a thin piece of soft flexible leather and mount it on the back of my helmet so it blocks the back light.

Reply:I use a 9 for TIG. I knew a guy once that used an 8 for DualShield.I usually use an 11 or 12 for DS.At 54, I also use prescription glasses to weld.

Reply:FWIW I adjust mine accordingly to the ambient background light, #10 in the dark recesses of the shop & #11 in direct sunlight. Arc air #12. Had catarac surgery couple of yrs back, really helped night vision, got rid of the halos around oncoming headlights.REAL TRUCKS DON'T HAVE SPARK PLUGS
Reply:I had a lot of problems seeing and tried various visual aids before coming up with a satisfactory solution. First I tried a cheater lens and that worked OK for some things. I finally tried a pair of prescription safety glasses and things got a lot better, but since my prescription is progressive bifocals, I had a heck of a time with overhead stick welding. I just couldn't get that small "reading" area focused on the work area. Then I finally found a solution that works for me. A good pair of safety glasses that has my "reading" prescription in the full lens. NOW I can see the puddle in all positions. But then I am 68. Your solution might be very different. I think that you are on the right track though. Have your eyes checked and get the best corrective lenses, then adjust the lens shade on your helmet.
Reply:I don't want to beat this subject down but this is funny because what he describes is exactly what all of us 40plus people go through. The other day i was watching some welding from a distance and when i started welding i noticed i couldnt see the puddle. I bought a new helmit and cheaters what a difference. Sorry guy time to face the music.

Reply:It's not so focused in only at 9 or so inches from your nose like reading glasses are. You can focus from 9"-ish out to arms length.

Reply:It is all about focal length. The focal length is the distance at which you can see best with a particular lens. One time I rejected a pair of bifocals because the focal length was too close, they redid them and got the focal length where I wanted them. With the original ones, I would have had to have held the book about 18 inches from my head, too close.I have a couple of different cheaters for my helmet. One set forces me to get pretty close to the work, the other set has a longer focal length, so I can get back a little further from the work. Not a good idea to get really close to the work if you are stick welding, you end up breathing too much smoke.It may take you a couple of tries to get it right.If you work with your optometrist or opthamologist, and explain exactly what you want, they can help you. Think about what focal length that you really want. To put it another way, how far from your face do you want the welding arc to be.There are a lot of possible types of glasses, rather than the standard bifocals, etc. Airline pilots, who have to read the labels on switches above the windshield, have special glasses that have a small reading section at the top, so that they can read those little labels. I have been super-happy with just plain bifocals, I can see great at a distance, but still read close. I can read signs at twice the distance that my girlfriend can, with her contacts. Occasionally I need to look at really tiny things, which is when I get out my magnifier light.The cheaters are a good place to start, in that they are cheap, you can try a couple of different ones, and that will give you an idea where you want to be. You might solve your welding vision problem for $10 or so.Also, you can buy reading glasses at the supermarket, try on different ones, and get an idea what you need.Ultimately, you should spend the bucks, get the professionals involved, and get a pair of glasses that meet your needs. I generally use two pairs of glasses, a dress pair and a work pair with sideshields. I sometimes wear prescription bifocal sunglasses, with a very small reading section.One other tip, you don't have to get the line on the bifocals at the height they suggest. For my dress glasses, I have a smaller than usual bifocal reading section, works great. For my work glasses, I have a standard, (larger) bifocal reading section.Seriously, you can get anything you want or need, you just need to express your needs clearly.

Reply:Originally Posted by MinnesotaDaveA seemingly odd question, but yes they are blue.Dave J.
Reply:Originally Posted by 4sfedHere are conclusions from a couple different studies of eye color ... "The iris of blue eyes age more long term than brown eyes because of light and sun sensitivity wear and tear, cause many to need reading glasses sooner than darker colored eyed people""The darker the eyes, the more light is absorbed as light waves pass through the eye, and the less light is available to reflect within the eye. Light reflection (scatter) within the eye can cause susceptibility to glare (eg. sun or headlights) and to poor contrast discernment. Thus it seems that people with darker eyes may have better vision in high-glare situations"
Reply:I believe that the above suggestions are the way to go, but thought I would throw this in because I think it's pretty cool. Arc One has Auto Darkening Hoods out that have half shade increments, might help someone stuck between "its a little to light and its a little to dark". You can also "set" them for a certain shade at a certain amp and it will automatically darken or lighten if you change your machine setting.
Reply:I had not heard of Arc One! That is pretty cool.Let me throw my own eyeball experience into this.I always had weird night vision. I saw the halos at night. But what I always saw was starbursts at night. I thought it was just having glasses on. You know, like the light would distort when it hit my windshield and then a little more when it hit my glasses.Well, for my 30th birthday my wife got me lasix eye surgery. They mapped out my eyes and knew everything about them. Then they commented about me seeing starbursts. I couldn't believe someone KNEW! It turns out that my eyes do not dialate correctly. There is no cure and no fix. But if I am driving at night and I see the starbursts of street lights and headlights and tail lights, I can turn on the dome light in my truck and literally watch the starbursts shrink and disappear as my eyes contract due to the dome light. I find myself driving with the dome light on a lot just to improve my focus. Doesn't cause my eyes to tire like driving in the dark. I can only imagine what this eye problem does to my vision while I am trying to weld. If only my problem was as simple as some cheaters. Thank God for what you guys have. I do. It could be worse. I could be blind. But I am not.
