Stronger lighting will be the answer for those that can not see well enough for number 3 or number 5 welding glasses.
Those are the shades that are going to prevent IR and UV damage to the eyes.
Some folks have never used either of those and have not come up with any damage to their eyes.
Others have only done a little work with boro without them and have come up with life long damage.
There is some evidence that those of us with lighter eye color are a little more susceptible but the potential for permanent damage is very real and not worth the risk when proper protection is cheaply available for the cost of the shades and increased lighting.
Human eyes get bad enough in the 8th and 9th decades without having worked molten glass at all so any prevention we can do now is going to pay dividends then.
It's only a hobby and no ones life is on the line so waiting to get the proper personal protection like good ventilation and eye wear is worth it in the long run.
