"Buy a autodimming helmet"
I was considering this last helmet replacement... ( mine was probably 40 years old ).... and after looking at it I found that I did not want to go that way....
They do not protect your eyes instantly.... there is a tiny lag at each strikeup.... over the course of a day or week... or years... you may be getting too much UV light hitting your eyes...
Like hearing loss... eye damage is cumulative.
I say find a good fitting helmet with as dark a lens as you can use... and let high tech improve you life in other areas...
