All eyes have different views.
Some need more or less shade, some like green lenses, some orange.
For me, the most clairity was gained by using GLASS lenses that have a highly reflective gold coating on the side facing the weld.
They are more expensive but when you live under the hood and your job depends on the quality you produce, you need the finest supporting equipment.
Try one, compare it to a std weld lense.
There is more clarity with a gold plated glass 12 than a std glass 10.
The quick darkening lenses are nice for tight spots where you cant drop your hood, also when you need exact initial start placement.
However they may not provide optimum viewing. Had several of them so poor performing, was cause for concern with eye protection.
