Well I went to walmart to search for prescription saftey glasses (because I cant see far away worth a damn, like anything past my elbow is blurry) and found a sweet pair that is tight fitting and has a rubber gasket around the perimeter of each lense. I was told these are usually worn for motorcycle riding. I'm not sure why they are not more popular for fabricators or even construction workers. While explaining to the eye dr why I came in she said she didnt even know they had prescription safety glasses!
So the lenses are 100% UVA and UVB blocking. This should mean no more chance of burnt corneas or eye irritation.
HOWEVER, what I am concerned about is does this also eliminate possible deterioration of the retina over time caused by the blue light spectrum?
In my research there has been conflicting information and the doctors Ive went to do not seem well educated in this field to answer the question. My confusion is that the lens are supposed to be 100% UV protectant by the material it is made from, this means tint does not matter. I opted for clear, however, as I researched I found that to protect from retinal damaging blue light wavelengths created by welding reflections under the hood, they advise a colored lense such as red or yellow that will filter out the harmful blue light...
I am fine getting a yellow or red tint, but I need an explanation as to WHY, if the clear lense itself is claimed to be "100% UV blocking", why do other sources say you need to have it color tinted to filter out the blue spectrum of UV light? The problem is I dont know who to believe or even who to ask.
Straight from old reliable wikipedia:
Depending on the manufacturing technology, sufficiently protective lenses can block much or little light, resulting in dark or light lenses. The lens color is not a guarantee either. Lenses of various colors can offer sufficient (or insufficient) UV protection. Regarding blue light, the color gives at least a first indication: Blue blocking lenses are commonly yellow or brown whereas blue or gray lenses cannot offer the necessary blue light protection. However, not every yellow or brown lens blocks sufficient blue light.
Thats about as clearly stated as my pond water is after running my jeep through it. So yellow lenses may or may not block blue light. So how do you know if it does?
