Another Technology Problem: Blue Light


Recommended Posts

Yes, E=hν. 


I wonder if there is evidence that seafarers suffer disproportionately from macular degeneration. One might expect it, perhaps. 

I never thought of that.  Maybe someone will.   I am remembering a pair of popular and expensive - $300 - sunglasses that I bought - definitely a believer that you get what you pay for.  I hated them.  Across the top part of the lenses was a blue reflection and I could see nothing through it.   We have a nice little family-owned shop here that sells sunglasses (not the above-mentioned ones), accessories to glasses and repairs eyeglasses.   I went in there with what I had bought.  He took a look and said "Let me show you something".  He pulled out a pair of $50 sunglasses that they sell.  They are perfect.  I feel my eyes relax when I put them on and I can see clearly.   You don't always get what you pay for.
