I use
Zeiss Skylet glasses and usually a more wrap around frame with them that block out most of the light entering from the side. Have used them since my gliding days over 20 years ago, since they block most of the blue light they enable a much better cloud identification and a much clearer view. One thing to note is, on switching from the 737 to the A320 i had to switch from 90% absorbance to 75% as the airbus screens are so very bad compared to those used by Boeing. Not only size, but also the available range of brightness. In total those kinda glasses are not cheap, i usually pay from €600 upwards, my current set is over 1k as i am getting into the age where i need multifocal lenses...
