I’ve been promising this one for a while.

The Q&A video isn’t perfectly clear on a few key points.  I blame the giant ants.

  1.  The main way to address blur horizon is always diopters.  Lux is just “fine tuning” blur horizon, in some scenarios.
  2. This works best in the 300-1,200 lux range.  Higher lux is too bright, and sunglasses are just bringing light down to a manageable range in the first place.  Any lower and it’s just too dim, creating unnecessary eye strain.
  3. Don’t go being behind sunglasses in dimly lit indoor spaces, just because of this side note suggestion.
  4. This is absolutely an advanced student topic.  If you’ve already been doing all the actually important things for a while, and are ready to play with little tweaks, this is for you.  You’ll also want to be able to quantify what you experience by using centimeter and log.
  5. This is of course and as always, not optometrist advice or prescription advice or any advice in general.
  6. Don’t use this for close-up distance tweaking.  Meant for distance vision and outdoor use primarily.

As always, thumbs it if likes it.
