After Daylight Savings Time, More Darkness on Your Morning Drive May Mean More Vision Problems

It’s daylight Savings time this weekend which means you will turn your clock forward, resulting in a little more dim light driving on your morning drive.

A survey done in 2007 found that 32% of drivers say that they have difficulty seeing all or most of the time while driving in the dark.  20% had trouble seeing turns in the road and 22% had trouble judging distance while driving at night. 61% said that headlights from oncoming traffic is bothersome and 48% experience glare while driving at night.  73% said that correcting vision problems would improve their ability to drive at night.  None of this is is surprising.

The surprising stat was this:  Only 27% talked with their Optometrist about these problems.

If you have having trouble seeing at night, book an eye appointment and ask what could be done to improve your night vision.

Nikon Lenses Make Your Iphone Faster

If I was to ask you what business Nikon was in, you would probably say cameras, or perhaps eyeglass lenses or perhaps telescopes…but you would be wrong.

A little known fact is that one of Nikon’s main operations is the manufacturing of steppers.  Nikon is the second largest stepper supplier in the world.  Now if you are like me, you probably have no idea what a stepper is.  A stepper is the device that is used in the complex process of photolithography, which creates the millions of microscopic circuits on silicone chips.  These chips are the building block of virtually every electronic device you use.

Steppers use dozens of lenses to minify the circuit patterns onto a silicon chip.  The most important feature of a stepper is a lens that provides optimal transmission and focus of light through the lenses and that is why Nikon spends millions of research dollars in developing the best optics and the best coatings they can.  This is why they are a leader in the field of steppers.

Now the great news for you and I is that Nikon has decided to apply this research to their camera and eyeglass lenses, helping us see the world clearer.

I can tell your IQ by looking in your eyes

A study published in the May 15, 2013 journal Psychological Science reports an association between retinal vessel size and IQ.  Now considering I look at retinal blood vessels all day long, this article intrigued me.  The study looked at over 1000 individuals and found that after accounting for all sorts of extenuating circumstances, those with larger retinal vessel size had lower IQ’s and those with smaller retinal vessel sizes had higher IQ’s.

Armed with my new found knowledge, all I need are 2 retinas to compare.  So I chose mine of course and who else?   My wife of course, Dr. Friesen.


My retina is on the left and her’s is on the right.  And I proceed to measure and average the retinal vessel size, just like investigators did in their study….one eye averaged to be 7.85 pixel vessel size, the other 6.5.

So who had the larger vessel size?

I think you already know.

Ideas for Science Projects

I was out for dinner the other night and we were talking with friends about Kids Science Projects, so I thought I would jot down some projects related to the eyes that might work well as Science Projects:

  • Colour Vision
  • How The Eye Works/How a Camera Works
  • 3D Vision/Stereopsis/Magic Eye Pictures
  • Safety Spectacle Lenses
