Peripheral Vision Testing

By | 2019-06-30T18:13:21-07:00 June 30, 2019|

What you call peripheral vision tests, doctors call central fields (CFs). As a science it’s known as perimetry. It tests your visual sensitivity 300 up, down, right and left. Truthfully it’s a 300 circular pivot around fixation (spot where you’re looking). 

Perimeters do way more than “check your side vision.” These overpriced digital contrivances can detect […]

Life, Death, Cataracts and Taxes

By | 2019-03-25T19:41:53-07:00 March 25, 2019|

Cataracts, just as death and taxes, are something everyone will experience. Of course if you die at age three, you’ll know nothing of taxes or cataracts for that matter, well, unless you were born with congenital cataracts.

Beyond the rather depressing scenario just described, some will not live long enough for cataracts. For some of us […]

Christmas and Clarity of Focus

By | 2019-01-23T22:08:50-08:00 December 20, 2018|

In eyecare clarity of focus is important. It can even change our lives this time of year, or so some say.

  • I’m settling for brown brackish brine. Woke-up too late for a good cup of coffee.
  • Woke up too late to brew coffee. Thankfully my Keurig provided a pretty fair substitute.

Both paragraphs describe the same […]

Treating Glaucoma With Marijuana

By | 2019-05-23T15:39:35-07:00 December 1, 2018|

I live in Washington State, one of the first states to usurp federal law and usher in legal “recreational” marijuana. Yet even before recreational marijuana we had “legalized” medicinal marijuana, the intricacies of which I do not understand, and I’m too lazy to research.

What’s interesting is that medicinal marijuana was already available in a prescription […]

Prescription “Cutting” Prevents Nearsighted Progression, Right?

By | 2018-11-26T19:34:43-08:00 October 30, 2018|

Through the years there has been a shortsighted allegory accepted among certain factions of America culture about shortsightedness (nearsightedness or myopia) itself.

It’s commonly whispered among parents that one of the causative influences of the progression of the condition of nearsightedness is the continual upgrading of their children’s prescriptions which lines the pockets of the optical […]

Palouse Lentils and Eye Care

By | 2018-10-29T20:38:17-07:00 August 16, 2018|

Palouse lentils have nothing to do with eye care – true or false?

The answer is FALSE.

If you turn a lentil sideways, you’ll see that its shape is similar to that of a magnifying glass.  The Latin word for lentil is “lens.”  Today the term “lens” is used to describe any transparent object used for optics. 

BUT […]

Dry Eyes, Pain and Diabetes

By | 2019-03-25T18:30:48-07:00 March 12, 2018|

Dry eye discomfort can be a nagging source of distraction. It’s certainly not the kind of agony you experience with classic migraines, root canals, kidney stones or fractured ribs, but ocular surface disease (OCD) can make an eight-hour work day seem like twelve on the chain gang. And, interestingly, dry eye management has similarities to […]

InfantSEE is a program launched in 2005 for those under the age of one year. Originally it was a study that was to last for just a year or two or three. It was so successful it has been perpetuated, and I do not know the American Optometric Association’s current stand on […]

And Just What is Wrong with Glasses, Anyway?

By | 2018-09-20T14:29:15-07:00 January 11, 2018|

I’m always amazed how so many people, usually adults, will tolerate radical inconvenience to avoid the benefit of glasses. Most are embarrassed by reading and driving glasses while insisting their sunglasses are a must.

REALLY? And why? Exactly what is this elusion all about?

It’s my experience that many refuse the help of glasses while touting the […]

The Holiday Bird

By | 2018-12-19T22:16:05-08:00 November 18, 2017|

As Thanksgiving rolls around so does the thought of turkeys. No – not those proverbial in-laws that show up around the holidays purely to contribute their unsolicited opinions. You know. The ones you call “turkeys.” Not those.

I’m talking about the bird that adorns the Thanksgiving table. But in fact, I’m even deviating from the turkeys […]
