The Solar Eclipse and Eye Health

By | August 8, 2017|

My radio ads direct you to this site concerning the eclipse and eye health. My comments concerning the upcoming eclipse are about viewing it in and around Pullman, Washington. Those viewing elsewhere should get their information from experts within those areas. You can find good information at these sites: NASA (the best), […]

I’m Allergic To Contact Lenses

By | May 4, 2017|

Dear Dr. David,

I’ve tried contact lenses several times. I always develop an allergy to them. Are there any contact lenses which do not cause allergies?

Sincerely,

Miss Frustrated

 

All contact lenses are hypoallergenic*, because all contact lens materials are inert and immunologically neutral. So, in short, contact lenses materials do […]

Wearing My Brother’s Contact Lenses

By | April 14, 2017|

My brother’s away at college. His contacts feel fine, and I see great in them. I can easily order new ones online. What’s wrong with that?

Respectfully,

Lil’ Bro

Well, Lil’ Bro, what if the power is wrong?

Your vision will either blur and/or fatigue. Although uncomfortable, neither causes […]

The Foresight of a Backward Glance

By | February 1, 2017|

Radio and TV ads of late frequently tout the benefits of refractive surgery and how it has improved people’s lives. Refractive surgery is the general term for surgical correction of nearsightedness, farsightedness etc. In fact one such ad in our area says that refractive surgery eases human encumbrance. These ads are true. LASIK is wonderful […]

Winter Dry Eyes

By | November 28, 2016|

If you suffer from dry eyes, it’s about to get worse as winter creeps in.

The thing about cold air is that even at 100% humidity it doesn’t hold much water.  For example, if it’s 20º F. outside and the humidity is 100%, and you warm that air up to 70º F. in your home – […]

Scleral Contact Lenses

By | October 28, 2016|

Let’s consider the comfort of firm vs. soft contact lenses. A significant number find both firm and soft contact lenses uncomfortable, a few find firm contact lenses more comfortable, and a greater number find soft contact lenses more comfortable. Some of the comfort experienced by soft lens wearers is because soft lenses are larger.

Let’s consider […]

Streaming the Blues

Your eyes, in combination with your brain, can see and understand light waves by interpreting them as color. Reds are longer wavelengths while blue and violet are shorter. Light is energy emanated in electromagnetic waves which are measured in nanometers (nm) or billionths of a meter. The longest electromagnetic wavelength that a human can see […]

Myopia Epidemic, Worldwide

By | October 15, 2015|

Throughout the world there is an epidemic of myopia (nearsightedness).

According to Dr. Jeffery Cooper, a myopia researcher, in the early 1970s there was about 25% myopia among U.S. young adults. Compare that to 41% in 2004. Genetics cannot explain such a change!

Taiwan is now 80% myopic. In South Korea in 1955 myopia affected 18%. In […]

Dry Eye Syndrome: Introduction

By | April 20, 2015|

At one time we eye people worried about making thinner lenses for high prescription glasses. Later we fretted over the rising incidents of cataracts and eye disease in our aging American population. Then we agonized over LASIK. Currently the nagging conundrum is chronically uncomfortable eyes – inappropriately labeled dry eye when what’s really meant is […]

Macular Pucker

By | February 2, 2015|

Macular pucker is a protracted visceral stress condition common to bungee jumpers.

Sorry, just kidding.

Macular pucker is actually an eye disorder – an anomalous facet of a normal happening.

When we are born the inside filling of our eyes is a clear but firm jelly called the vitreous. The vitreous is contained in a membrane which adheres […]

Age Related Eye Disease Study (AREDS) 2

By | June 16, 2014|

Just as with AREDS, I believe AREDS 2 has a multitude of problems. Instead of studying just one or two variables the study has as many as six. Then it is stated over and over again within the abstract, methods and results that there is no true placebo group. Why not simplify the project so […]
