Fight Optical Sale Illusions

Wednesday, February 29th, 2012

JC Penney recently changed its pricing strategy, aiming to eliminate their practice of what Ron Johnson (CEO) calls “fake prices”.  I can only hope that chain opticals will someday take the same approach.

For years, chain opticals have manipulated sales and discount vision plans to create an illusion of savings for consumers.  The sales and vision discounts are generally just reductions from regular prices that are set artificially high to begin with.   It’s a common marketing ploy to make people believe they are getting a bargain.

So how do you get the best eyeglasses?

1.  Lenses first.

Your doctor is your best resource for recommending which brand and type of lens is best based on your individual vision needs, past history, and current prescription.  I recommend Zeiss lenses most often for their commitment to having the best ophthalmic lenses.

2.  Frame next.

Frames truly represent our personality and run the gamut of utilitarian to high fashion.  An optician can help you make sure the frame you like is compatible with the lenses you require.

3.  Value.

Consider the quality of the eyeglasses, the expertise of the staff, and the warranty before your purchase.

Read On If You Have Night Vision Trouble

Friday, February 17th, 2012

Nothing is perfect, including your eye.  As light enters the eye it is altered by imperfections in the cornea, lens, vitreous, and retina.  We refer to these alterations as aberrations and the vast majority of aberrations are caused by the front surface of the eye called the cornea.

Most aberrations are typical and refractive in nature such as nearsightedness, farsightedness, and astigmatism.  These are called low order aberrations and can be compensated for with ordinary eyeglasses and contact lenses.

Other aberrations are less typical such as coma, trefoil, and spherical aberration.  These cannot be compensated for with ordinary glasses and contact lenses and are called high order aberrations.

We can now measure many of these aberrations with an instrument called an abberometer.  I find that about 10 to 20 percent of people I measure have significant nighttime higher order aberrations.  If you have night vision trouble you probably have significant higher order aberrations under low light conditions and you should be measured!

Based on these advanced measurements a pair of custom eyeglass lenses (free form/individual lenses) can be made to compensate for both your low order and higher order aberrations to improve acuity and contrast; especially in low light or nighttime conditions.  At this time we are not able to compensate for all higher order aberrations, but our abberometer has a simulation mode which can accurately predict who is able to benefit from this new technology.
