A Quick Word About Me…

Born and raised in beautiful, southern California, I received my bachelors of science in Psychobiology at the University of California, Los Angeles, in 2004. From there, I went on to study optometry at the University of California, Berkeley — class of 2009. I am fully licensed to practice optometry in the state of California, and am TLG certified (Therapeutic Pharmaceutical Agents, Lacrimal Irrigation & Glaucoma). I am currently practicing as a staff optometrist at Clear View Optometry, in Rancho Cucamonga, 5 days a week.

During my time off, I like to read — stuff mostly related to optometry, technology, and “getting things done” — and simply spend time with family and friends.

What is Astigmatism?

Some patients may be more than a little concerned when I tell them they have astigmatism. A recent, informative article on Medical News Today answers the question as to what astigmatism actually is, and provides more detail than any patient would care to know about the condition. Here’s a quick tidbit that gets to the meat of the question:

Astigmatism is an eye condition with blurred vision as its main symptom. The front surface of the eye (cornea) of a person with astigmatism is not curved properly – the curve is irregular – usually one half is flatter than the other – sometimes one area is steeper than it should be.

When light rays enter the eye they do not focus correctly on the retina, resulting in a blurred image. Astigmatism may also be caused by an irregularly shaped lens, which is located behind the cornea.

I’ve found the easiest way to explain it to my patients is to tell them that, with astigmatism, the eye (or its front surface) is not perfectly round in shape — it may be squished in one direction or the other, preventing light from focusing at a single point in the back of the eye; instead, light focuses at mutiple points (or a line), causing blur. Glasses allow us to correct that by providing different prescription powers in the different meridians of the lens. I often explain to patients that astigmatism is so common that I’m a little surprised when I run into a patient that doesn’t have any. Read the article for more detail on the subject.

The Dreaded Eye Exam

An eye exam can be a pretty traumatic experience for some people. For others, it may just be frustrating. Why exactly are we poking and prodding at your eyes so much, when all you wanted was a pair of glasses? I think if we can clarify exactly what goes on at the eye doctor’s office, it can all be a little less scary, and a lot less exasperating. When you see your optometrist for an eye exam, the doctor will evaulate your visual system in four general areas.
