I went to this optician to get new glasses, and they were helpful and friendly. When I had to return to get the glasses adjusted, the worked quickly to get them right. I'd be happy to recommend then to anyone looking to get new specs.

Billie, optometrist Shawn Medway and all staff were just great and treated me with kid gloves. Dr. Shawn Medway was very diligent in ascertaining my correct vision and even brought me back in for a second check of something that concerned him - luckily there was nothing to it. Billie was just a standout ! When I saw her to get my new frames, I saw she'd picked one when I walked through the door, and wouldn't you know it, but I loved them at first sight! When I returned for my fitting, etc. Billie was always there to help me out with a great sense of humour we both shared. I would definitely go back to Crescent Heights for my visual needs.

This Optometrists are the best. The staff are all pleasant and helpful. The Doctor is so thorough in checking my eyes; in fact I was referred to him from my family doctor a few years ago. Their products are top of the line at comparable prices. Highly recommended!

Eye Charts: The Writing on the Wall

Part of your vision test will include a glance at the all-too-familiar eye chart. Read on to learn the philosophy and history behind those shrinking letters.

According to the Seattle Times, the best-selling poster in the United States isn't of Indiana Jones or the cover to Pink Floyd's Generic World Map. It's the eye chart, those iconic rows of decreasingly sized letters that grace optometrists' offices throughout the country. Aesthetics aside, the ubiquitous chart primarily tests visual acuity, which the American Optometric Association summarizes as "the clarity or sharpness of vision." Patients typically stand around 20 feet from the wall, cover one eye, and identify the smallest row of letters they can individually distinguish. Commonly, this boils patients' visual acuities down to a fraction in which the denominator represents how many feet away a person of normal visual acuity could stand while still discerning the letters with the same level of clarity as the patient. In other words, 20/40 vision means the patient needs to stand 20 feet away to make out the same size letters as a person with standard vision can from 40 feet.

These fractions were the brainchild of Herman Snellen, a Dutch ophthalmologist who designed the first popular rendition of an eye chart in the 1860s. The original versions of Snellen's chart included nine letters—C, D, E, F, L, O, P, T, and Z—as optotypes—a term for standardized symbols used to test vision. However, there was room for improvement in Snellen's design; the spacing wasn't quite standardized, and different versions incorporated serif as well as sans serif fonts. Over the years, the Snellen chart has adopted more uniform spacing and cleaner optotypes, and a few alternatives have sprung up for use in other settings. For instance, scientists prefer a chart designed by two Australian optometrists for its logarithmic progression of letter size, and one variation simply orients the single letter 'E' in different directions, making the test easier for patients who are illiterate or unfamiliar with the Roman alphabet.

For all their value, eye charts are still only capable of assessing visual acuity, not vision in general. Full eye exams almost invariably include a staring contest with an eye chart, but optometrists also use different tools to test everything from peripheral awareness and depth perception to focusing ability and colour vision.
