How to Read Your Eyeglasses Prescription

O.D (oculus dextrus) is for your right eye and O.S (oculus sinister) is for your left eye.

The “sphere” column indicates how near-sighted or far-sighted you are. A minus sign in the sphere column means that you are near-sighted and a plus sign means that you are far-sighted.

If you have astigmatism, your cornea is shaped like the back of a spoon, curved more on one side that the other. The “cylinder” column refers to the measurable degree of astigmatism of your central cornea. The orientation of the spoon shape can differ from person to person, for instance, like a spoon standing on the end or on it’s side.

The “axis” column describes the orientation in the degrees from horizontal.

Bifocal prescriptions are indicated with the number such as “+1.50 add”. This number, when added on the sphere column of the prescription, gives the strength of the near-vision part of the bifocal lens.

Insight Into Eyesight

Vision is our most precious sense.

Canadians report that they would rather lose the use of their legs, or even sacrifice years off their lives than lose their eyesight. Still, too many neglect having an eye examination for many years, for sight saving preventative eye car.

Consider this: Each year, 78,000 Canadians are diagnosed with age-related macular degeneration (AMD), a number which is expected to triple within the next 25 years.

Four conditions cause the majority of preventable vision loss that is occurring in Canada today: age related macular degeneration (AMD), glaucoma, diabetic retinopathy and cataracts.

Don’t be just another statistic! Come in for an appointment today!

Eye Care In Winter Wonderland

Jennifer S., an avid skier, asked us the following question at her recent eye health appointment at our Optometry Practice:

Question: How do I protect my eyes while skiing during the winter months?

Answer:

 

The greatest damage to eyes in the wintertime is Ultraviolet Light, particularly UV type ‘A’. Exposure to UV-A over time can lead to premature cataracts. Damage to the eye’s lens is cumulative and builds up quickly if one does not protect the eyes from this particular radiation. Also, glare from sunlight reflecting off the snow can be both blinding and damaging to the eyes.

Your best protection is to wear ONLY 100% UV-A Block Sunglasses and Ski Goggles. An objective way to find out about UV blocking is to use an instrument called an Ultraviolet Spectrophotometer (also called a “UV Meter“) which instantly analyzes UV blockage.

Visit our Practice today and have your sunglasses and ski goggles analysed with  our UV Meter (Free of Charge) for their true objective, UV-A protection ability. If your eyewear is not UV-A protective, it is doing you more harm than good!

Thanks very much for your good question Jennifer!

Insight Into Eyesight: U.V. Protection

You can hardly pick up a paper these days without reading about ultraviolet radiation. Actually, there are two types of UV. One type tans your skin; the other type, which burns your skin, can also burn the retina and cause cataracts.

When we are upright, our eyebrows help protect the eyes from direct exposure to UV, so we need only be concerned about reflected light. Water, sand and snow can all reflect UV light into our eyes. Since there are no known benefits to UV exposure, it makes good sense to play it safe and protect your eyes. This is especially true for sports people, who spend a lot of time outdoors,or on the water. Many authorities also contend that computer operators are at risk from UV radiation.

Insight Into Eyesight: TV and Your Eyes

Your favourite TV show is on the screen, but why is the picture out of focus? Maybe it’s not the picture. Maybe it’s your eyes. Watching TV for long periods of time can cause eye fatigue. But TV watching is not harmful to the eyes.

To give your eyes a break when watching TV, you should be sitting at least six feet away from the screen. One guide is to sit at a distance that is five times the width of the picture. And don’t sit in the dark. It’s not good for your eyes. There should be light in the room, but not bright enough to wash out the TV picture. Move the light of the TV so that is doesn’t cause a reflection or glare in the TV screen.
