Glaucoma: Avoid Irreversible Vision Loss

The other day, I was having lunch with a friend who had just gotten her yearly eye exam at her local optometrist. Besides her expected nearsightedness and some trouble with dry eyes, her eye doctor did not have much to tell her, but that didn’t stop her from worrying over her husband. He refuses to have an eye exam, and he’s in his mid-forties. My friend asked me if she was worrying for no reason; after all, her husband’s vision has seemed to be fine for years. My response to my friend was the inspiration for this blog: hadn’t he ever heard of glaucoma, the leading worldwide cause of irreversible vision loss? Keep reading to learn about this “silent thief of eyesight” and how regular eye exams can prevent it from stealing your vision. What is glaucoma? As briefly discussed in a previous blog post, glaucoma describes a group of conditions that cause damage to the optic nerve, which is a paired nerve connected to both eyeballs and responsible for relaying images from the retina to the brain. Without a properly-functioning optic nerve, these images cannot reach the brain, but how does damage to the optic nerve occur? The optic nerve is made up of millions of delicate nerve fibers; when these fibers are damaged, it will have a negative effect on your vision. Some experience a loss of peripheral vision followed by a progressive darkness while others develop blind spots from the damaged nerve fibers. How these fibers get damaged is not fully understood at this point, but we do know that both high eye pressure and low...

Why Are Regular Eye Exams Important?

We all have long lists of things we need to do in order to stay healthy. We visit the dentist twice a year, take multivitamins every morning, commit to exercise routines and nutritious diets, and much more. With so much to constantly think about, it can be too easy to let certain things slip through the cracks, especially seeing your optometrist on a regular basis. Typically, it is recommended that you get an eye exam at least once a year, especially if you’re over the age of forty or are a contact lens wearer. Keep reading to discover the importance of having regular eye exams. The Importance of Regular Eye Exams Accurate Prescription When you consider the purpose of an eye exam, your first thought is likely to get an accurate prescription to improve your poor vision, and this is definitely an important aspect of an appointment with your optometrist. Only a professional optometrist is going to be able to provide you with an accurate prescription, whether you suffer from nearsightedness, farsightedness, or an astigmatism. Check for Common Eye Conditions Besides the obvious purpose of providing patients with accurate prescriptions, optometrists also check your eyes for other common eye conditions. During your eye exam, your optometrist will be keeping an eye out for the signs of the following conditions.   Cataracts The lenses in your eyes are made up of water and proteins, which allows light to pass through and create a clear image. These proteins can begin to clump together over time (this is a common effect of aging), causing part of the lens to cloud over. These...

What to Expect During Your Eye Exam

At Vision Care Centre of Langley, we know that having an eye exam can be a cause of stress for many people. That’s why we’d like to provide you with a short overview of what you can expect during your visit to the eye clinic. We’ve previously discussed the steps you can take before your eye exam that will help to lower your stress as you make a visit to the eye clinic. Today, we would like to focus on what actually happens during an eye exam. Oftentimes a glaucoma test is necessary. Instead of the air puff test (which everyone dreads), we use applanation tonometry, which is the gold standard to measure your intraocular pressure. Occasionally, the optometrist will check your peripheral vision. The doctor will also generally perform a test in which one eye at a time is covered, allowing him or her to observe how your eyes move together. Many people often think of the test in which your eye doctor will flip through various lenses in order to determine which, if any, prescription is required for you. Dilation of your eyes may also be needed. An eye drop is put in your eyes in order to dilate your pupils and perform this test. Sometimes other procedures will be necessary and your doctor will discuss these tests with you if you require them. If you have questions on these or any other procedures you might encounter during an eye exam, please feel free to contact us and we’d be happy to go over the basics of an eye...

How Many Megapixels is the Human Eye?

If you’re the proud owner of an iPhone 6s, you probably know that it features a 12-megapixel camera, but do you know how many megapixels are in a human eye? According to the math, even though your eyes don’t perceive pixels in the same way a digital camera would, a human eye would be the equivalent of a 576 megapixel camera. That’s why it’s so important to keep your eyes healthy. You know what a fancy digital camera with a lot of megapixels costs and that’s an investment you’d want to protect, so why not do the same for your eyes by seeing an optometrist? Whether you suffer from nearsightedness, farsightedness, an astigmatism, or any other specific eye condition, the optometrists at Vision Care Centre Langley can give you a professional consultation. Our optometrists can go into detail and explain any eye condition you might have or irregularity that they see. An added benefit of regularly seeing an optometrist is that it can also help to keep you healthy as optometrists can aid you in detecting high blood pressure, vascular disease, diabetes, high cholesterol, and even some cancers. You’d pay to have your new digital camera serviced to be certain that your shutter is working properly or that your lens isn’t dented or scratched, so be sure to take care of your eyes in the same way. See an optometrist to be sure that the beautiful 576 megapixel cameras you were born with are in good working order. Contact us to set up an appointment...
