Learn how Transition Lenses can help you see things the way they were meant to be seen. If you have poor vision and opt for glasses, you know the danger inherent in taking them off. Your poor specs end up lost or you’re walking into walls. When the sun is shining, this can be a problem. You’re either blinded by the light or constantly switching between glasses and prescription sunglasses.
To combat this conundrum, many people opt for photochromic lenses, also known as Transitions lenses. The lenses adjust to changes in light to optimize eyesight. When you’re exposed to ultraviolet light, the lenses
Sunglasses aren’t just a summer staple. In fact, optometrists recommend wearing sunglasses year round for optimal eye health. Tom Cruise and Audrey Hepburn were on to something. Not all lenses are created equal, however. Polarized lenses offer a host of advantages that should be considered when purchasing eyewear.
When sunlight is reflected off of water, snow, windshields, passing cars, and other bright surfaces, it causes visual noise or that pesky glare. Light travels in all directions and standard sunglasses filter light equally, yet polarized lenses filter the light selectively and absorb light waves from various angles, while also protecting against harmful UV rays.
Hello my bespectacled friends. A lot of people visit our store wondering why their glasses pinch, sit crooked on their face, slide off, or even feel off-center. These are all symptoms of the dreaded improperly fitted glasses. But don’t reach for the tape or try to bend your glasses into shape just yet. We are going to solve five common issues associated with improperly fitted glasses.
One minute you’re lost in your daily newspaper and the next minute everything is a blur. This frustrating issue is typically caused by the temples not sufficiently curving behind the ears, the nose pads on metal frames not being fitted to suit the client’s unique bridge shape, or in some cases the frame is just too tight against the side of the head forcing the glasses forward. I have some quick fixes to ensure your glasses stay put.
One of the top questions that I get at The Spectacle Shoppe is, "What is an Astigmatism"? In short, Astigmatism is a common type of refractive error. It is a condition in which the eye does not focus light evenly onto the retina -- the light-sensitive tissue at the back of the eye. Instead of creating one focus point, the rugby ball shaped cornea creates multiple focus points (see diagram). To help illustrate further, I've sourced The National Eye Institutes explanation of the facts on astigmatism.
Refraction is the bending of light as it passes through one object to another. Vision occurs when light rays are bent (refracted) as they pass through the cornea and the lens. The light is then focused on the retina. The retina converts the light-rays into messages that are sent through the optic nerve to the brain. The brain interprets these messages into the images we see.
As the weather begins to change I tend to start thinking about sun protection. For my family this means hats, sun screen, UV protective clothing for my toddler and sun glasses. I think it’s safe to say that most people are now fairly aware of the damaging effects of ultra violet radiation. I’m not so sure that everyone includes protective eyewear on their sunny day checklists. In fact today as I look out our office window there are very few people walking by with appropriate sun eyewear.
As a Licensed Optician I love interacting one-on-one with clients. One of the most common complaints that I hear about is dry eyes from contact lens wear.
I've got a few handy tips to help with this problem, but in order to get there I need to first tell you about the composition of tears and the role tears play in eye health.
Tears are made up of 3 layers: lipid, aqueous and mucin. These 3 layers each have a part to play in preventing dry eye. The lipid (fatty) layer prevents evaporation. The aqueous or lacrimal layer makes up most of the volume of the tear film. This layer carries nutrients, washes away unwanted or dangerous bacteria or foreign objects. The mucin layer is the glue holding the tears to the cornea. If there is a problem with any of these layers which prevents optimal functioning then you end up with dry eyes.
