Sun protection is essential all year round, especially in a city like Calgary, where the sun’s rays are reflected off buildings, roads, and snow. If you’re buying sunglasses in Calgary, you might be unsure whether to choose polarized or non-polarized lenses. Choosing the right sunglasses is based on your lifestyle, eye health, and visual comfort. The appropriate pair can help protect your eyes from UV damage, eliminate glare, and enhance clarity, provided you know what to look for.
What Are Polarized Sunglasses?
Polarized sunglasses contain a unique filter that shields you from horizontal light. This is the light that is reflected off surfaces such as water, pavement, or metal. It produces glare, which makes it difficult to see. Polarized lenses reduce glare, creating a more relaxed feeling for your eyes. They are particularly beneficial if you commute frequently or have frequent exposure to water. The filter in the lenses enhances colour contrast and improves overall visual acuity in sunny environments.
When to Use Polarized Lenses
If you spend a great deal of time outdoors, polarized sunglasses might be ideal for you. These are perfect for boating, fishing, golfing, skiing, or driving long distances. Glare can cause eye strain, headaches, or a momentary loss of vision. Polarized lenses eliminate that issue. They help you see better without needing to squint, particularly during direct sunlight or when it rains. For sensitive eyes, this added protection can provide significant relief. If you’re unsure, try it on and see how you like it.
What About Non-Polarized Sunglasses?
Non-polarized sunglasses do provide UV protection, but they don’t reduce glare as effectively as polarized sunglasses. They darken the vision but don’t filter horizontal light. These lenses are more affordable and can still protect your eyes against sun damage. Some people prefer non-polarized lenses when they need to see digital screens, such as on a plane, while using GPS or working on a phone or laptop. Polarized lenses can sometimes make these screens harder to read.
Style and Prescription Options
Most individuals desire a balance of style and function. Fortunately, both polarized and non-polarized sunglasses are available in a wide range of frame styles, tints, and prescription strengths. If you wear glasses daily, you can have your prescription included on either type of lens. You can also have photochromic lenses that self-adjust to light. For Calgary shoppers seeking sunglasses, most optical shops now offer custom solutions, allowing you to choose between style and protection.
Why You Need an Eye Exam
It makes sense to have an eye exam in Calgary before purchasing new sunglasses. A recent exam will ensure your prescription is valid and your eyes are healthy. An optometrist will also inform you of the most suitable lens type for your vision requirements. They will examine you for light sensitivity, UV risk, and other factors that will influence your choice between polarized and non-polarized lenses. Missing an exam can result in choosing sunglasses that don’t even safeguard your eyesight as required.
The Calgary Climate Factor
Calgary’s sunny days and seasonal changes necessitate sunglasses that perform well in diverse conditions. Snow reflects light in winter. Long sunlit days require good UV protection in summer. Wind, dust, and instant glare require tough, high-quality sunglasses. Whether you’re heading onto the trails, cruising mountain roads, or strolling downtown, your sunglasses must keep up with the light conditions you encounter daily.
Choosing between polarized and non-polarized sunglasses in Calgary depends on your daily habits and eye care needs. Both types protect your eyes, but one may offer a more comfortable viewing experience. Don’t forget to book an eye exam in Calgary before making your final decision. With the proper guidance, you’ll enjoy better vision, eye comfort, and peace of mind all year long.
