Types of Prescription Glasses
Single Vision Glasses: These are the most common type of prescription glasses. They have the same optical power across the entire lens and are typically used to correct nearsightedness, farsightedness, or astigmatism. They are ideal for people who require vision correction either for distance (like seeing an eye exam chart clearly) or for close-up tasks.

Bifocals: Bifocal glasses feature two distinct optical powers – one for distance at the top and one for near vision at the bottom. They are a traditional solution for people experiencing presbyopia, the age-related decrease in near vision. Bifocals can be identified by a visible line separating the two lens sections.

Progressive Glasses: These glasses offer a more advanced solution for presbyopia. Unlike bifocals, progressives provide a gradual transition between multiple lens powers, with no visible lines on the lens. They allow for clear vision at all distances – near, intermediate, and far.

Lens Coatings and Enhancements
Blue Light Filters: With the increase in digital device usage, lenses with blue light filters have become popular. They reduce exposure to blue light emitted from screens, potentially minimizing eye strain and improving sleep quality.
Anti-Reflection Layers: Anti-reflective (AR) coatings are applied to lenses to reduce glare, reflections, and halos around lights. This coating is especially beneficial for driving at night and for individuals who spend a lot of time in front of computer screens.
Hydrophobic Layers: Hydrophobic coatings repel water, making it easier to keep glasses clean. This feature is particularly useful for prescription sunglasses and for those who are outdoors frequently or engage in sports.
Choosing the Right Prescription Glasses
When selecting prescription glasses, consider your lifestyle, the type of correction needed, and personal style preferences. Prescription glasses come in various frame styles, from designer frames by Gucci, Ray-Ban, or Dior to more affordable options. Consult with an Optometrist, preferably one who is well-regarded in Calgary or your local area, to determine the best type of glasses for your needs.
The Role of Eye Exams in Prescription Glasses
Regular eye exams are crucial in determining the right prescription for your glasses. In Calgary and Alberta, the cost of an eye exam can vary, but many clinics offer comprehensive services that include tests for visual acuity, colour vision, and more. An accurate prescription ensures that your glasses effectively correct your vision and enhance your daily activities, whether it’s for driving, reading, or using digital devices.
Prescription Sunglasses and Specialty Lenses
Prescription sunglasses offer UV protection while correcting vision, making them a versatile choice for outdoor activities. Specialty lenses, like those designed for cycling, can provide additional protection and comfort for sports enthusiasts.
Caring for Your Prescription Glasses
Proper maintenance extends the life of your glasses. Use a recommended eyeglasses kit for cleaning and store your glasses in a protective case. Be mindful of your glasses' lenses, especially if they have additional coatings, to maintain their effectiveness and clarity.
Conclusion
Prescription glasses are a blend of function and fashion, playing a vital role in improving the quality of life for those with vision impairments. From single vision to progressive lenses, and from basic models to designer frames, there is a vast array of options to suit different vision needs and preferences. By understanding the different types of glasses, lens coatings, and the importance of regular eye exams, you can make informed decisions about your eye care.
