Best Blue Light Blocking Glasses: What to Buy and What to Skip

What Makes Blue Light Glasses "Good"

Not all blue light glasses are created equal. The difference between a $15 pair from Amazon and a quality pair from your optician comes down to three factors:

Filter Type

In-lens filtering embeds the blue light absorbing material directly into the lens during manufacturing. The filter is consistent across the entire surface, won't wear off, and doesn't affect other coatings. This is the better option.

Coating-based filtering applies a reflective layer on top of the lens that bounces blue light away. It's less consistent, can wear off over time, and sometimes creates a distracting blue reflection on the outside of the lens.

Filter Strength

Lenses that filter 20-40% of blue light are ideal for all-day wear — they reduce exposure without noticeably changing colour perception. Lenses filtering 50%+ have a yellow/amber tint and alter how colours look on screen, making them better suited for evening use only.

Lens Quality

The optical clarity of the base lens matters more than most people realize. Cheap blue light glasses often use low-quality plastic with poor surface finish, creating distortion and eye strain that defeats the purpose. Quality lenses from an optician like Charm Optical provide clear, distortion-free optics with blue light filtering built in.

Prescription vs. Non-Prescription Blue Light Glasses

If you already wear glasses, adding blue light filtering to your prescription lenses is the obvious choice. You get vision correction and blue light filtering in one pair, with professional fitting and quality lenses.

If you have perfect vision, non-prescription blue light glasses can work — but invest in a quality pair from an optical store rather than the cheapest option online. Low-quality lenses create more problems than they solve.

When comparing options, consider your daily routine and visual priorities rather than just price. The "best" choice is the one that matches how you actually use your eyes throughout the day. Someone who works on a computer for 8 hours has very different needs than someone who primarily drives or reads. An honest conversation with your optometrist about your daily visual demands will point you toward the right option far more effectively than online reviews.

Keep in mind that you're not locked into one choice forever. Many people own multiple pairs for different situations — dedicated computer glasses for the office, progressives for daily wear, and prescription sunglasses for driving. Charm Optical carries 500+ frames across every style and price point, making it easy to build a collection that covers all your visual needs. Their opticians can advise which lens types pair best with each frame style. Same-day glasses are available for many single vision prescriptions.

Top Blue Light Lens Options in Canada

Zeiss BlueGuard

In-lens blue light filtering built into Zeiss's lens material. Blocks up to 40% of potentially harmful blue light while maintaining colour accuracy. Available through opticians who carry Zeiss lenses.

Essilor Eyezen / Crizal Prevencia

Essilor offers both in-lens (Eyezen) and coating-based (Crizal Prevencia) options. Eyezen lenses also include a slight boost in the lower portion for comfortable screen viewing — a smart feature for people who don't yet need progressives.

Hoya Blue Control

Coating-based blue light filter with strong anti-reflective properties. Good option if your optician works with Hoya lenses.

All major lens brands are available through independent optical stores. Your optician at Charm Optical can recommend the best blue light lens option based on your prescription, daily screen time, and budget.

The best way to evaluate frame styles is to try them on in person. Photos and online try-on tools give a rough idea, but they can't replicate how a frame feels on your face — the weight distribution, the temple pressure, and how the nose bridge sits. These comfort factors matter more than aesthetics for glasses you'll wear 12+ hours a day.

Charm Optical in Edmonton carries over 500 frames from brands including Ray-Ban, Oakley, Versace, Tom Ford, Burberry, Prada, and Dolce & Gabbana. Their opticians help you narrow down the options based on your face shape, prescription requirements (especially important for progressives), and personal style preferences. With same-day service for many prescriptions, you can walk in and walk out with new glasses the same day.

What to Look for When Buying

A practical checklist:

• Check the filter percentage. Reputable products state how much blue light they filter (e.g., "blocks 40% of blue light between 415-455nm"). Products that just say "blue light blocking" without specifics may filter very little.
• Look for in-lens vs. coating. In-lens is more durable. If the product has a visible blue or purple reflection on the outside, it's coating-based.
• Verify anti-reflective coating is included. AR coating reduces the internal reflections that cause glare — especially important for screen use. Cheap blue light glasses often skip this.
• Consider your screen habits. If you're on screens less than 4 hours daily, the 20-20-20 rule and screen brightness adjustment may be enough. Heavy screen users (6+ hours) benefit more from filtering lenses.
• Don't overpay for gimmicks. Some brands market "gaming glasses" or "computer glasses" at premium prices for the same filtering technology available as a standard lens add-on from your optician.

Blue Light Glasses and Insurance Coverage

Most Canadian insurance plans cover prescription lenses including blue light filtering as part of your standard lens benefit. The blue light add-on typically falls within the "lens upgrade" or "coating" portion of coverage.

Charm Optical bills directly to Alberta Blue Cross, Canada Life, Desjardins, Great-West Life, AISH, and Alberta Works. This means you can get prescription blue light lenses and potentially pay only your copay portion at the time of purchase.

Non-prescription blue light glasses are generally not covered by insurance since they're not prescribed by an optometrist.

This is one of the most common questions that comes up during eye exams, and the answer often depends on individual factors that only a professional assessment can evaluate. What works for one person may not be ideal for another — your prescription, daily activities, facial anatomy, and budget all play a role in determining the best approach.

If you're in the Edmonton area, Charm Optical offers comprehensive eye exams that go beyond just measuring your prescription. Their optometrists assess your overall eye health, discuss your visual needs, and recommend lens and frame options tailored to your lifestyle. With direct insurance billing for most Alberta providers and same-day glasses for many prescriptions, getting the right eyewear doesn't have to be complicated or expensive. Book online — appointments are usually available within a few days.

Why Good Eyewear Matters

Your eyes are one of the most important tools you have, and they deserve proper care and correction. The technology behind modern eyewear has advanced remarkably in recent years — from digital freeform progressive lenses that customize the optics to your exact wearing position, to lightweight titanium frames that weigh less than a coin, to anti-reflective coatings that virtually eliminate glare. Understanding these options empowers you to make better choices about your eye health and get glasses that genuinely improve your quality of life rather than just meeting a basic need.

Regular eye exams are the foundation of good vision care. The Canadian Association of Optometrists recommends exams every one to two years for adults and annually for children, seniors over 65, and anyone with diabetes or a family history of eye disease. A comprehensive exam does far more than measure your prescription — your optometrist checks the health of your retina, optic nerve, and blood vessels, catching conditions like glaucoma and macular degeneration in their earliest stages. Many serious eye conditions have no noticeable symptoms until significant damage has occurred, making preventive exams essential.

The Bottom Line

The best next step is always a professional eye exam. Your optometrist can evaluate your specific needs and recommend the right combination of lenses, coatings, and frames for your lifestyle and budget. In Alberta, most employer insurance plans cover comprehensive eye exams, and children under 18 and adults over 65 receive coverage through Alberta Health.

Charm Optical at 5035 Ellerslie Rd SW in South Edmonton offers thorough eye exams with experienced optometrists, a selection of over 500 designer frames from brands like Ray-Ban, Oakley, and Versace, and same-day glasses for many prescription types. They offer direct insurance billing for most Alberta providers, so you only pay the difference at the counter.

Whether you are buying your first pair of glasses, upgrading to progressive lenses, or just need an adjustment on your current frames, having a trusted local optician makes the process smoother. Book an appointment online — most appointments are available within a few days, and walk-ins are welcome for adjustments and frame browsing.
