Benefits of Crizal Lenses for Computer Users

If you’re a compulsive computer user, you need Crizal lenses for your spectacles. Here’s why.

The Effects of Substantial Computer Usage or Screen Time on Your Eyes

Do you spend a ton of time on the computer (and/or other screens)? Yep, you and 100% of the population. (Did you know that Canadians now report spending an average of six to seven—and even up to 12.5—hours per day on screens for recreation alone? Eeeps!)

And are you finding that your eyes are feeling increasingly strained and/or dry, or your vision is worsening thanks to your computer usage? Yep, you and 71% of Canadians! (And, we might add, nearly all of our Markham, Ontario patients we help here at Unionville Optometry.)

That’s right: a recent survey performed by the Canadian Ophthalmological Society found that “In the past 2 years, 71% of Canadians have experienced one or more of the following symptoms around their eyes or their vision, with screen time being the leading factor to their symptoms:

• Dry, itchy and irritated eyes due to screen time (34%)
• Headaches/eye strain due to screen time (30%)
• Sensitivity to light (29%)
• Blurry vision (27%)
• Excessive tearing or watery eyes (26%)
• Seeing halos around lights (17%)
• Redness or swelling of the eyes (16%)” (Canadian Ophthalmological Society, para. 6)

At risk of stating the obvious, that’s a lot of eye issues to contend with. Eye issues that are uncomfortable at best, dangerous at worst.

But there are ways to make your eyes and your screen coexist more peacefully. Our Unionville Optometrists and Opticians are here to help you do exactly that.

Introducing Crizal Lenses for Computer Users: Clearer, Cleaner, Healthier Vision

Already known and loved by those in the know for their clarity, durability, and advanced protective coatings, understanding the benefits of Crizal lenses, especially for computer users, can help you make informed decisions about your eye health and overall visual comfort. Keep reading to explore:

• How Crizal lenses work
• Why they’re so effective, and
• The wide-ranging advantages they offer to anyone who spends long hours in front of screens.

Crizal Lenses Protect Against Blue-Violet Light

One of the most important benefits of Crizal lenses for computer users is their ability to limit exposure to harmful blue-violet light – a high-energy wavelength emitted by screens, LED lighting, and sunlight. Over time, prolonged exposure to blue-violet light has been linked to premature aging of the eye and potential damage to retinal cells.

Crizal lenses incorporate advanced light-filtering technology designed to selectively block a portion of blue-violet wavelengths while still allowing beneficial light – such as blue-turquoise light, which helps regulate sleep-wake cycles – to pass through.

This balanced approach ensures that your eyes are protected without compromising colour perception or visual accuracy.

Crizal Lenses Reduce Digital Eye Strain

Look, it’s no big surprise that staring at digital screens for long periods places unusual demands on your eyes. You’ve felt the effects yourself, day in and day out. Screen glare, contrast changes, and bright pixels force your eyes to refocus and adapt continuously.

Crizal lenses help ease this strain by reducing one of the most significant contributors to discomfort: glare.

The anti-reflective coatings on Crizal lenses minimize reflections from both the front and back surfaces of your lenses. This means your eyes don’t have to work as hard to see clearly, whether you’re navigating a busy spreadsheet (we see you, Excel!); video conferencing (and note-taking at the same time); or switching between multiple monitors (hello, all you multi-taskers, we’ve got your back, or your eyes at the very least).

With this reduced glare and enhanced clarity, many Crizal lens users report back that they have experienced:

• Less eye fatigue
• Improved focus
• Decreased headaches
• Better productivity throughout the day

(Note: These benefits are especially noticeable during long work sessions or evening screen use.)

Crizal Lenses Offer UV Protection – From All Angles

Most eyeglass lenses protect reasonably well against UV rays that come from the front, but UV rays entering from behind or reflecting off the back of lenses can still reach your eyes – and sometimes at levels as high as 50%.

This is an often-overlooked source of UV exposure.

Standard anti-reflective coatings can actually worsen this problem by reflecting UV light through the back surface of the lens into the eye. Crizal lenses solve this problem by incorporating a specialized coating that eliminates almost all UV reflections from the back of the lens. This provides a more complete barrier against ultraviolet damage, helping protect your eyes not only during outdoor activities but also when working near windows or intense indoor lighting.

Crizal Lenses Help Limit Retinal Cell Death

Another remarkable benefit of Crizal lenses is their ability to help limit retinal cell death, which can be accelerated by exposure to the harmful blue-violet wavelengths we discussed earlier. Studies suggest that Crizal coatings can block about 20% of blue-violet light entering the eye and could reduce retinal cell death by up to 25%.

Crizal lenses are engineered so that any blue-violet light entering from behind the lens is allowed to pass through rather than reflecting into your eyes. This unique design minimizes internal reflections, further reducing retinal stress and offering an added layer of protection for long-term vision health.

This is particularly important for reducing the risk of Age-Related Macular Degeneration (AMD) – a condition that affects the central part of the retina and is one of the leading causes of vision loss as we age.

Crizal Lenses Improve Everyday Durability and Vision Clarity

In addition to digital eye protection and overall eye health, Crizal lenses are well known for their durability and ease of maintenance. Here are just a few of their everyday practical benefits:

Scratch Resistant

Daily wear inevitably leads to accidental bumps, drops, or friction from cleaning. (Show us someone who’s never scratched their glasses doing something silly and we’ll show you a spectacle saint!) Crizal lenses feature a scratch-resistant layer that helps maintain clear vision for longer.

Smudge Resistant

Fingerprints and smudges are frustrating and a curse on vision clarity. Crizal’s smudge-resistant coating makes lenses easier to clean and helps them stay that way throughout the day.

Water Repellent

A hydrophobic coating prevents water droplets from sticking to the lens surface, keeping your vision sharp in rainy conditions, during a sweat sesh, or during humid weather.

Dust Repellent

Anti-static technology repels dust (especially helpful in dry environments or near fans or vents).

Glare Reduction

Reflections from overhead office lighting or bright screens can strain the eyes. Crizal’s glare-reducing properties improve visual comfort and reduce distracting reflections.

Why Computer Users Benefit Most From Crizal Technology

Computer work requires sustained focus, rapid, repeated eye movements, and constant exposure to bright screens. (Urgh… our eyes feel strained just thinking about it!) Over time, these factors contribute to dryness, irritation, and fatigue. To reduce this, Crizal lenses address multiple sources of digital strain simultaneously:

• Reduced glare
• Blue-violet light filtering
• UV protection from all directions
• Enhanced clarity
• Lower risk of long-term retinal stress

Whether you’re working on a computer all day (at top speed!), gaming (at an even faster pace), streaming, or studying (or even pretending to), Crizal lenses can help you maintain healthier, more comfortable vision.

Learn More About Crizal Lenses at Unionville Optometry

There is a lot to love about the digital age – improved communication, a wealth of information (albeit some of it fairly dodgy!) at our fingertips, and entertainment for aeons. (Although plenty of that can be classified as more than dodgy, but we’re not here to judge your favourite Netflix shows, we’ve got our own series skeletons to hide!)

The flip side of this, of course, is many digital-related dilemmas, not least the effect of all that screen time on our eyes. Short of going cold turkey on all screen time, which is highly unrealistic, Crizal lenses are your next best bet for crystal clear eyes for longer.

Take the leap; go Crizal clear today.
