The biggest misconception about sunglasses is that polarization protects your eyes from UV rays. It doesn't.

UV protection and polarization are two completely different lens features. Understanding the difference can help you choose the right sunglasses for your sport, lifestyle, and everyday use.

UV400 Protection Comes First

All Knockaround sunglasses sold in Australia feature UV400 protection, blocking 100% of harmful UVA and UVB rays.

That's what protects your eyes from the sun.

Polarization is a separate lens feature that changes how you see by reducing reflected glare. While polarized lenses can be excellent for activities like boating and fishing, many athletes prefer non-polarized lenses because they provide more natural vision and better environmental awareness.

What Polarization Actually Does

Polarized lenses reduce glare created when sunlight reflects off flat surfaces such as:

• Water
• Roads
• Sand
• Snow
• Vehicle windscreens

This can make bright conditions more comfortable, but it can also alter depth perception, reduce certain visual cues, and affect visibility of digital screens.

Importantly, polarization does not provide UV protection on its own.

UV protection and polarization are completely separate lens features.

Why Athletes Often Choose Non-Polarized Sunglasses

Many cyclists, runners, trail runners, mountain bikers, cricketers, baseball players, pickleball players, and beach volleyball players choose non-polarized sunglasses because they prioritise:

• Natural contrast
• Accurate depth perception
• Better terrain awareness
• Improved object tracking
• Consistent vision in changing light

Cycling

Why non-polarized works better

• Preserves road surface detail such as cracks, gravel, potholes, and oil patches
• Maintains natural depth perception when cornering and descending
• Makes bike computers and phone screens easier to read
• Provides more consistent vision as lighting conditions change

Potential drawbacks of polarized lenses

• Can flatten visual cues on road surfaces
• May reduce visibility of reflective hazards
• Can distort LCD displays

For many cyclists, predictable vision is more valuable than maximum glare reduction.

Mountain Biking

Why non-polarized works better

• Improves visibility of trail texture, rocks, roots, and ruts
• Helps riders react faster on technical terrain
• Maintains natural contrast in forests and changing light
• Makes GPS units and bike computers easier to view

Potential drawbacks of polarized lenses

• Can reduce visibility of wet roots and loose rock
• May affect screen readability
• Can diminish subtle terrain contrast

Mountain bikers depend on fast terrain recognition and accurate depth perception.

Running

Why non-polarized works better

• Provides natural contrast across varied terrain
• Helps identify uneven surfaces, curbs, shadows, and obstacles
• Maintains visual consistency when moving between sun and shade

Potential drawbacks of polarized lenses

• Can reduce visual texture cues
• May create an unnatural visual experience for some runners

Many runners prioritise clarity, depth perception, and terrain awareness over glare elimination.

Trail Running

Why non-polarized works better

• Preserves detail on rocks, roots, mud, and loose gravel
• Enhances depth perception on technical descents
• Improves recognition of changing trail conditions
• Performs consistently through mixed lighting environments

Potential drawbacks of polarized lenses

• May flatten terrain texture
• Can make slippery surfaces harder to identify
• May reduce visual cues used for foot placement

Trail runners rely on terrain awareness and natural contrast to move efficiently and safely.

Cricket

Why non-polarized works better

• Helps track the ball against bright skies
• Maintains natural depth perception while batting and fielding
• Assists with judging swing, seam movement, and trajectory
• Delivers consistent vision in changing conditions

Potential drawbacks of polarized lenses

• Can make the ball more difficult to pick up against certain backgrounds
• May reduce subtle visual cues used to judge pace and movement
• Can affect visibility of scoreboards and displays

Cricket is a game of tracking, timing, and visual accuracy.

Beach Volleyball

Why non-polarized works better

• Makes it easier to follow the ball against bright skies
• Preserves natural depth perception during rallies
• Provides consistent vision while changing direction rapidly
• Helps players judge spin and trajectory

Potential drawbacks of polarized lenses

• Can over-filter reflected light from sand
• May alter depth cues during overhead tracking

Fast reactions and accurate ball tracking are critical on the beach.

Baseball

Why non-polarized works better

• Supports accurate ball tracking
• Preserves natural contrast against sky and field backgrounds
• Helps fielders judge fly balls more effectively
• Maintains realistic depth perception

Potential drawbacks of polarized lenses

• Can make white baseballs harder to distinguish in certain conditions
• May reduce subtle contrast cues related to spin and movement

Baseball players rely heavily on natural visual information to track and judge the ball.

Pickleball

Why non-polarized works better

• Helps players track the ball during fast exchanges
• Maintains natural contrast on indoor and outdoor courts
• Provides accurate depth perception around the net
• Delivers consistent vision in changing light

Potential drawbacks of polarized lenses

• Can slightly alter depth perception during quick volleys
• May reduce visual cues associated with ball movement

Fast visual processing is often more important than glare reduction in pickleball.

The Bottom Line

Polarized lenses are excellent for reducing glare on water, roads, sand, and snow.

However, many athletes prefer non-polarized sunglasses because they preserve the natural visual cues needed for speed, depth perception, terrain awareness, and ball tracking.

Whichever lens you choose, ensure it provides UV400 protection.

That's the feature that protects your eyes.

All Knockaround sunglasses sold in Australia deliver 100% UV400 protection, whether you choose polarized or non-polarized lenses.
