Are polarised lenses for running must-have tech or an overrated gimmick?

If you’re planning on running in sunny weather, you’ll want a pair of reliable running sunglasses to protect your eyes and keep your vision clear for the route ahead. Sunglasses will block harmful UV rays from causing damage and protect from wind and trail debris. Tinted, mirrored, graduated, photochromatic, and polarised – the world of lenses is a pretty confusing place. 

Essentially, it all boils down to the conditions that you’re running or cycling in, the level of bright light, and style preferences. Read on to find out which lenses are best for running and if polarised sunglasses are worth the hype.   

What are polarised lenses?

Polarised lenses are designed to reduce glare from reflective surfaces, like windows, water, or metal, as well as provide the standard UV protection from the sun’s rays.

Unlike mirrored or tinted sunnies, a polarised lens is not always easy to spot. It’s the tech that works behind the scenes to boost comfort and clarity of vision. You may not even be aware if your current sunglasses are polarised, until you try a pair without glare protection. 

But how does it work? The filter in a polarised lens creates vertical openings for light to fit through, blocking out any horizontal light that reflects off shiny surfaces, causing glare.

Originally developed for water sports and driving, polarized lenses are now being marketed to runners as a way to improve visual clarity and comfort during workouts in bright conditions.

If you’re often working out by the water, snow, or other reflective surfaces, then a polarised lens should prove extremely beneficial. 

Why you should opt for polarised lenses

There are several compelling reasons why runners might choose polarised lenses. Let’s break down the key benefits:

Glare reduction

Polarised lenses are particularly effective at cutting glare from wet roads, puddles, snow, or other reflective surfaces. This makes them ideal for road runners, especially after rain or during bright, midday runs.

Any trail runners who tend to opt for routes alongside bodies of water, like along the seafront, lakes, and rivers, should appreciate the comfort boost offered by a polarised lens. 

Reduced eye strain

Less glare means less squinting. Over time, this can significantly reduce eye fatigue, especially on long runs or back-to-back training days.

In a recent study from Frontiers in Sport, athletes wearing polarised lenses reported less eye strain and better comfort, which could indirectly translate to improved performance (Mercatelli, 2023). 

Better visual contrast

Polarisation can help enhance visual clarity and depth perception. For runners, this means being able to more clearly spot potholes on the road, nasty roots and rocks in the trail, and changes in terrain.

Most quality polarised sunglasses also come with full UVA and UVB protection, helping to shield your eyes from harmful solar radiation, which is an absolute must for long-term eye health.

The Half Jacket 2.0 also prioritizes comfort, with padded Unobtainium® earsocks and nose pads that increase grip with sweat, ensuring a secure, non-slip fit during long runs or intense activity. Lightweight and durable, they strike a balance between versatility, and performance.

The sunglasses also include Bollé’s ‘thermogrip’ technology, comprising rubber grips on the temples, ears, and nose that become more secure when exposed to water or sweat.

The polarising disadvantages you need to know 

Despite their benefits, polarised lenses are not without their downsides and it’s important to be aware of these before choosing your next pair of triathlon sunglasses.

Higher price tag

Due to the added tech involved, polarised sunglasses often cost significantly more than non-polarised options. For some runners, the added cost may not be justified by the benefits, especially if they don’t run frequently in bright conditions.

Screen visibility issues

One common complaint is that polarised lenses can make it difficult to read digital screens. If you rely on a GPS running watch or smartphone while training, you might find the display harder to see. This is part of the reason why pilots are not allowed to wear polarised glasses when flying an aircraft. 

Limited usefulness

Polarised lenses offer little benefit in low-light conditions or shaded environments. If you primarily run early in the morning, late in the evening, or under the cover of forested trails, the advantages may be negligible.

This is why casual runners or those in overcast or moderate climates may find that a basic pair of tinted sunglasses offers sufficient protection and comfort, without the added cost that comes with polarised lenses.

The bottom line

So, are polarised lenses for running overrated or essential? The answer depends on your specific needs and environment (boring, we know).

For runners who frequently deal with harsh sunlight and glare, especially on long road runs, polarised lenses can offer meaningful improvements in comfort and visibility. They may not make you run faster, but they can make your run more comfortable, with less effort from squinting. 

For others running or cycling in less intense lighting conditions, the added cost may not be worth it. In that case, a well-fitting pair of non-polarised sunglasses with UV protection might do the job just fine.
