Best Non-Polarized Sunglasses for Driving

Why some drivers should avoid polarised lenses

Our sunglasses for driving in Singapore guide recommends polarised as the default for most drivers, with a brief note that it can occasionally clash with LCD dashboard displays. This page is for the specific case where that note applies to you: your dashboard, GPS, or mirror already shows the problem, or you'd rather avoid the risk altogether. If polarised has never caused an issue in your car, there's no need to switch — read this as a troubleshooting and alternative-choice guide, not a reversal of the general recommendation.

Polarised lenses work by filtering horizontal light waves, which is exactly what makes them so effective at cutting glare off wet roads, bonnets, and water. But that same filtering effect can interact badly with certain LCD and LED displays, since many screens emit or reflect light in a way that becomes distorted, dimmed, or shows a rainbow-like pattern through a polarising filter.

In a car, this can affect dashboard instrument clusters, infotainment screens, GPS units, and in some vehicles, anti-glare coatings on the rearview mirror itself. If you've ever put on polarised sunglasses and found your dashboard suddenly hard to read or oddly patterned, this is why. Newer vehicles with heavily digital dashboards are more likely to show this issue than older analogue-dial cars — testing your own car before committing to a pair, as suggested in the callout below, avoids the guesswork.

What you give up without polarisation

The honest trade-off: non-polarized lenses don't selectively cancel reflected glare the way polarised lenses do. Glare off a wet road surface, the bonnet of your own car, or the car in front will come through more strongly. A quality Cat 3 UV400 non-polarized lens still substantially reduces overall brightness and direct sun glare — it just won't clean up reflected glare the way polarisation does. For a full comparison of when each type makes sense, see our polarised vs non-polarised sunglasses guide.

What to look for instead

• Cat 3 UV400: The standard, legal category for daytime driving. Blocks 83-92% of visible light and all UV.
• High contrast lens tint: Amber, copper, or brown tints enhance contrast and depth perception without the display-interference issue of polarisation — useful for spotting brake lights and road markings.
• Anti-reflective coating on the back of the lens: Reduces light bouncing off the inside of the lens into your eye from behind, which is a separate issue from glare in front of you.
• Good optical clarity: Cheap non-polarized lenses can have more distortion at the edges. This matters for driving where peripheral awareness counts.

Best lens colours for driving without polarisation

Amber/copper: Increases contrast against green and blue backgrounds — useful for spotting hazards on roads bordered by greenery, common on Singapore expressways and park connector-adjacent roads.

Grey: Neutral colour perception, reduces brightness evenly without shifting colours — a safe, versatile default for driving.

Brown: Similar contrast-boosting properties to amber with slightly more natural colour rendering. Good all-round choice for driving in variable light.

Who should choose non-polarized for driving

Non-polarized is the more sensible choice if any of the following apply: your car's dashboard or infotainment screen shows distortion through polarised lenses, you frequently glance at a phone mount or GPS device while stopped at lights, or you simply haven't noticed a glare problem that polarisation would meaningfully solve. If you drive frequently near water, wet roads, or with a lot of glare off other vehicles, polarised is still worth the trade-off — see our sunglasses for driving in Singapore guide and our related driving in Singapore conditions guide for the fuller picture.
