Product Insights
Pierce Aviator Sunglasses by Simons' house brand Le 31, priced at 29 CAD and in stock, deliver 100% UV400 protection via non-polarized contrast lenses that prevent LCD blackout and windshield moiré while sharpening contrast on overcast days. The main tradeoff: non-polarization sacrifices polarized glare reduction but enhances driving clarity, while the ultra-thin metal-and-plastic frame, available in patterned brown or black, offers a contemporary tortoise-shell style but cannot be optician-adjusted, may warp under high heat, and lasts 2–3 years with daily wear. Fit is self-assessed—best for oval, square, and heart-shaped faces, ensuring lenses cover eyebrows and avoid cheekbones.
- Driving clarity
Non-polarized lenses avoid LCD screen blackout and windshield stress patterns while driving.
Why this is supported
Catalog verified that the Pierce's lenses are not polarizing.
not polarized
Are the contrast lenses polarized?. This means they avoid the problems polarized lenses introduce: when
Polarized lenses can also
reveal stress patterns in tempered glass, making sections of the aircraft's windshield appear as a distracting moiré or rainbow pattern.
lensmartonline.comBecause the Pierce lacks a polarizing filter, drivers and device users enjoy clear vision without these issues.
- UV protection
Provides 100% UV protection (UV400) independent of polarization.
Why this is supported
The Pierce provides 100% UV protection because the UV-blocking coating is independent of the lens tint or polarization.
The UV light protection is a clear coat; it's not actually the tint on the glasses
ksat.com. This ensures complete elimination of UV rays:
Ultraviolet (UV) light damages the cornea and the retina. Good sunglasses can eliminate UV rays completely.
science.howstuffworks.comEven with contrast tint and no polarization, UV protection remains at the full 100% level.
- Polarization
Non-polarized lenses avoid LCD blackout and windshield moiré, while blocking 100% UV.
Why this is supported
Because the Pierce's lenses are not polarized, they avoid two common drawbacks:
When you view one polarizing filter through another (your sunglasses), they can cancel each other out, causing the screen to appear black or dangerously dim from certain angles.
lensmartonline.comAnd they prevent the distracting stress patterns on windshields.
Polarized lenses can also reveal stress patterns in tempered glass, making sections of the aircraft’s windshield appear as a distracting moiré or rainbow pattern.

- Contrast
Brown lens tint sharpens contrast on overcast days.
Why this is supported
The brown tint filters blue light. According to lensmartonline.com:
Enhances contrast and depth perception by filtering blue light.
lensmartonline.comThis effect has a historical origin:
These solid color lenses are the foundation of the Ray-Ban legacy, developed in the 1930s for U.S. military pilots.

lensmartonline.com- Fit check
Buyers can check fit by ensuring lenses cover eyebrows and avoid cheekbones; best for oval, square, heart-shaped faces.
Why this is supported
Aviators are intended to fit a specific way:
Aviators should fit snugly so that they cover your eyebrows but are not so big that they hit your cheekbones.
wmpeyewear.comThis test helps buyers confirm the single size works for them. Additionally, face shape influences compatibility:
While aviator sunglasses suit most face shapes, they are particularly well-suited for oval, square, and heart-shaped faces.
lensdirect.comThese guidelines together allow buyers to self-assess fit before purchase.
- Frame care
The metal and plastic frame cannot be custom-fit by an optician and may warp under high heat.
Why this is supported
The Pierce's metal-plastic frame includes plastic components that affect fit maintenance.
Plastic: Minimal flexibility, higher risk of snapping.
modernopticals.comThis limits the ability to adjust the frame beyond tightening micro-screws. Additionally,
Plastic: Can deform in high heat (car dashboards, direct sun).
modernopticals.comProper storage is necessary to avoid warping.
- Durability
Daily-use lifespan of 2–3 years, with warping risk and limited adjustability.

Bought the silver colour for my husband. Nice shape and fit. I took off one star because we were surprised to find the lenses are actually mirrored and that wasn’t mentioned in the product description. They still look great so we’ll be keeping them, but would have preferred if the lenses were gradient like how they appear in the photos.
