See the world the way
it was meant to be seen.
Every Maré frame is fitted with premium optical-grade CR39 lenses. Not because it sounds impressive - because you notice the difference every single day.
"Most brands obsess over how their frames look. We obsess over what you look through."
Choosing a pair of sunglasses should feel like an upgrade - not just to your style, but to how you experience the world. At Maré, the lens is not an afterthought. It is the foundation everything else is built on.

Six things you will actually notice.
Not features. Not specifications. These are real differences you will feel the moment you put on a pair of Maré frames.
The world through an optical-grade lens is richer. More contrast, truer tones - the kind of deep blue sky that makes you stop for a second and actually look.
Cheap lenses force your eyes to compensate for optical distortion all day. With Maré, there is nothing to compensate for. Just clarity from the first hour to the last.
CR39 is one of the lightest optical-grade materials available. Lightweight enough to forget you have them on. Substantial enough to feel the quality.
Reduced lens distortion means what you are looking at appears the way it actually is. No warping at the edges. No compromise. Just the world, sharp and clear.
When you look good and see clearly, you move differently. There is a quiet confidence that comes from a pair of frames that actually perform. That is the Maré effect.
From early morning light to long summer afternoons, Maré lenses maintain their visual performance as the light changes. Made for real days, not just photographs.
You will feel the difference.
Eyes that feel tired and strained by 3pm
Colours that look faded, flat, or washed out
Optical distortion you have learned to ignore
Headaches on long days in bright sunlight
A pair that looks good in photos but feels average to wear
Eyes that feel comfortable at the end of a long day
Colours that are vivid, accurate, and alive
Optical clarity with zero distortion
A lens so lightweight you forget it is there
A pair that looks incredible and feels even better
CR39 optical-grade lenses.
A deliberate choice.
There is a version of this business that uses cheaper lens materials and pockets the difference. We chose not to do that. CR39 - the optical-grade polymer used in every Maré frame - is trusted by premium eyewear brands worldwide for one reason: it simply performs better.

Everything you want to know
about sunglass lenses.
Straight answers to the questions we hear most often.
CR39 (Columbia Resin 39) is a premium optical-grade polymer developed in the 1940s and still regarded as one of the best lens materials available for sunglasses. It delivers exceptional optical clarity, minimal distortion, and a lightweight feel that glass cannot match. CR39 is the lens material of choice for premium eyewear brands worldwide.
Yes - CR39 is widely considered the gold standard for everyday sunglass lenses. It offers superior optical clarity compared to standard polycarbonate lenses, producing truer colours, sharper vision, and significantly less eye strain over extended wear. Paired with UV400 protection, CR39 lenses deliver both visual quality and complete eye protection.
CR39 offers higher optical clarity and better colour accuracy than polycarbonate. Polycarbonate is more impact-resistant and marginally thinner, making it the right choice for sports and safety eyewear. For premium everyday sunglasses, CR39 delivers a noticeably superior visual experience - less distortion, truer colours, and a cleaner field of view from edge to edge.
Eye fatigue from sunglasses is almost always caused by optical distortion in low-quality lenses. When a lens is not optically precise, your eyes constantly make micro-adjustments to compensate - leading to strain, headaches, and tiredness by the afternoon. CR39 optical-grade lenses eliminate this distortion, allowing your eyes to relax naturally throughout the day.
The difference is felt, not just seen. Premium CR39 lenses deliver noticeably richer colours, sharper optical clarity, and significantly less eye strain compared to budget alternatives. For anyone wearing sunglasses for extended periods - driving, outdoor activities, or everyday wear - the improvement in visual comfort and quality is real and immediate.
UV400 means the lenses block 100% of ultraviolet light with wavelengths up to 400 nanometres - covering both UVA and UVB rays completely. It is the highest standard of UV protection available in sunglasses. All Maré frames include UV400 protection as standard, protecting your eyes from long-term UV damage in Australian conditions.
Maré Eyewear is designed in Melbourne, Australia, with inspiration drawn from the light and coastlines of southern Italy. Every frame is quality-checked in Melbourne before dispatch. Maré offers free standard shipping across Australia and a 1 year warranty on every pair.
