Lens Technology (Panel Layout)
Version P3 · Panel-over-lens layout · 23 July 2026
Four lenses. One frame.
Every Aero Sphere frame takes any lens in the ladder. Lite is in the frame as standard. Air, Pro and Max are cut and fitted to your frame to order, which is why they take a few days and why they cannot come back once cut.
The frame decides how it looks and how it fits. The lens decides what you see. This page is about the second part.
The honest starting point
Polycarbonate. Light, tough and genuinely good, and the lens every frame ships with. It is also the lens we tell people to buy first, because a Lite pair can come back inside 14 days if the frame doesn't suit you. Nothing else in the range can.
- Impact resistant, which is why polycarbonate is the material used in safety eyewear
- Hard coat and anti-reflective coating as standard
- Not polarised. That is the one thing the upgrades add that this doesn't have.
- Returnable within 14 days if the fit is wrong
Thinner, lighter, all day
A high-index CR-39 lens. The higher index lets the same lens be made thinner and lighter, which is what you notice at hour ten rather than hour one. Polarised, so glare off water, tarmac and glass simply stops arriving.
- Thinner and lighter than a standard-index lens of the same shape
- Glare removed without dimming the whole scene the way a dark tint does
- Hard coat, anti-reflective and hydrophobic top coat
- Mirror finishes available
Optical clarity first
CR-39 at standard index, and the clearest lens we make. An Abbe value of 59 is about as low-dispersion as an optical polymer gets, which in plain terms means clarity that holds all the way to the edge of the lens instead of fringing at the periphery. Around half the weight of crown glass, with none of the risk.
- The highest optical clarity in the range
- Roughly 50% lighter than crown glass
- High abrasion and scratch resistance
- Hard coat, anti-reflective and hydrophobic top coat
- Mirror finishes available
Armour you can see through
Trivex. The material was developed for fighter jet and helicopter windscreens before anybody thought to put it in front of a face, and it is the only lens in the range that gives you clarity and impact resistance without trading one against the other. If the day involves speed, water, or the possibility of something arriving at your eye uninvited, this is the one.
- Exceptional impact and tensile strength
- The lightest lens in the range on the face
- Originally developed for aerospace windscreens
- Hard coat, anti-reflective and hydrophobic top coat
- Mirror finishes available
Reading the numbers
Refractive index is how strongly the material bends light. The higher the number, the thinner the lens can be for the same job. It is a materials figure, not a quality score.
Abbe value measures dispersion. High Abbe means clean, neutral vision to the edge. Low Abbe means colour fringing at the periphery.
Specific gravity is how heavy the material is for its size. Lower is lighter on your face.
