The short answer: pick acetate for rich color and a bolder look, metal for the lightest and most understated fit, and wood for one-of-a-kind character. Shape decides how frames flatter your face; material decides how they feel and read.
The material comparison table
| Material | Weight | Durability | Hypoallergenic | Look |
|---|---|---|---|---|
| Acetate | Medium | High — flexes, resists snapping | Yes (plant-based plastic) | Rich color, depth, bold presence |
| Metal (steel/alloy) | Light | Medium — can bend, thin rims dent | Usually; nickel can irritate | Thin, minimal, understated |
| Titanium | Very light | Very high — flexes back, rust-proof | Yes — top choice for sensitive skin | Premium, barely-there |
| Wood | Light | Medium — avoid soaking and heat | Yes (natural material) | Unique grain, warm, one-of-one |
| TR90 (nylon) | Very light | Very high — nearly unbreakable | Yes | Sporty, matte, flexible |
How to choose
- Want color and a statement? Acetate — the tortoise, crystal, and layered tones only acetate does well. Shop acetate frames.
- Want light and low-key? Metal or titanium — thin rims disappear on the face. Shop metal frames.
- Want something no one else has? Wood — no two grains are identical. Shop wooden frames.
- Sensitive skin or a strong prescription? Titanium for skin; acetate to hide thick lens edges.
Care by material, briefly
- Acetate — rinse and microfiber; heat can warp it, so no dashboards in summer.
- Metal — watch the tiny screws; a drop of thread-lock saves loose arms.
- Wood — keep it dry; wipe rather than wash, and never leave it soaking.
From our test bench. Material is where cheap frames betray themselves: acetate that yellows, plating that flakes off metal, wood that cracks at the hinge. We flex, tape-test, and inspect hinges on every model — the ones that fail those tests never reach the site.
FAQ
Which frame material is most durable?
Titanium and TR90 top the list — both flex back into shape and resist snapping. Acetate is the most durable of the classic looks; thin metal rims are the easiest to bend.
Are wooden glasses practical for everyday wear?
Yes, with light care — keep them dry and out of extreme heat. They are light and comfortable; they just do not like being soaked or left in a hot car.
