Titanium, metal or plastic glasses frames: which lasts longest?
Titanium glasses frames are the lightest strong option and do not rust, but they cost more. Metal frames, on the other hand, are slim and easy to adjust, while plastic frames (including polymer and TR90) are light, flexible and come in many colours. So the best choice depends on your budget, your skin and how you treat your glasses. Here is how they compare in Nigerian heat and daily use.

Compare titanium glasses frames with metal and plastic
| Material | Weight | Strength | Rust and sweat | Price | Best for |
|---|---|---|---|---|---|
| Titanium | Very light | Very strong | Does not rust | Higher | All-day wear and sensitive skin |

| Plastic, polymer and TR90 | Very light | Flexible and tough | Does not rust | Low to medium | Colour, kids and active use |
Why choose titanium glasses frames?
Light and strong, titanium does not corrode from sweat or humid weather. It is also a common choice for people whose skin reacts to cheaper metals. However, there is a trade-off, because titanium frames usually cost more. So if you wear glasses all day and want a pair that lasts, titanium is the safest choice. Browse our titanium frames.
Metal frames
Metal frames are slim and classic. In addition, an optician can usually adjust the nose pads with ease. On the other hand, cheaper metals can tarnish with sweat and may irritate sensitive skin. For that reason, look for a non tarnish finish.
Plastic, polymer and TR90 frames
Plastic and polymer frames are light, come in many colours and cost less. TR90, for example, is a flexible, tough material that is popular for everyday and active use. Plastic frames do not rust. However, they can warp if you leave them in a hot car or on a dashboard, which matters in Nigerian heat.
Which frame material should you choose?
- All-day wear and the longest life: titanium.
- Hot, humid or sweaty days: titanium, or metal with a non tarnish finish.
- Sensitive skin: titanium.
- Tight budget or bold colours: plastic, polymer or TR90.
- Kids and active use: flexible TR90 or polymer.
How to make any frame last longer
- Put glasses on and take them off with both hands.
- Clean them with lukewarm water and a soft microfibre cloth, not your shirt.
- Keep them in a case, because many of our frames come in a case with a lens cleaner.
- Never leave them in a hot car or on the dashboard.
- Finally, have loose screws and nose pads checked.
Check the fit before you buy
The right material still needs the right size. First, find your face shape. Then check the measurements and who the frame suits in the quick answers on each product page, and try glasses on your face. Also, if you want to avoid fakes, read how to tell if blue light glasses are real.
Frequently asked questions
Is titanium better than metal for glasses frames?
Titanium is lighter, stronger and does not rust or tarnish, so it usually lasts longer. Metal frames, however, cost less and can be a good choice if they have a non tarnish finish.
Are plastic glasses frames durable?
Good plastic, polymer and TR90 frames are tough and flexible, and they do not rust. However, they can warp in strong heat, so do not leave them in a hot car.
Which frame material is best for hot weather?
Titanium, or metal with a non tarnish finish, copes well with sweat and humidity. Whatever the material, keep your glasses out of a hot car.
Can I put prescription lenses in any frame?
No, because not every frame is suitable for prescription lenses. Each product page at Lens & Co says whether a frame suits prescription lenses.
