What it is, and why it behaves this way
Carbon fibres reinforce a resin matrix: the resin holds the fibres together, while their directions influence how the structure carries loads. A frame may use this composite only in its temples.
Weight in context
Offers lightweight construction potential; resin, joints and material quantity still count.
Flexibility & adjustment
Stiffness depends on the reinforcement and direction. Do not bend composite areas like metal wire.
What to check when trying on
Ask whether the fibre is structural or merely a surface pattern, and which parts can be adjusted.
Care & limitations
Avoid home heating or twisting. Stop using a frame with cracks, layer separation or loose joints until checked.
Put it into practice
Example: a carbon-look print and a load-bearing fibre composite can look similar. Ask what the frame is actually made from.
A common assumption to check
High fibre strength does not prove that assembled glasses are drop-proof or certified sports protection.
