Depending on the material, that can happen, but they should warranty it. Ask about warranty before you buy them, if you do. Polycarbonate lenses are the most impact resistant lens available and are used a lot in this type of frame. Because they are compression molded the lenses have stress which can develop cracks where the lenses are drilled. Standard plastic lenses can break very easily if you sit on them, etc. Ask if they use Trivex. It is also very impact resistant but is better for drill mounted frames.
