Yes. If the glass is intact, a broken lens can still be useful.

Practical options:

• Keep it for spare parts.
• Disassemble it to learn how lenses are built; you might even discover an easy fix.

Creative/photo uses:

• Use it for optical experiments.
• For video or stills, holding the lens in front of another lens can create dreamy, prism-like effects.
• If it’s a relatively fast lens, try shooting through it backwards for unusual close-focus or distorted looks; focus by moving the camera.

Non-photo repurposing ideas:

• Pen or pencil holder
• Small container or plant pot if suitable
• Paperweight or doorstop
• Decorative project such as a retro lamp

Be careful when taking it apart: edges, springs, and glass can be hazardous. Also avoid unsafe ideas like using it to concentrate sunlight, since that can damage property or cause injury. If you don’t want to keep it, someone else may still want it for parts or DIY projects.
