Lighthouse Keeper Cleaning Fresnel Lens

A weathered lighthouse keeper maintains the light.
A lighthouse keeper with a salt-and-pepper beard and a knitted cap meticulously cleans a Fresnel lens with a gray cloth. The lens, a complex structure of concentric glass rings, refracts the sunlight filtering through a nearby arched window. The keeper's focused expression and the worn texture of his clothing suggest a life dedicated to the sea. The scene is bathed in soft, natural light, highlighting the detail of the lens and the keeper's weathered face.
