What is lens haze and how does it affect the quality of photographs?

Lens haze is a phenomenon where a thin layer of fog or haze forms on the surface of a camera lens. This can happen due to factors like dust, moisture, or oils on the lens. Lens haze can reduce the sharpness and clarity of photographs, causing them to appear blurry or lacking in detail. It can also lead to a loss of contrast and color accuracy in the images. Regular cleaning and maintenance of camera lenses can help prevent lens haze and ensure high-quality photographs.
