Adjustable focus lenses

Adjustable focus lenses are optical devices that allow users to change the clarity of what they see by altering the lens's position or shape. This adjustment fine-tunes how light enters your eye or the device, helping you focus on objects at different distances. Common examples include zoom lenses on cameras, optical eyeglasses with adjustable features, or microscopes. These lenses provide flexibility, enabling clearer vision for varied distances without needing multiple fixed-focus lenses, making them versatile tools for improving image quality and visual clarity across different scenarios.
