harmful effects of real image​

A real image in optics is formed when light rays actually converge at a point, usually on a screen (like in a projector, camera, or the human eye). By itself, a real image isn’t harmful, but in some situations, it can have harmful effects, especially when associated with light intensity and optical devices:1. Eye Damage – Looking directly at real images formed by very bright light sources (e.g., the sun through a magnifying glass or telescope) can burn the retina and cause permanent vision damage.2. Fire Hazard – A convex lens or mirror can focus sunlight into a real image at a single point, producing intense heat that can ignite paper, dry leaves, or other flammable materials.3. Glare and Discomfort – Concentrated real images from headlights, projectors, or laser optics can cause temporary blindness, eye strain, or headaches.4. Equipment Damage – Sensitive sensors (like in cameras or telescopes) can be damaged if a strong real image of the sun or other bright objects is focused onto them.In short, the harmful effects of real images mostly come from the concentration of light energy at a point.
