Teravusõltust

Teravusõltust, also known as sharpness addiction or visual fatigue, is a phenomenon where individuals develop an excessive reliance on high-contrast or sharpened images. This can lead to a decreased tolerance for natural or less processed visuals, causing discomfort or a perceived lack of detail in ordinary settings. The condition is often associated with prolonged exposure to digitally enhanced media, where images are frequently manipulated to appear sharper than they naturally are.

Over time, the brain can adapt to these artificially heightened levels of detail. When presented with images lacking this extreme sharpness, the user may experience a sensation of blurriness or a lack of clarity, even if the image is objectively well-defined. This can manifest as eye strain, headaches, or a general feeling of dissatisfaction with visual input. It's not a recognized medical diagnosis but rather a descriptive term for a perceptual shift caused by consistent exposure to sharpened imagery.

The prevalence of sharpening algorithms in photography, video editing, and display technologies contributes to the potential for teravusõltust. Users who frequently edit their photos or watch content with aggressive sharpening may find themselves unconsciously seeking out this enhanced visual experience. Reducing exposure to over-sharpened content and consciously appreciating natural image fidelity can help mitigate this perceptual effect.
