Eye Care Knowledge Base & Glossary

A normal, healthy lens inside the eye is clear and transparent, allowing light rays to pass through easily. A cataract is a condition where this lens becomes cloudy or opaque.

High-intensity digital displays emit concentrated High-Energy Visible (HEV) blue light that penetrates deep into the eye, causing ciliary muscle strain, rapid tear evaporation, and blurred vision. Effective prevention involves utilizing hardware-level warm filters, maintaining ambient contrast matching, and following strict blinking and hydration protocols.
