Sudden Vision Loss and Digital Eye Strain: Causes and Complete Prevention Guide
Introduction
In recent years, eye problems have become increasingly common due to the heavy use of smartphones, computers, and prolonged screen exposure in daily life.
Sudden vision changes or eye strain are no longer limited to older adults, but are now frequently seen among young people and even children.

It also focuses on preventing vision problems before they develop.
