Eye strain
Eye strain, also medically termed as asthenopia (from astheno- 'loss of strength' and -opia 'relating to the eyes'), is a common eye condition characterized by non-specific symptoms such as fatigue, pain in or around the eyes, blurred vision, headache, and occasional double vision. These symptoms tend to arise after long-term use of computers, staring at phone screens, digital devices, reading, or other activities that involve extended visual tasks.
