The widespread use of digital devices like smartphones, computers, and televisions has become an essential part of daily life across all age groups. Communication, education, work, and recreation demand their compulsory use. Prolonged screen exposure is linked to a cluster of visual symptoms known as Digital Eye Strain (DES). Let us understand the issues one by one. Light emitted from smartphones Causes constriction of pupil → miosis → leading to convergence → difficulty in reading. Blue spectrum of smartphones decreases melatonin production, a hormone controlling sleep-wake cycles → sleep disturbances → insomnia + mental fatigue → dry eyes + tactile hallucinations. Refractive change → myopia due to exposure to light from smartphones and reduced outdoor activity time. IOP – Smartphone use demands ocular adjustments for near vision → increased demand for accommodation and vergence → increased IOP. IOP rise is faster in eyes with anterior chamber depth less than 2....
