Sudden Light Sensitivity Should Trigger an Eye Check‑up, Ophthalmologist Advises

Sudden glare, halos around lights or worsening night vision should prompt an eye check‑up, says an ophthalmology expert. Dr Ganesh Pillay, who heads research and academics and acts as regional COO for central India at ASG Hospital Limited, explained that constant exposure to street lamps, billboards, screens and vehicle headlights can strain the eyes. He warned that squinting in bright environments is often dismissed as normal city life, but it may signal a refractive or ocular condition. He listed the warning signs: sudden intolerance to brightness, persistent glare, halos, light sensitivity, blurred vision and poor vision at night. Any of these symptoms merit a professional exam rather than being blamed solely on light pollution. At home, Pillay suggested dimming unnecessary lights after sunset and opting for softer, diffused illumination in living rooms and bedrooms, especially before bedtime. He also advised conscious blinking to keep eyes moist during long screen sessions. The simple 20‑20‑20 rule—look away every 20 minutes at something 20 feet distant for 20 seconds—can reduce dryness and fatigue. During commutes, bright LEDs, headlights and illuminated ads can cause visual fatigue, so limiting exposure where possible helps.

Artificial lighting is a permanent feature of urban life, but excessive glare can lead to eye strain and hide early signs of vision problems. Simple lighting adjustments and regular eye checks can prevent long‑term discomfort.
