Millions of Britons struggling with night vision could be experiencing more than just driving difficulties - their sleep quality may be suffering too, according to eye health experts.
New research has uncovered a troubling connection between night blindness and disrupted circadian rhythms, suggesting that the common condition does more damage than previously thought.
The Night Vision and Sleep Connection
Specialists explain that when our eyes struggle to process light effectively after dark, it sends confusing signals to our brain's internal clock. This disruption to our circadian rhythm can lead to persistent sleep issues that many sufferers don't connect to their vision problems.
Professor Michael Hogg, a leading ophthalmologist, emphasises the seriousness of the condition: "Night blindness shouldn't be dismissed as just an inconvenience. It's often an early warning sign of underlying eye conditions that need medical attention."
Red Flags You Shouldn't Ignore
Healthcare professionals urge people to watch for these warning signs:
- Difficulty adapting to dark environments after being in bright light
- Struggling to recognise faces in dimly lit settings
- Increased anxiety about driving after sunset
- Persistent sleep disturbances and fatigue
- Frequent stumbling or bumping into objects in low light
Common Causes and Solutions
The most frequent culprits behind night vision problems include:
- Cataracts - clouding of the eye's natural lens
- Vitamin A deficiency - crucial for retinal health
- Glaucoma - damage to the optic nerve
- Diabetes-related eye conditions
- Genetic conditions like retinitis pigmentosa
Professor Hogg advises: "Anyone experiencing these symptoms should schedule an appointment with their optician immediately. Early detection can prevent more serious complications and significantly improve both vision and sleep quality."
The NHS recommends regular eye examinations, particularly for those over 40 or with family histories of eye conditions. Many treatments are available, from simple dietary changes to surgical interventions, depending on the underlying cause.
