Most adults need around seven to nine hours of sleep each night for overall and eye health.
Why sleep matters for eyes
During sleep, the eyes rest, repair, and refresh the tear film. Too little sleep can leave eyes red, dry, and more sensitive to strain.
- Short sleep is linked with more digital eye strain symptoms
- Poor rest can worsen twitching, grittiness, and blurred focus
- Sleep helps regulate pressure and blood flow around the eyes
- Conditions like sleep apnoea may affect eye health over time

Healthy routines support better sleep and reduce eye fatigue. Simple habits can make screens and long days easier on your vision.
- Keep a regular bedtime and wake-up schedule where possible
- Avoid screens for at least thirty minutes before bed
- Use preservative-free lubricating drops if eyes feel dry at night
- Discuss heavy snoring or waking unrefreshed with your doctor
