Ophthalmologists Reveal 13 Essential Tips for Lifelong Eye Health
Eye health is frequently overlooked until issues arise, but lifestyle factors such as screen time and smoking can significantly impact vision. In this comprehensive guide, NHS ophthalmologists provide expert advice on safeguarding your eyesight through proactive measures and daily habits.
Seek Prompt Professional Help
Dr Dilani Siriwardena, a consultant ophthalmologist at Moorfields Eye Hospital in London, emphasises the sensitivity of the cornea, noting it has more nerve endings per square millimetre than any other body part. "A minor scratch or particle can feel intensely painful," she explains. While serious changes require immediate attention, Siriwardena advises that around 40% of eye casualty visits involve front-of-eye issues manageable with self-care or pharmacy guidance.
Dr Meera Radia of Imperial College Healthcare NHS Trust recommends pharmacies for conjunctivitis, styes, or dry eye, and opticians for vision changes, flashes, or headaches. "Opticians can assess eye pressure, the retina, and optic nerve, acting as a GP for your eyes," says Dr Zaria Ali from Manchester Royal Eye Hospital. For sudden vision loss or severe injuries like lacerations, proceed directly to A&E.
Prioritise Regular Eye Tests
Siriwardena stresses that biannual sight tests are paramount, even for those with good vision. "Opticians can detect silent conditions like glaucoma, the leading cause of irreversible blindness in the UK," she notes. Many are eligible for free tests, and it's vital for meeting driving standards, as Ali points out: "Vision must be better than 6/12." Children should participate in screenings at age four or five to address issues before vision development ceases around age seven.
Embrace Protective Measures
During DIY or construction, industrial-grade safety goggles are essential to prevent injuries from flying debris. Radia reports that eye A&E sees three to five such cases daily. Ali warns that gardening, welding, and snow sports also require protective eyewear to avoid conditions like arc eye from UV exposure.
Wear Sunglasses Year-Round
Radia advises wearing sunglasses with UV400 protection in all seasons to shield against macular degeneration and early cataracts. "Just as we use SPF on skin, eyes need UV protection," she says.
Adopt the 20-20-20 Rule
To combat screen-related eyestrain, Radia recommends the 20-20-20 rule: every 20 minutes, take a 20-second break to look 20 feet away. Ali adds that screens reduce blinking by 50-60%, leading to dryness, so keep eye drops handy and ensure proper screen setup with minimal glare.
Encourage Outdoor Play
With myopia rising in children due to excessive screen use, Radia advocates for two hours of daily outdoor play to support eye development and reduce myopia risk.
Avoid Eye Rubbing
Radia cautions against rubbing eyes, especially in children with allergies, as it can cause keratoconus. Seek anti-allergy drops from a GP or optician instead.
Use Warm Compresses
For eyelid inflammation or blepharitis, Siriwardena suggests warm compresses with a clean flannel to unblock oil glands and prevent tear evaporation.
Quit Smoking
Smoking is a major risk factor for age-related macular degeneration, a leading cause of sight loss, making cessation crucial for eye health.
Maintain a Balanced Diet
A diet rich in leafy greens, fruits, and vegetables supports eye health, with carrots providing beneficial vitamin A. Hydration is key for tear production, as Ali notes: "Drink plenty of water to prevent dry eyes." Those with type 2 diabetes may need more frequent eye tests.
Handle Contact Lenses Responsibly
Siriwardena warns that improper contact lens use is a common cause of eye issues. Limit wear to ten hours, avoid swimming or showering in them, and never sleep with lenses in to reduce infection risks.
Exercise Caution with Eye Makeup
Ali advises checking expiration dates on mascara and eyeliner, discarding after six to twelve months, and removing makeup before bed to prevent swelling or allergies. Fake eyelashes can increase blepharitis risk.
Ensure Adequate Rest
Siriwardena highlights that fatigue can cause dry, sore eyes or twitching. Prioritise sleep and rest your eyes by closing them periodically to alleviate strain.
