Protecting your eyes is crucial, as eye health is often taken for granted until issues arise. Lifestyle choices, such as screen time and smoking, can significantly impact your vision. Here, experts share their insights on maintaining healthy eyes, from sight tests to sunglasses. But here's where it gets controversial: while regular eye tests are essential, some argue that the 20-20-20 rule is overrated. So, let's explore the debate and uncover the best practices for eye care.
Seek Help, Fast
The eye is an incredibly sensitive organ. Dr. Dilani Siriwardena, an NHS ophthalmologist, explains, "The front of the eye, especially the cornea, has more nerve endings per square millimeter than any other part of the body. A tiny scratch or piece of grit can feel like a brick."
While minor changes in eye health should be taken seriously, it's important not to rush to the hospital unnecessarily. Dr. Siriwardena advises, "Around 40% of eye casualty attendances are due to minor issues that patients can manage themselves or with advice from a pharmacy or optician. It's about assessing the severity."
Dr. Meera Radia, a consultant ophthalmologist, recommends visiting a pharmacy for guidance on common issues like conjunctivitis, styes, or dry eye. For vision changes, flashes and floaters, or headaches, an optician is usually the best first port of call. They can provide eye drops or refer you to a hospital if needed.
In case of a sudden loss of vision or a serious eye injury, such as a laceration or chemical exposure, go straight to your nearest A&E. Dr. Siriwardena suggests, "If a chemical gets into your eye, use the eye wash in most first-aid kits and then go to the hospital."
Get Regular Eye Tests
Even if you have good vision, regular eye tests are crucial. Dr. Siriwardena emphasizes, "The number one thing to do for eye health is to have a sight test every two years."
Choose a local optician you feel comfortable with, as they can detect changes in your prescription, cataracts, or silent conditions. Don't be put off by the expense. Some people are eligible for free sight tests, and opticians can detect early signs of glaucoma, a leading cause of irreversible blindness in the UK.
Dr. Zaria Ali, an ophthalmologist, notes, "Many people don't realize their vision doesn't meet driving standards. It's essential to go to your optician to ensure your vision is better than 6/12."
Put Safety First
When doing DIY or construction work, always protect your eyes. Dr. Radia shares, "We see at least 100 patients daily in our walk-in service, with three to five being construction workers or DIY enthusiasts."
Industrial-grade safety goggles are essential when working with wood or metal, as metallic foreign bodies are common in the cornea. Even gardening can be hazardous, as Dr. Ali warns, "We've seen people with thorns in their eyes."
Protective eyewear is also crucial when welding or engaging in snow sports. Arc eye, caused by unprotected UV exposure, is a painful condition that can be prevented with the right gear.
Wear Shades
In sunny conditions, wear sunglasses, regardless of the season. Dr. Radia advises, "Just as we protect our skin with SPF, we need UV eye protection."
When buying sunglasses, look for labels like UV400, which indicates both UVA and UVB protection. Exposure to UV rays can cause macular degeneration and early cataract development.
Follow the 20-20-20 Rule
The 20-20-20 rule is often recommended to avoid eye strain from screen time. Dr. Radia clarifies, "Blue light from screens doesn't cause significant eye strain, but excessive screen time does."
To combat this, take a 20-second break every 20 minutes and look 20 feet away. While not a strict 20-minute rule, it's a helpful guideline. Dr. Ali adds, "Blinking decreases by 50-60% when using screens, leading to dry eyes. Keep dry-eye drops nearby to remind yourself to use them."
Go Outside
The rise of myopia or shortsightedness among children is concerning. Dr. Radia explains, "Smartphones, iPads, and streaming have detrimental effects on vision development."
Encourage children to play outside for at least two hours daily, as it benefits their developing eyes and reduces the risk of myopia. Outdoor play is a simple yet effective solution to improve eye health.
Don't Rub Growing Eyes
It's tempting to rub irritated eyes, but it's crucial to avoid it, especially for children and young teenagers. Dr. Radia explains, "Rubbing can lead to keratoconus, where the cornea grows in a conical shape."
Instead, try a warm compress. Warm water and a clean flannel can help milk the oil glands, reducing inflammation and preventing dryness.
Don't Smoke
Smoking is a significant risk factor for age-related macular degeneration, a leading cause of sight loss. Dr. Siriwardena advises, "Not smoking is excellent for your eyes."
Eat Your Greens
A sensible diet, controlled blood pressure, and exercise are beneficial for eye health. While no specific foods are required for eye conditions, leafy greens and polyphenols can be beneficial for age-related macular degeneration.
Dr. Radia recommends a wholesome, vitamin-rich diet with plenty of fruits and vegetables. Carrots, rich in vitamin A, can genuinely improve eye health, but won't help you see in the dark. Type 2 diabetes also affects eyesight, requiring more frequent eye tests.
Stay Hydrated
Dr. Ali suggests staying hydrated to prevent dry eyes. "Drink plenty of water, as it affects tear production. If you don't drink enough, your body prioritizes water for other functions, neglecting your eyes."
Be Sensible About Contact Lenses
Contact lens issues are common reasons for eye casualty visits. Dr. Siriwardena advises, "Don't wear them for too long, don't sleep in them, and change them frequently."
Reassuringly, it's impossible to lose a contact lens in your eye. If it's not there, it's either fallen out or still in your eye. Avoid swimming in contact lenses, and consider using goggles that correct your vision if you love swimming.
Use Eye Makeup with Caution
Big mascara, eyeshadow, or eyeliner users should check the expiration date, typically indicated by a circle with six or 12 months. Discard old makeup and remove it before bed. Avoid using makeup if you experience eye swelling and get an allergy test. Fake eyelashes and extensions can increase the risk of blepharitis, so use them cautiously.
Rest Your Eyes
Tiredness can cause sore and gritty eyes, dry eye, and even twitching. Dr. Siriwardena recommends, "Sleep helps, or try relaxing your eyes by lying down and closing them, even if you don't sleep."
Remember, eye health is a priority, and these tips can help you maintain clear vision and prevent potential issues. Stay informed, stay safe, and don't hesitate to seek professional advice when needed.
