They say the eyes are the windows to the soul, but in the medical world, they are windows to your entire body. When I look through your pupils, I’m not just checking your vision—I’m seeing your retina, your optic nerve, and your blood vessels in real-time.
I’ve often diagnosed patients with diabetes or hypertension before they even felt a single symptom, simply by looking at the back of their eyes. Your eyes are early-warning systems for your heart, your brain, and your overall wellness.
Want to keep those windows crystal clear? Here are my Top 3 Tips for a healthy eye lifestyle.

Nutrition isn't just about your waistline; it’s about your vision. To protect your eyes from diseases like macular degeneration, you need a plate full of color.
Green: Load up on spinach, broccoli, and callaloo.
Orange: Reach for pumpkins, carrots, and pawpaws.
Red & Purple: Snack on berries, apples, and beetroots.
The Goal: High antioxidants. If your plate looks like a rainbow, you’re doing it right.
We are living in a digital world, and our eyes are paying the price. When we stare at screens or books, our blink rate plummets. This leads to dry, itchy, and fatigued eyes—especially in air-conditioned offices.
The Pro Tip: The 20-20-20 Rule
Every 20 minutes, take a 20-second break, and look at something 20 feet away.
Why? Closing your eyes for a few seconds re-lubricates the surface, while looking into the distance allows your internal eye muscles to finally relax.


Not sure if you need an eye exam? Try this simple "roadside" test:
If you are 20 metres away from a car and cannot read the number plate (even with your current glasses), it’s time to book an appointment.
You can’t read a book comfortably for more than 30 minutes.
You have high blood pressure or diabetes.
You use long-term steroids (for asthma or other conditions).
