We all know that Eyesight is one of our most precious possessions. In fact, our sense of sight is responsible for 80% of what we perceive. So just like our body, our eyes need regular care and as always prevention is better than cure.

The lens and retina are continuously exposed to oxygen and light radiation creating free radicals that damage the retina leading to macula degeneration, and cloud over the lens causing cataract.

Numerous studies have proven that vision can be protected by optimising diet and lifestyle along with thorough examinations. So here are some tips...

Eat Right

Remember that saying ‘Never eat with your eyes’? Well how about Eating for your eyes? An Eye-Healthy diet includes foods rich in Vitamins A, C & E; Anti-Oxidants such as lutein and zeaxanthin; and Bioflavonoids. Many of these nutrients are found in different coloured fruits and veggies including leafy greens. Omega-3 fatty acids are also essential for a healthy macula and tear production.

Eye vitamins have been proven to not only maintain good eye health but also slow down the progression of some eye diseases. They typically contain the above nutrients, and some formulations also include Zinc, Selenium, Resveratrol, Bilberry, Grape seed extract. Astaxanthin is also beneficial in protecting the macula, with vegan options sourced from marine microalgae.

Protect your Eyes

From the harmful effects of UV rays with quality sunglasses. Be careful of counterfeit versions, as the tint without UV protection dilates the pupils allowing more harmful rays in. Accumulation of blue light from screens and LED lights can also cause long term oxidative damage. So if you wear prescription glasses, you could choose to have anti-reflective and blue-protect coatings.

Dry air in the home or work can lead to eye dryness and irritation. Using a humidifier, lid hygiene and non-preserved eye drops can alleviate dry eye syndrome.

Get Fit

Exercise improves blood circulation, leading to increase in oxygen levels to the eyes.

Quit Smoking

Apart from increasing the chances of high blood pressure and diabetes, smoking exposes the eyes to high levels of oxidative stress. This accelerates cataracts and increases the risk of macula degeneration threefold.

Take a Break

From repetitive functions. From starting the day looking at our phone, to working on a computer, then crashing in front of the telly, followed by reading on the kindle before bedtime - the blue screen is ruling our lives.. Staring for long periods of time causes eye strain, headaches and blurred vision. So reduce screen time and follow the 20-20-20 rule. Every 20 minutes, take a 20 second break,and focus on an object 20 feet away.

In addition to correct monitor positioning and lighting, remember to blink regularly to keep the eyes moisturised.

Detect Sooner, Protect More

Other than taking the right precautions, it’s equally important for have an annual eye health exam for early identification of any potential issues. Undiagnosed general health problems such as diabetes, hypertension, heart disease, thyroid disease, tumours, MS and neurological disorders can be detected in an eye exam. Advanced testing such as 3D OCT imaging is helpful inspotting signs earlier than traditional tests. This is a non-invasive test that uses light waves [no radiation] to give cross-sectional pictures of the retinal layers, so works like ultrasound of the eye.

In summary, many eye conditions are silent, so the eyes can look and feel normal for years before impacting vision. Fortunately, many vision impairments are preventable if detected on time through regular eye care and advice.
