Getting older brings a lot of wisdom, but it also brings some inevitable changes to how we see the world, quite literally. As the structures inside our eyes naturally lose flexibility and degrade over time, our vision shifts. Some of these changes are just mild annoyances, while others can signal more serious conditions that require an eye specialist’s attention.
In this article, we’ll break down some of the most common degenerative eye issues, explain the importance of looking after our eyesight, and share top tips for healthy ageing eyes for retirees.
What Happens to Our Eyesight as We Age?
As with other parts of your body, your eyes undergo changes during the natural process of ageing that affect your eyesight. Many of these changes, including losing the ability to see up close, increased sensitivity to glare, needing brighter light to read, and experiencing dry eyes, are pretty common and easily addressed with glasses, contact lenses, eyedrops, or simple lifestyle adjustments.
However, while the changes above are standard, ageing also increases the risk of developing more serious ocular conditions. Many of these develop silently, without early pain or warning signs.
Cataracts
A cataract occurs when the proteins in your eye’s natural lens break down and clump together, turning a clear lens cloudy. It’s incredibly common; almost everyone develops some degree of cataracts if they live long enough.
Glaucoma
Often called the “silent thief of sight,” glaucoma is a group of eye diseases that damage the optic nerve, usually due to a build-up of fluid pressure inside the eye. It creeps up slowly, destroying your peripheral (side) vision first. Because the brain compensates for the blind spots, you might not notice it until significant damage is done, which makes regular testing vital.
Age-Related Macular Degeneration (AMD)
AMD affects the macula, the tiny, central part of the retina responsible for your sharpest, straight-ahead vision. When cells in the macula deteriorate, it becomes difficult to read, recognise faces, or see fine details, though your side vision usually stays intact.
Diabetic Retinopathy
For those managing diabetes, time increases the likelihood that high blood sugar will damage the tiny, fragile blood vessels inside the retina. This can cause fluid leakage or abnormal blood vessel growth, leading to blurred or fluctuating vision.
Importance of Looking After Our Eyes
The ultimate aim of taking steps to protect your eyesight is to prevent vision loss and, consequently, maintain your independence. Clear vision is the cornerstone of daily autonomy; it dictates our ability to drive safely, manage our own medications, cook, and navigate the world without relying on others. By prioritising regular eye check-ups and protective habits today, you aren’t just saving your sight, you are safeguarding your freedom and quality of life for the future.
Best Eye Health Tips for Retirees
Retirement is your time to take in the view, from travelling to spending time with family. To fully enjoy these years and maintain your independence, protecting your vision is essential. While our eyes naturally change with age, simple habits can keep our sight sharp. Read on to discover exactly how to maintain healthy eyesight as you age.
Attend Regular Eye Exams
While the above may seem scary, according to the Australian Government’s Department of Health Disability and Ageing, approximately 90% of low vision and vision impairment in Australia is treatable if detected early. This underscores the immense importance of attending regular eye exams to prevent vision loss in older adults and to catch conditions before they progress.
If you’re unsure how often you should attend an eye exam, be sure to check with your optometrist or follow guidance from HealthDirect, which recommends an eye test every 2 to 3 years if you’re over the age of 40, or yearly if you’re over the age of 65.
Keep Physically Active
The human body is completely interconnected, and what is good for your heart and metabolism is profoundly good for your vision. Staying physically active acts like a shield for your eyes through several fascinating biological mechanisms.
- Improved Blood Circulation: Aerobic exercise boosts blood flow throughout the body, delivering a rich supply of oxygen and essential nutrients directly to the highly active tissues of your retina.
- Lowered Eye Pressure (IOP): Regular physical activity has been shown in clinical studies to reduce intraocular pressure, the fluid pressure inside the eyes. By keeping this pressure in a safe zone, you directly protect the optic nerve and lower your risk of developing glaucoma.
- Blood Sugar & Weight Management: Exercise helps your body manage blood sugar levels, which prevents damage to the blood vessels in your eyes. This reduces your risk of high blood pressure and type 2 diabetes, the primary triggers for conditions like diabetic retinopathy.
Avoid Smoking
You may not think it, but smoking affects your whole body, including your eyes. According to Quit.org, if you smoke, you are more at risk of developing problems that can lead to vision loss and blindness, compared to people who don’t smoke, because:
- Blood Vessel Damage: Cigarettes flood your bloodstream with thousands of chemicals that damage blood vessels throughout your body, including the delicate ones in your eyes.
- Retina and Macula Harm: These harmful toxins can deteriorate the sensitive retina and macula at the back of the eye, directly threatening your clear vision.
In fact, if you’re a smoker, you’re more likely to develop:
- Age-related macular degeneration (AMD)
- Cataracts
- Infected and inflamed eyes
By avoiding smoking, you’re protecting the delicate structures of your eyes and significantly lowering your risk of these sight-threatening conditions.
Eat A Balanced Diet
Your eyes are complex organs that require a constant supply of nutrients to process light, maintain moisture, and protect themselves from damage. Eating a healthy diet is one of the most effective ways to preserve your eyesight and lower your risk of age-related eye conditions.
Different parts of your eye rely on specific vitamins and minerals to function properly and fight off cellular aging:
- Lutein & Zeaxanthin (Dark Leafy Greens): Filters out harmful blue light and UV rays, significantly lowering the risk of cataracts and macular degeneration.
- Vitamin A (Carrots, Sweet Potatoes): Essential for low-light and night vision. A deficiency can lead to severe dry eyes and night blindness.
- Omega-3 Fatty Acids (Fatty Fish): Supports the structural health of the retina and maintains the oily layer of your tear film, preventing dry eye syndrome.
- Vitamins C & E (Citrus, Nuts): Powerful antioxidants that shield fragile eye cells from environmental damage and pollution.
- Zinc (Seafood, Seeds): Helps transport Vitamin A from the liver to the retina to produce protective pigments.
Good nutrition also protects your sight by preventing chronic, systemic diseases:
- Blood Sugar Control: Diets high in processed sugars cause blood sugar spikes that can damage the microscopic blood vessels in your retina over time, leading to diabetic retinopathy.
- Blood Pressure Management: High blood pressure strains your circulatory system, which can restrict blood flow to the optic nerve or cause tiny hemorrhages in the back of the eye.
Protect Your Eyes From UV Rays
One of the easiest and most important ageing eye care tips we can offer you is to never overlook UV protection. In fact, according to the Cancer Council NSW, protecting your eyes from ultraviolet (UV) rays by wearing protective sunglasses and a sun-smart hat helps significantly reduce your risk of developing:
- Cataracts
- Solar keratopathy
- Cancer of the conjunctiva
- Skin cancer of the eyelids and the surrounding area.
To safeguard your eye health, we recommend that seniors look for the following when selecting sunglasses:
- Ensuring they have a lens category of 2 or above on the tag. This means that they provide good UV protection and absorb at least 95% of UV radiation.
- Sunglasses with category 0 or 1 ratings do not offer effective protection from UV rays.
- Note that darker lenses do not automatically mean more protection.
- Ensuring they are wrap-around, close-fitting, and have large lenses to reduce reflected UV radiation and glare that enter (or leak in) around the edges of normal sunglasses.
Stay Hydrated
Chances are you’ve been told again and again the importance of staying hydrated, for your mood, your brain, your digestion, and your physical well-being. But did you know that eye health is just another reason why staying adequately hydrated is so important, particularly as you age?
- Tear Production & Eye Lubrication: Drinking adequate water supports tear film function, helping combat dry eyes, dry eye disease (DED), and related symptoms such as redness and inflammation.
- Regulating Eye Pressure: The eye relies on a watery fluid called the aqueous humor to maintain healthy pressure. Staying hydrated helps maintain the production and drainage of this fluid, which is crucial for minimising the risk of glaucoma.
- Reducing Strain and Preventing Fatigue: Without enough moisture, the cornea’s smooth surface becomes uneven, scattering incoming light. This triggers temporary blurred vision, light sensitivity, and rapid eye fatigue during activities like reading or watching TV.
- Supporting Cataract Prevention: The eye’s lens is made of water and proteins. Chronic dehydration can cause these proteins to cluster and cloud the lens, a condition known as cataracts.
According to Eat For Health, the average recommended water intake for seniors is 2.1L, making staying hydrated one of the easiest ageing eye care tips you can incorporate into your daily routine to protect your sight.
Practical Strategies for Reducing Eye Fatigue
Screens are a permanent part of our daily lives. While we don’t need to give up our favourite devices, we do need to use them responsibly. Implementing a few smart habits can drastically reduce eye fatigue and protect your long-term vision.
- Take Regular Breaks: When reading, staring at a screen, or doing any activity that causes (or induces) strain, step away. Use the 20-20-20 rule: every 20 minutes, look at something 20 feet away for 20 seconds to reset your eyes.
- Adjust Your Lighting: Avoid using devices in a pitch-black room or under harsh glare. Match your room’s ambient brightness to your screen’s brightness so your pupils don’t have to work in overdrive.
- Use “Night” or “Warm” Modes: Activate the built-in blue light filters on your smartphone, tablet, and e-reader (including Kindles). Shifting the display to warmer amber tones significantly reduces visual fatigue.
- Increase the Text Size: Don’t squint or lean forward. Pump up the font size in your device settings so you can read comfortably from a natural, arm ‘s-length distance.
- Make an Effort to Blink: We blink up to 50% less when looking at screens, which causes dry eyes. Make a conscious effort to blink fully and frequently to keep your eyes naturally lubricated.
- Wear Your Glasses: If you have prescribed reading or computer glasses, use them. Pushing through without them forces your eye muscles to strain unnecessarily just to keep images in focus.
