A subtle change in your vision can be easy to dismiss. Perhaps you notice reading the small print is a little harder, or streetlights have more glare than they used to. While many of these changes are part of natural ageing, they could also be the early signs of cataracts – a common yet treatable eye condition. The key is knowing the difference, so you can act early and preserve clear, sharp vision.
Understanding the Difference: Ageing Eyes vs Cataracts
Natural Age-Related Vision Changes
As we age, the lens in our eye gradually stiffens, making it harder to focus on near objects – a process known as presbyopia. You may find yourself holding books further away or increasing font sizes on your phone. Contrast sensitivity can also decline, making colours seem less vibrant, especially in dim lighting.
Cataract Development: What’s Going On Inside the Eye
Unlike normal ageing, cataracts occur when the proteins within the eye’s lens clump together, causing clouding that interferes with light entering the retina. Over time, this clouding can spread, blurring vision and affecting daily activities such as driving, reading, or recognising faces. Left untreated, cataracts can significantly reduce vision quality, but with modern cataract surgery, clarity can often be fully restored.
At What Age Do Cataracts Begin to Form?
While cataracts are most commonly diagnosed in those over 60, subtle changes can begin much earlier. In fact, some people in their 40s and 50s may develop cataracts due to lifestyle factors, genetic predisposition, or medical conditions. By age 75, around 50% of adults will have cataracts in at least one eye.
Key Symptoms That Could Signal Cataracts
Blurry Vision and Faded Colours
Cataracts can make vision look as though you’re peering through a foggy window. Colours may appear duller or yellowed, and fine details are harder to distinguish.
Sensitivity to Glare and Halos Around Lights
Bright sunlight, car headlights, or even indoor lighting can cause discomfort. Some patients notice halos around lights, especially at night, a common reason why cataracts can make driving more difficult.
Risk Factors: What’s More Than Just Getting Older?
Oxidative Stress and Protein Clumping in the Lens
Exposure to oxidative stress, the imbalance between free radicals and antioxidants, can accelerate lens protein damage, triggering cataract formation earlier.
Smoking, UV Exposure, Diabetes, & More
Your risk increases if you:
- Smoke or have smoked in the past
- Spend significant time in direct sunlight without UV protection
- Have diabetes or certain metabolic conditions
- Take long-term steroid medications
How Common Are Cataracts with Age?
By age 75, the majority of people will have some degree of cataract development. However, early detection and intervention can ensure it doesn’t compromise your quality of life.
Prevention & Lifestyle Habits to Protect Your Vision
Sunglasses, Diet, and Antioxidants
- Wear sunglasses that block 100% of UVA and UVB rays.
- Include antioxidant-rich foods like spinach, blueberries, and carrots in your diet.
- Stay hydrated to support optimal eye health.
Screen Habits, UV Safety, and Routine Eye Checks
- Limit prolonged screen exposure or take regular eye breaks.
- Use hats and UV-blocking eyewear outdoors.
- Schedule regular eye examinations – even if you have no symptoms.
When to See an Eye Specialist About Cataracts
Frequent Prescription Changes
If your glasses prescription changes more than once a year, it could be a sign that your lens clarity is declining.
Night-time Driving Issues & Glare
Difficulty seeing at night, coupled with glare from headlights, is a strong indicator that a professional assessment is needed.
General Eye Health Screening Recommendations
Regular eye examinations, ideally every 1-2 years for adults over 50, allow for early detection and personalised treatment planning.

FAQs
What is the first sign of cataracts?
Blurry or cloudy vision, often accompanied by faded colours, is typically the earliest sign.
Can cataracts go away naturally?
No, once formed, cataracts cannot reverse naturally, but they can be treated with surgery.
At what age should I start regular cataract checks?
Adults should have eye checks every 2 years from age 40, or sooner if there are risk factors.
Can diet really help prevent cataracts?
While diet can’t guarantee prevention, antioxidant-rich foods can help slow progression.
5. How successful is cataract surgery?
Modern cataract surgery has a success rate of over 95%, often restoring full clarity to vision.
