Summary:
- Cataracts occur when the eye’s natural lens becomes cloudy, making vision blurry, hazy, or less sharp over time.
- Adults aged 40 and above should have regular eye exams, since early-stage cataracts often show no obvious symptoms.
- Risk factors beyond age include diabetes, UV exposure, smoking, long-term steroid use, previous eye injury or surgery, family history, and high myopia.
- Warning signs include blurred vision, glare or haloes around lights, faded/yellowish colours, difficulty driving at night, and frequent spectacle prescription changes.
- Screening is a simple, painless eye check that assesses lens clarity and overall eye health.
- Recommended frequency: every 2 years for people in their 40s–50s, annually after 60, and more often for those with diabetes or existing cataracts.
- A cataract diagnosis doesn’t always mean surgery — mild cases may just need updated glasses or monitoring; surgery is considered once cataracts affect daily activities.
As we age, it is common for our eyesight to gradually change, and one of the most common reasons is cataracts. Cataracts develop when the eye’s natural lens becomes cloudy, causing vision to become blurry, hazy, or less sharp over time.
Cataracts are one of the leading causes of vision impairment among older adults in Singapore. While they tend to develop slowly, they can eventually affect everyday activities such as reading, driving, or even recognising faces.
Cataract screening in Singapore: A practical guide for adults over 40
Many eye doctors recommend that adults aged 40 and above go for regular eye examinations, even if their vision seems perfectly fine. That is because cataracts usually develop slowly, and in the early stages, you may not notice any obvious symptoms.
A comprehensive cataract screening can help detect early changes in the eye’s lens before they start affecting your day-to-day life. Identifying cataracts early also gives you the chance to monitor progression and discuss treatment options with your eye specialist when the time is right.
It is also worth noting that cataracts do not develop the same way for everyone. Some people experience gradual changes over many years, while others may notice their vision becoming cloudy or blurry more quickly. Regular screenings help ensure that any changes are picked up early, so you can make informed decisions about your eye health.
Why cataract screening is not just for older adults
While cataracts are often linked to ageing, they do not only affect seniors. In some cases, cataracts can develop earlier due to certain health conditions, lifestyle factors, or previous eye issues.
Some factors that may increase your risk of developing cataracts include:
- Diabetes and other chronic medical conditions
- Prolonged exposure to ultraviolet sunlight
- Smoking
- Long-term use of steroid medications
- Previous eye injuries or surgeries
- Family history of cataracts
- High myopia
Signs you should not ignore
One of the challenges with cataracts is that they usually develop gradually. Many people adjust to subtle changes in their vision without realising that cataracts may be the cause.
Rather than waiting for the vision to become significantly affected, it is prudent to have your eyes checked if you notice any of the following:
- Blurred or cloudy vision
- Increased sensitivity to bright lights
- Difficulty driving at night
- Glare from headlights or sunlight
- Haloes appearing around lights
- Colours appearing faded or yellowish
- Frequent changes in spectacle prescription
- Difficulty reading in dim lighting
- Double vision in one eye
What happens during a cataract screening?
A cataract screening is usually a simple and painless eye check. During the consultation, your eye specialist will assess your vision and examine your eyes for signs of cataracts, as well as other conditions that may be affecting your vision.
The screening typically involves a series of eye examinations that allow the specialist to evaluate the clarity of your lens, check the overall health of your eyes, and determine whether cataracts are present. In some cases, additional tests may be recommended to provide a more detailed assessment or help with future treatment planning.
After the examination, your specialist will discuss the findings with you and advise the next course of action.
How often should you go for screening?
The ideal frequency of cataract screening depends on factors such as age, medical history and existing symptoms. The following are general recommendations:
- Every 2 years for adults in their 40s and 50s without significant eye concerns
- Annually for adults over 60
- More frequent reviews for individuals with diabetes, a family history of eye disease or existing cataracts
- Immediate assessment if new visual symptoms develop
Regular eye examinations allow your eye specialist to track any changes over time and intervene when necessary.
What happens after screening?
A diagnosis of cataracts does not automatically mean surgery is required. In fact, many people live comfortably with early-stage cataracts for years before any treatment becomes necessary.
If cataracts are mild, your eye specialist may recommend the following:
- Get updated prescription glasses
- Improve lighting at home or work
- Schedule regular reviews to monitor progression
Surgery is generally considered when cataracts begin interfering with daily activities such as reading, driving, working or enjoying hobbies.
Modern cataract surgery is one of the most commonly performed and successful procedures worldwide. Your eye specialist will discuss the timing, benefits, risks and available lens options as part of a personalised cataract screening and treatment plan.
