Early Signs of Cataracts: When Should You Get an Eye Exam?
Have you noticed that your vision isn't quite as sharp as it used to be?
Recognizing blurry vision, glare, faded colours, and other cataract symptoms
Headlights are unusually bright at night. Colours look less vivid. Reading feels harder, even with your usual glasses. Your vision looks cloudy or hazy, like looking through a dirty window.
These changes are often gradual and easy to blame on aging or a changing glasses prescription. However, they can also be early signs of cataracts.
A cataract develops when the eye’s normally clear natural lens becomes cloudy. As the lens changes, it can affect vision clarity, contrast, colour, and glare. Cataracts often develop slowly and without pain, making regular comprehensive eye exams important.
What Is a Cataract?
The natural lens helps focus light onto the retina. When the lens becomes cloudy, light does not pass through as clearly.
Common cataract symptoms include:
Blurry or cloudy vision
Increased glare or halos around lights
Difficulty seeing at night
Faded or yellowish colours
Reduced contrast
Difficulty reading
Frequent prescription changes
Double vision in some cases
Early changes can be subtle. The everyday tasks require more light or that nighttime driving has become more difficult.
Can You Have Cataracts Without Knowing?
Yes. Early cataracts can cause noticeable symptoms.
This is why an eye exam is about more than checking whether you need stronger glasses. A comprehensive examination allows your optometrist to assess the natural lens and look for other eye conditions that can affect vision. Blurred or hazy vision is not always caused by cataracts. Conditions such as glaucoma, retinal disease, corneal problems, dry eye, and diabetes-related eye disease can also affect vision.
How Are Cataracts Diagnosed?
During a comprehensive eye exam, your optometrist can assess:
Visual Acuity – Measures how clearly you see at different distances.
Refraction – Determines whether a change in your glasses prescription can improve your vision.
Slit-Lamp Examination – Provides a magnified view of the eye and allows your optometrist to examine the natural lens for cataract changes.
Eye Health Assessment – Evaluates the structures of the eye for other conditions that can affect vision.
Dilated Eye Examination – When appropriate, dilation provides a wider view of the internal eye structures, including the retina.
Does a Cataract Always Require Surgery?
No. A cataract diagnosis does not automatically mean immediate surgery.
When a cataract is mild, your optometrist can monitor its progression and address your vision needs with updated prescription, improved lighting, glare reduction, and appropriate UV protection. However, cataract surgery is the definitive treatment for removing a cloudy natural lens.
Surgical referral is generally considered when cataracts begin interfering with daily activities such as:
Driving, especially at night
Reading
Working
Recognizing faces
Enjoying hobbies
Performing everyday tasks safely
The decision is based on how much the cataract affects your vision and quality of life.
What Increases the Risk of Cataracts?
Age is a major risk factor, but cataracts can also be associated with:
Diabetes
Smoking
Previous eye injury
Certain medications, including corticosteroids
Previous eye surgery
Long-term UV exposure
You can support your eye health by wearing appropriate UV-protective sunglasses, protecting your eyes from injury, managing health conditions, avoiding smoking, and maintaining regular eye examinations.
When Should You Book an Eye Exam?
Schedule a comprehensive eye exam if you notice:
Increasingly blurry or cloudy vision
More glare from headlights
Difficulty seeing at night
Faded colours
Frequent prescription changes
Difficulty reading
Vision changes affecting work or hobbies
Do not wait until vision problems significantly interfere with your daily life.
