Cataracts are a common eye condition, especially as we age, but they can affect people of all ages and walks of life. Recognising cataracts’ symptoms is key to maintaining your eye health, protecting your vision, and making informed decisions about treatment if needed. In this guide, we’ll walk you through everything you need to know about cataracts symptoms, how cataracts develop, how they’re diagnosed, and what cataract treatment options are available.
What Are Cataracts?
A cataract refers to the cloudiness of the eye’s lens behind the coloured part of your eye (the iris). When this clear lens becomes cloudy, it can affect the way light rays pass through the eye, leading to blurry vision, vision loss, and other visual changes.
What Do Cataracts Look Like?
However, as cataracts develop, certain changes may be noticeable to you or others. Here are key cataract symptoms to keep in mind:
Blurry Vision And Dimness
One of the most recognised symptoms of cataracts is blurry vision. Things may appear out of focus, and colours might not seem as bright or clear.
Glare And Sensitivity To Light
You might find yourself more sensitive to light or experience significant glare. Bright lights can feel uncomfortable or even painful, especially when driving at night.
Double Vision In One Eye
Some people with cataracts may notice double vision in one eye. This is due to the clouded lens distorting light rays entering the eye.
Fading Or Yellowing Of Colours
The lens can take on a yellowish or brownish tint, causing colours to appear faded or less vibrant.
Changes You Might Notice In The Mirror
In more advanced stages, a cloudy lens may appear greyish or milky behind the pupil. Some people describe the appearance as a faint white or yellowish film over the eye.
This is more common in mature or congenital cataracts and isn’t always obvious in early cataract formation.
How Cataracts Develop Over Time
Cataracts develop slowly. You may not realise there’s a problem at first as your brain adjusts to the changes. Eventually, the visual impairment becomes more noticeable.
Over time, you may find that everyday tasks like reading, driving, recognising faces, or working on the computer become more difficult due to reduced vision clarity.
How Are Cataracts Diagnosed?
An experienced eye doctor will conduct a comprehensive eye exam to detect cataracts and assess your eye health.
Tests may include:
- Slit lamp examination to view the lens under magnification
- Retinal examination after pupil dilation
- Visual acuity test
- Tonometry to check eye pressure
When To See An Ophthalmologist
If you experience developing cataract symptoms such as vision changes, trouble reading, glare, or double vision, consult an eye professional. Early intervention can help maintain a clear vision for longer.
Once cataracts are diagnosed, your eye specialist will determine how advanced the cataract is and whether it’s time to consider cataract treatment.
Not all cataracts require immediate surgery. In the early stages, lifestyle adjustments and visual aids may be enough.
Cataract Treatment: What Are Your Options?
When the symptoms of cataracts begin to affect your usual activities, such as reading, driving, or recognising faces, it might be time to consider cataract treatment.
What Happens During Cataract Surgery
During the procedure, your clouded lens is carefully removed and replaced with a clear lens known as an intraocular lens (IOL). This helps restore clear vision by allowing light to pass through the eye properly again.
The procedure is generally done under local anaesthetic, and most people return home the same day. You may be prescribed eye drops to support healing and prevent infection.
Types Of Intraocular Lenses
There are several types of intraocular lenses, each designed to meet different visual needs. Your eye surgeon will guide you in selecting the most suitable lens according to your lifestyle, vision problems, and any underlying medical conditions.
Single-Vision Lenses
These provide clear focus at one distance, typically for distance vision. Glasses may still be required for near tasks such as reading.
Multifocal Or Extended Depth Of Focus Lenses
Designed to improve vision at multiple distances, these lenses may help reduce your dependence on reading glasses or bifocals.
Toric Lenses
Toric IOLs are designed to correct astigmatism, offering clearer vision for those with uneven curvature in the cornea.
Choosing the right IOL is a personalised decision, and your eye surgeon will work closely with you to select a lens that aligns with your visual needs and preferences.
Do Cataracts Develop In Younger People?
Yes, while most cataracts are associated with ageing, they can also occur in younger people, including children and even infants. These are often referred to as early-onset or congenital cataracts, depending on when they appear.
Although less common, several factors may contribute to the development of cataracts at a younger age, such as:
- Eye injuries, including trauma or complications from previous eye surgery
- Exposure to radiation or ultraviolet light
- Genetic conditions or a family history of cataracts
- Certain medical conditions, like diabetes
- The prolonged use of specific medications, such as corticosteroid medicines
If you’re under 40 and notice changes in your vision, like blurry vision, significant glare, or increased light sensitivity, it’s important to talk to an eye surgeon. Early diagnosis will help you manage symptoms and maintain a clear vision for longer.
Common Eye Problems Linked To Cataracts
While cataracts are a distinct condition, they can sometimes occur alongside other eye problems, particularly as we get older. These may include:
- Glaucoma: A condition that affects the optic nerve and can lead to vision loss
- Macular Degeneration: A gradual breakdown of the central part of the retina responsible for sharp vision
- Diabetic Retinopathy: A complication of diabetes that affects the blood vessels in the retina
Having more than one eye condition can affect how cataract symptoms are managed and may influence the timing or approach to cataract treatment.
That’s why scheduling regular eye exams is so important. It allows your eye doctor to monitor your overall vision health, detect cataracts early, and keep an eye on any other potential issues.
Frequently Asked Questions
Do all cataracts require surgery?
Not always. In the early stages, cataracts can often be managed by wearing sunglasses or updating your visual aids.
Can cataracts return after surgery?
Cataracts themselves don’t return, but a condition called posterior capsule opacification (sometimes called a secondary cataract) can cause similar symptoms. It can usually be treated with a simple laser procedure.
Can I drive with cataracts?
If vision problems caused by cataracts are mild, you may still be able to drive. However, once blurry vision, glare, or dim vision starts to affect safety on the road, it’s time to consult your eye doctor about the next steps.
Conclusion
Cataracts are a natural part of ageing for many people, but that doesn’t mean you have to live with vision problems.
Whether you’re noticing blurry vision or significant glare or simply want to protect your eyes, regular eye examinations are the best way to stay ahead. And if you’re ever unsure, an eye doctor can guide you towards the next best step.
