You cannot definitively check for or diagnose cataracts at home, as a proper diagnosis requires a professional eye examination by an optometrist or ophthalmologist. However, you can look for common signs and symptoms that may indicate the presence of cataracts or other eye conditions, which should prompt you to schedule a professional appointment.
Recognizing Potential Cataract Symptoms
According to eye care professionals, the primary way to get an idea if cataracts might be developing is by observing changes in your vision. Look for common cataract signs and symptoms, such as:
- Blurry vision: Your vision might become cloudy, foggy, or less sharp, similar to looking through a dirty window.
- Light sensitivity: Bright lights, especially sunlight or headlights at night, might seem too intense or cause discomfort.
- Fading colours: Colours may appear less vibrant, washed out, or yellowish compared to how you remember them.
- Poor night vision: Seeing clearly in dim light becomes more difficult, making driving or navigating in the evening challenging.
- Halos: You might see rings or halos around lights, which can be particularly noticeable around streetlights or car headlights at night.
These symptoms could indicate an underlying problem and tell you it's time to see your optometrist for a thorough eye exam.
Practical Tips for Noticing Symptoms
While you can't perform a clinical test at home, you can pay attention to how your vision changes over time:
- Compare your vision: Notice if one eye seems significantly different from the other, although cataracts often affect both eyes eventually.
- Observe daily activities: How difficult is it to read small print? Is driving at night becoming harder? Are you struggling to see street signs?
- Check colour perception: Look at familiar objects and compare their colours to how you recall them. Do they seem less bright or have a yellowish tint?
- Note light sensitivity: Do bright lights bother you more than they used to? Do you see halos around lights, especially at night?
Why Professional Evaluation is Crucial
Experiencing one or more of these symptoms does not automatically mean you have cataracts, as they can also be signs of other eye conditions. Only a trained eye care professional can perform the necessary tests, such as:
- Visual acuity test: To measure how well you can see at various distances.
- Slit-lamp examination: To examine the cornea, iris, lens (where cataracts form), and the space between the iris and cornea.
- Retinal exam: To examine the back of the eye, including the retina.
These tests allow the professional to see the lens clearly and determine if a cataract is present, assess its severity, and recommend the appropriate course of action.
Common Signs & Symptoms Table
| Symptom | Description | Potential Impact |
