Cataracts are one of the most common visual disorders, especially in people over the age of 60. But how can you tell if you are starting to develop them?
What is a cataract?
A cataract is a gradual clouding of the lens, a natural lens located inside the eye. Over time, this lens loses its transparency, which affects the quality of vision. This is a natural process associated with aging, but other factors such as diabetes, smoking, excessive sun exposure, or prolonged use of certain medications (such as corticosteroids) can accelerate its development.
What are the first signs of a cataract?
1. Blurred or cloudy vision: This is often the first symptom noticed. You may feel like you are looking through a veil or a fogged-up window. Your vision becomes less clear, even with your usual glasses or contact lenses.
2. Increased sensitivity to light: Patients with cataracts often complain of intense glare in bright light, such as sunlight or car headlights at night.
3. Decreased night vision : Cataracts make night vision more difficult. Driving at night can become riskier due to poor contrast perception and glare.
4. Altered colour perception: Colours may appear duller or more yellowish. This may go unnoticed at first, but becomes evident when comparing vision between both eyes or after cataract surgery.
5. Frequent need to change glasses: If you notice that you need to change your prescription regularly without significant improvement, this may be a sign that something else—such as a cataract—is affecting your vision.
What should you do if you notice these signs?
If you have one or more of these symptoms, it is essential to consult an optometrist. Through a comprehensive eye exam, they will be able to assess the health of your eyes and confirm whether or not you have cataracts. The good news? Cataract surgery is a common, safe, and highly effective procedure for restoring clear vision.
Cataracts develop slowly, but their effects on quality of life can be significant. Early detection allows for better management and personalized care. Don't wait until your vision deteriorates: a simple appointment with an optometrist can make all the difference.
