Cataract: Why Does It Develop and Who Is Most at Risk?
Cataract is one of the most common causes of vision impairment, particularly among older adults. It occurs when the eye’s natural lens becomes cloudy, gradually affecting the clarity of vision. While cataracts are generally associated with ageing, several other factors can increase the risk of developing them at an earlier age. Understanding the causes, risk factors, symptoms, and available treatment options can help patients seek timely care.
What Is a Cataract?
A cataract develops when proteins and other substances in the eye’s natural lens begin to change, causing the lens to become cloudy instead of remaining clear. As the cataract progresses, light cannot pass through the lens properly, resulting in blurred or hazy vision.
Common symptoms include difficulty seeing at night, sensitivity to bright lights, faded colours, frequent changes in spectacle prescription, and blurred vision that gradually worsens.
Why Does Cataract Develop?
Ageing is the most common cause of cataracts. As we grow older, natural changes in the eye’s lens can gradually lead to clouding. However, cataracts may also develop because of other factors, including:
- Diabetes and uncontrolled blood sugar
- Previous eye injuries or surgery
- Prolonged exposure to ultraviolet (UV) radiation
- Long-term use of certain medications, such as corticosteroids
- Smoking and excessive alcohol consumption
- Certain medical conditions
- Family history of cataracts
- Cataracts present from birth or developing during childhood
Not everyone with these risk factors will develop cataracts, but understanding them can encourage people to undergo regular eye examinations.
Who Is Most at Risk of Cataract?
Older adults are at the highest risk, but cataracts are not exclusively an age-related condition. People with diabetes, those who have experienced eye trauma, individuals with prolonged steroid use, and people with significant UV exposure may develop cataracts earlier.
When Is Cataract Surgery Needed?
In the early stages, cataracts may not significantly affect everyday life, and an ophthalmologist may recommend observation and updated glasses. However, when cloudy vision begins interfering with reading, driving, working, recognising faces, or other daily activities, cataract surgery may be considered.
Modern cataract surgery is a commonly performed procedure in which the cloudy natural lens is removed and replaced with an artificial intraocular lens (IOL). Advances in technology have made cataract treatment more precise and patient-focused.
