New Delhi, 20 August 2025: A cataract occurs when the eye’s natural lens becomes cloudy due to protein clumping. This clouding blocks or distorts light, leading to blurred or hazy vision. Although cataracts typically develop with age, younger adults are increasingly experiencing them due to various lifestyle and health factors such as prolonged screen exposure, medical conditions like diabetes, and excessive sun exposure.
8 Early Signs You Shouldn’t Ignore
- Blurry or Cloudy Vision
You may begin to notice that your vision becomes increasingly blurry or foggy. Reading small text, recognizing faces, or watching TV may require extra effort. If updated glasses don’t help, a developing cataract could be the reason. - Difficulty Seeing in Low Light
Tasks like driving at night or walking in dimly lit areas become more difficult. Cataracts reduce contrast sensitivity and affect night vision significantly, making activities in poor lighting much harder. - Increased Light Sensitivity and Glare
Bright lights might seem uncomfortable or cause you to squint. You may also notice exaggerated glare from headlights or sunlight, especially while driving. This happens because light is scattered irregularly by the cloudy lens. - Halos Around Lights
Rings, halos, or starbursts around light sources—particularly at night—are common early cataract signs. These distortions affect visibility and can pose a danger while driving or walking in low-light conditions. - Faded or Yellowed Colors
Colors may lose their vibrancy and begin to appear dull, faded, or yellowish. Everyday visuals like flowers, clothes, or food may not look as colorful. This occurs because the clouded lens filters out certain wavelengths of light. - Frequent Prescription Changes
You might find yourself needing new eyeglasses or contact lenses more often than usual. A sudden or frequent change in your vision prescription could point to cataract development. - Double Vision in One Eye
Cataracts may cause double vision in a single eye, even when the other is closed. This symptom results from light being distorted as it passes through the cloudy part of the lens. - Temporary Improvement in Near Vision
Some individuals experience a phase where their near vision suddenly improves, allowing them to read without glasses. While this might seem beneficial, it usually signals the onset of cataracts and is temporary.
Why Early Detection Matters
- Prevents Vision Loss: When detected early, cataracts can often be managed with lifestyle adjustments, improved lighting, or prescription changes before surgery becomes necessary.
- Improves Surgical Outcomes: Cataract surgery is highly successful when done at the right time. Early detection allows for better planning and improved post-operative vision.
- Enhances Quality of Life: Cataracts can impact daily life—driving, reading, and personal safety. Detecting them early means fewer disruptions and a safer, more independent lifestyle.
Who’s at Risk?
Although commonly associated with aging, cataracts can develop in younger people due to:
- Diabetes and High Blood Sugar
- Family History
- Eye Injuries
- Prolonged Use of Steroids or Certain Medications
- Excessive Exposure to UV Light
- Smoking or Poor Lifestyle Habits
Young adults are sometimes unaware of the risk or dismiss early symptoms, attributing them to fatigue or digital eye strain.
How to Respond to Early Symptoms
- Schedule a Comprehensive Eye Exam
Routine eye exams can detect cataracts in their earliest stages. Eye care professionals use dilation and advanced imaging to assess the clarity of the lens. - Keep a Vision Log
If you notice symptoms like blurring, color fading, or trouble at night, track the frequency and severity to discuss with your doctor. - Adopt Preventive Habits
- Wear sunglasses with UV protection
- Avoid smoking
- Eat a diet rich in antioxidants (green leafy vegetables, nuts, fruits)
- Manage health conditions like diabetes and blood pressure
Cataracts in Younger Adults: A Rising Trend
There is a growing number of young adults being diagnosed with early-onset cataracts. This can be linked to factors like:
- Excessive use of digital screens
- Exposure to environmental pollutants
- Uncontrolled metabolic conditions
- Sedentary lifestyles and poor nutrition
In some cases, congenital cataracts (present at birth) or traumatic cataracts (due to injury) may also emerge in adolescence or early adulthood.
Because younger individuals are less likely to suspect cataracts, the condition may progress unnoticed until it significantly interferes with vision.
Treatment and Long-Term Care
When cataracts start to impact daily life or your vision quality, surgery becomes the most effective solution. The procedure involves removing the clouded lens and replacing it with a clear artificial one (intraocular lens or IOL).
It’s typically done under local anesthesia and is a same-day surgery. Post-surgery, vision often improves dramatically within a few days.
Long-term, individuals who have had cataract surgery should:
- Attend regular follow-ups
- Protect eyes from UV light
- Monitor for secondary cataracts (posterior capsule opacification, which can be treated with laser therapy)
Cataracts can slowly and silently impair your vision, often going unnoticed until the damage is more advanced. That’s why it’s important not to ignore the early signs—like blurry vision, increased light sensitivity, color dullness, and difficulty with night vision. Early detection allows for timely treatment, which can restore your eyesight and quality of life.
Whether you’re over 60 or in your 30s, any noticeable change in how you see the world should prompt a visit to your eye specialist. Cataracts are treatable—and in most cases, vision can be fully restored. Don’t wait until it’s too late.
