Blurred vision in Winter? Cataracts may be the hidden reason
Winter conditions intensify cataract symptoms, making vision issues more apparent. Early detection and lifestyle adjustments can ease discomfort and delay progression.
Many people associate cataracts with ageing alone, but seasonal changes can significantly influence how cataract symptoms are perceived. Ophthalmologists note that winter often makes existing vision problems more noticeable, prompting patients to seek medical advice during this time of year.
According to Dr. Adrian Braganza, MS, DNB, FICO (UK), Consultant – Cataract, Glaucoma & Refractive Lens Surgery at Narayana Nethralaya, cataract symptoms tend to stand out more in winter due to environmental and lifestyle factors rather than sudden disease progression.
HOW WINTER CONDITIONS AFFECT CATARACT VISION
Winter brings shorter days and reduced natural light, which lowers visual contrast. For people with cataracts, this makes cloudy or blurred vision more apparent. Dim lighting conditions can exaggerate the scattering of light caused by the clouded lens, leading to difficulty seeing clearly.
Indoor environments during winter also play a role. Heated rooms often have low humidity, which can cause eye dryness and irritation. “Dryness and surface discomfort further reduce visual clarity, making cataract-related blur feel worse,” explains Dr. Braganza.
In addition, winter involves more early-evening and night-time activities. Cataracts naturally intensify glare, halos, and poor night vision, making tasks like driving after sunset particularly challenging during the colder months.
EARLY WARNING SIGNS FAMILIES SHOULD WATCH FOR
Winter is often when families begin noticing changes in an older adult’s vision. Common warning signs include increased difficulty seeing at night, heightened glare from headlights, and complaints of foggy or misty vision.
Dr. Braganza advises families to watch for subtle behavioural changes as well. “Needing brighter lights for reading, holding books closer, frequent eye discomfort, or struggling to recognize faces in dim lighting can indicate cataract progression,” he says. When these signs become more pronounced in winter, it is a strong signal to schedule an eye examination.
CATARACTS VS NORMAL AGE-RELATED VISION CHANGES
Distinguishing between normal ageing and early cataracts can be confusing. Age-related vision changes usually develop slowly and often improve with updated glasses or better lighting. Cataracts, however, cause persistent blurring that does not fully resolve with new prescriptions.
Key cataract indicators include increased sensitivity to glare, difficulty driving at night, faded or yellowed colours, and a general dimming of vision. If these symptoms continue despite corrective lenses, it may indicate cataract development rather than routine ageing.
LIFESTYLE MEASURES TO SLOW CATARACT PROGRESSION IN WINTER
While cataracts cannot be reversed without surgery, certain habits can help slow their progression and reduce discomfort, especially during winter. Maintaining adequate indoor humidity and staying well hydrated can ease dryness that worsens visual symptoms.
Wearing UV-protective sunglasses remains important even in winter, as ultraviolet exposure contributes to lens damage year-round. Dr. Braganza also emphasizes the importance of controlling systemic conditions such as diabetes, noting that fluctuating blood sugar levels can accelerate cataract formation.
A balanced diet rich in antioxidants, avoiding smoking, ensuring proper lighting at home, and attending regular eye check-ups all support long-term eye health. These steps help maintain visual comfort through the colder months and delay cataract progression.
WHEN TO SEEK MEDICAL ADVICE
If winter-related vision difficulties begin to interfere with daily activities such as reading, driving, or recognizing faces, it is important not to ignore them. Cataracts develop gradually, but early detection allows timely monitoring and intervention.
Regular eye examinations remain the most effective way to distinguish seasonal discomfort from progressive eye disease. As Dr. Braganza notes, “When vision problems persist beyond environmental adjustments, a comprehensive eye check-up becomes essential.”
