9 Habits That Can Lead to Worsening Vision

Maintaining good vision is a lifelong commitment, and Vietnamese ophthalmologists are highlighting nine common habits that can significantly harm eyesight over time. The emphasis is firmly on prevention, as modern medicine, while capable of interventions like medication and surgery, cannot fully reverse damage once it occurs. This proactive approach is crucial, especially as age-related vision issues and conditions like myopia, corneal damage, and retinal diseases become increasingly prevalent.

The list of detrimental habits is extensive and often overlooked in daily routines. Sleeping with contact lenses, for instance, creates a breeding ground for bacteria, potentially leading to severe infections and vision loss unless specific long-wear lenses are used. Similarly, the constant gaze at screens without adequate breaks contributes to eye strain and increases the risk of myopia, particularly among younger populations. The recommended "20-20-20" rule—looking at something 20 feet away for 20 seconds every 20 minutes—is a simple yet effective measure to mitigate this strain.

Furthermore, the article stresses the importance of regular eye examinations. Many eye diseases develop silently, without noticeable symptoms, making routine check-ups essential for early detection of conditions like diabetic retinopathy, cataracts, or glaucoma. Ignoring warning signs such as flashes of light, an increase in floaters, or a curtain-like sensation over vision can lead to irreversible vision loss, particularly in cases of retinal tears or detachment.

From a Vietnamese cultural perspective, health is often viewed holistically, and the advice to avoid smoking, maintain a balanced diet, and practice good hygiene (like removing eye makeup) aligns with traditional values of self-care. The specific warning against using tap water to clean contact lenses is particularly relevant in regions where water quality can be a concern, underscoring the need for specialized solutions. The overarching message is clear: protecting one's vision requires conscious effort and adherence to best practices, ensuring that sight is preserved for years to come.
