Several habits can negatively impact eye health, including smoking, which increases the risk of cataracts and damages the optic nerve. Poor diet choices that lack essential nutrients can lead to vision problems and age-related conditions like macular degeneration. Inadequate protection from UV rays by not wearing sunglasses can cause immediate and long-term damage to the eyes. Additionally, neglecting regular eye exams and not addressing vision changes promptly can lead to undiagnosed eye conditions and permanent vision loss. Ensuring proper eye care and adopting healthy habits is essential for maintaining good eye health.
