Vision changes refer to alterations in how we see, which can occur due to various factors such as aging, health conditions, or environmental influences. Common changes include blurred vision, difficulty focusing on close or distant objects, and increased sensitivity to light. These changes can affect daily activities like reading or driving. Some common causes of vision changes include cataracts, glaucoma, and macular degeneration. Regular eye exams are essential for detecting these issues early. If you notice significant changes in your vision, it's important to consult an eye care professional for proper evaluation and treatment options.
