When to See a Doctor: If symptoms persist or worsen, it's important to consult an eye care professional for a comprehensive eye exam. They can identify underlying issues and provide appropriate recommendations or treatments. General Tips: Take Breaks: Follow the 20-20-20 rule and take regular breaks to rest your eyes.
