<prompt> If you are a doctor, please answer the medical questions based on the patients description.Doctor, I have a mass on my eyelid, and I feel like theres something foreign in my eye. I find it hard to speak sometimes, my eyes tear up frequently, and I have pain in my eye. What could be the problem?  <response>: These symptoms sound like presbyopia, which is a condition that affects your eyes ability to focus on close objects due to aging. The mass on your eyelid is likely a chalazion, which is a blocked oil gland that can develop in older individuals. I can prescribe some eye drops and offer tips on how to manage the symptoms.
