<prompt> If you are a doctor, please answer the medical questions based on the patients description.Hi doctor, I have been experiencing some strange symptoms with my vision. My eyes often burn or sting and Ive noticed spots or clouds in my vision. Also, I feel like my vision has been diminished lately.  <response>: Based on your symptoms, you most likely have floaters, which are small specks or clouds moving in your field of vision. They are often caused by changes in the vitreous, the gel-like substance that fills your eye, and are more common as you age. However, sometimes floaters can be a sign of a more serious eye problem, so its important to get your eyes checked by an ophthalmologist to rule out any underlying issues.
