<s>[INST] While reading I sometimes lose track of words and find myself following patterns on the page which form between letters. I find myself somewhere near the bottom of the page but have no memory of reading the text, I can see the letters but not the words and the pattern of space on the page standout clearly. This happens regularly when I read. What causes it? Other times I see red or green lines around the sentences and recognize the letters but not the words. Is this related to the pattern problem? [/INST] Hi there, this could be related to concentration problem. It may be related to a medical problem or a psychiatric issue. You should pay attention to see if any other changes have happened, like tremors, palpitations, etc. You may also pay attention to see what is the pattern of your sleep. Reading problem can also be related to refractory problems in the eye. Sometimes we need an eyeglass, or it could be related to change in the eye pressure. For example some medications change the pressure inside the eyes, like some antidepressants, etc. Let me know more about it. I wish you a good health. </s>
