Can cancer cause blurred eyes?

Cancer can cause blurred vision.

If the cancer is in the early stage, the lesion is relatively limited and usually does not affect the eyes, so it does not cause blurred vision symptoms. However, if the cancer is in the late stage, the cancer cells migrate to the central nervous system through blood circulation, which can damage the visual center and cause blurred vision. At the same time, advanced cancer patients are prone to severe anemia, which can also lead to ischemia of the central nervous system, which can reduce the function of visual center cells, leading to vision loss and blurred vision.

For cancer patients, if vision problems occur, they should seek medical examination in time to detect and treat potential eye diseases or cancer metastases early.
