The difference between the warm and cold tones of the two eyes is mainly due to the following two reasons: First, due to the different density of the lens of both eyes, as we age, the lens density gradually increases and the color changes from transparent to yellowish brown. The rate of aging in both eyes can be different, so there will be inconsistencies in the warm and cold tones that the two eyes appear to have, with the eye with the higher lens density looking warm in tone. As long as the vision has not declined to the extent that it affects life, no treatment is needed for the time being, and it requires gradual habituation and adaptation. Second, due to central plasmacytoid chorioretinopathy, the macular edema in one eye will cause yellowing and warm tones in the scene.
