Is blurred vision due to lung cancer metastasis?

Blurred vision due to lung cancer may be caused by metastasis, refractive error, eye fatigue, etc.

1. Metastasis: Lung cancer is a very common disease that can be transferred to the liver, bones, adrenal glands, and brain through the blood circulation. If a lung cancer patient has brain metastasis, or in the area controlled by the optic nerve or after the tumor expands, it will cause pressure on the optic nerve.

2. Refractive error: Because parallel light passes through the optical system of the eye and cannot be accurately focused on the retina, it causes visual distortion, which leads to blurred vision and blurred vision. The treatment method is to use corrective lenses or refractive surgery to focus parallel light on the retina to achieve the purpose of relieving symptoms.

3. Visual fatigue: Staying up late for a long time or using electronic screens such as computers and mobile phones for a long time will cause eye fatigue, leading to dizziness, dry eyes, blurred vision, etc. Pay attention to the combination of work and rest, minimize the use of computer screens, look at the distance between work and study, and do eye exercises at the same time. Apply eye heat compresses at night to promote blood circulation and reduce eye fatigue.

Blurred eyes due to lung cancer may also be caused by diseases such as glaucoma and cataracts. If the symptoms are not relieved after lifestyle adjustments, you must seek medical attention in time to avoid delaying the disease.
