Tension headache does not usually lead to vision loss, but it should be taken seriously. The key to the treatment of tension headache is to eliminate one’s own tension, maintain a good state of mind, and reasonably arrange work and rest time; if you need medication, you can generally choose analgesics such as Benadryl according to the severity of the condition; antidepressants and anxiety agents such as amitriptyline can help improve the symptoms.
