Well, it's true that wearing glasses cause sinus problems. There are four types of sinus problems: acute sinus, subacute sinus, chronic sinus and recurrent sinusitis. Some of the primary symptoms of sinusitis include:headache, facial tenderness, pressure or pain, and fever, sometimes even casue cough and bad breath. Wearing glasses in a long time may add pressure on muscle and blood vessels around nose and eyes which really lead to itching eyes and sneezing. So if you worry about that, just pay attention to the time you wear glasses. Meanwhile if you already get sinus problems, go to see a doctor and your doctor will review your symptoms and give you a physical examination.
