As far as I know, Sjogren's syndrome is a chronic, systemic autoimmune disease that predominantly affects women and targets the salivary glands. It is one of the most complicated eye disorder. So, people diagnosed with it will not be allowed to wear contact lenses,since this will add to the risk of damaging your eyes to a large extent. It is unsafe for you to do so. I advise you to consult a doctor to ask for help.
No, people with sjogren's wear contact lenses can't wear contact lenses. The symptoms of sjorgren's are dry eyes, dry mouth and dry skin. Sjorgren's can affect your body organs such as skin, lungs, livers, kidneys, muscles, blood, blood vessels, brain and so on. When you get this disease, your eyes will lack enough tears and this will lead to eye irritation and feel as if there are sand or grit in your eyes. When your eyes are very dry, using contact lenses will get the situation worse because contact lenses will make your eyes drier. Maybe wearing contacts will hurt your cornea or do great harm to your eyes.
It is not ok and safe for you who are with the sjogren's to wear the contact lenses. It will make your eyes dry easily. And the dryness may cause the infection for the eyes. If the eye gets the inflammation, your eyes will feel uncomfortable. I suggest people with sjogren's not to wear the contact lenses.
