Yes, there can be a connection. Dry eye symptoms often feel worse at night or first thing in the morning, and that discomfort can definitely make it harder to fall or stay asleep. On the flip side, poor sleep or conditions like sleep apnea can also worsen dry eye because your eyes don’t get enough moisture or may not close fully while sleeping.
I’ve found using lubricating gel drops before bed, a humidifier in the bedroom, and sometimes a sleep mask really helps ease the pressure and makes it easier to rest. You’re not alone, lots of people with autoimmune conditions and dry eye experience the same cycle.
