Tears lubricate the eyes and wash away particles and foreign objects. A healthy tear film on the eye is necessary for good vision. Dry eye is a common condition that occurs when the natural tear film that covers the surface of the eye is insufficient. UPMC Eye Center ophthalmologists Andrew Eller, MD, and Leela Raju, MD, explain more about this common condition.
Causes of Dry Eye
There are a number of causes, but some of the most common ones include:
- Previous surgeries, such as laser refractive surgery or retinal detachment
- Wearing contact lenses, especially after many years
- Dry heat in our homes or air conditioning in the summer
- Reading intently or staring at a computer
- Various conditions, such as dementia, Bell’s palsy, Sjogren’s syndrome, rheumatoid arthritis, or hyperthyroidism (Grave’s disease)
