Abstract
Described herein are devices and methods of use thereof for treating dry eye, tired eye, or other forms of ocular discomfort such as from contact lenses. The methods generally include applying spatially and/or temporally patterned stimulation to one or more anatomical structures located in an ocular or nasal region. The electrical stimulation may elicit a reflex that activates the lacrimal gland or may directly activate the lacrimal gland or nerves innervating the lacrimal gland to produce tears. The devices may be implantable or handheld, and may be configured to deliver the spatially and/or temporally patterned stimulation patterns described.
