National Mechanical Dry Eye Day – May 19, 2025

National Mechanical Dry Eye Day is observed each year on May 19 in the United States. This day is observed to raise awareness about this age-related disorder of the eye. It is one of the most prevalent age-related eye disorders and is commonly found in those over 60. The condition is identified by the presence of extra conjunctival folds, which are between the eyeball and the eyelids. The lower eyelid is typically affected by the condition. This disrupts the natural flow of tears and eye drops, weakening the tear film, delaying tear clearance, and causing dry eye.

History of National Mechanical Dry Eye Day

National Mechanical Dry Eye Day was founded by Bio-Tissue in 2020 to raise awareness about mechanical dry eye, one of the most disregarded and often misdiagnosed eye conditions. Mechanical dry eye is an age-related ophthalmology disorder that affects up to 98% of patients 60 years or older.

The organization behind National Mechanical Dry Eye Day, Bio-Tissue, Inc, deals with the clinical application of cryopreserved amniotic membrane-based products to treat eye diseases and disorders. The organization was established in 1997. It is also committed to fulfilling the unmet demand for better surgical and therapeutic alternatives for helping eye care professionals quickly identify eye disorders and their proper treatments. They are also pioneers in the treatment of rare eye disorders such as keratitis, recurrent corneal erosions, conjunctivochalasis, pterygium, and dry eye.

Mechanical dry eye symptoms can include dryness or redness, excessive tears from a blocked tear duct, sensitivity loss, or pain in the eye. Excessive tearing is one of the earliest symptoms of damage. Patients with mechanical dry eyes may find this to be a serious worry, and blinking provides no relief. The Tenon’s capsule, which is part of the lower eyelid, might deteriorate as a result of mechanical dry eye and stop the eye from retaining tears. This indicates that the patient is unable to control his or her crying. This can lead to dry, itchy irritation that is resistant to common treatments including artificial tears, anti-inflammatory medications, and punctal occlusion. Mechanical dry eye is often overlooked and underdiagnosed by ophthalmologists. National Mechanical Dry Eye Day hopes to help more people prepare for the disorder as they advance in age.
