SmarTears® Technology is a patented technology developed by Alcon, the global leader in eye care. It is exclusive to the Dailies Total1® brand of contact lenses.
SmarTears Technology helps address contact lens-related dryness. It releases phosphatidylcholine (PC), an ingredient found in your tears. PC helps stabilize the lipid layer of your eye’s tear film, which reduces water evaporation. Without this layer, the tear film would lose moisture 20 times faster. This layer also provides a smooth optical surface for the cornea (the eye’s clear, dome-shaped front surface).
Simply put, SmarTears Technology helps keep the lenses moist and comfortable throughout the wearing period.
What is contact lens-related dryness?
Contact lenses are generally comfortable to wear. But wearing them for long periods can cause dryness, leading to many problems, including irritation, redness, and itchiness.
Contact lens-related dryness may also be due to lens materials and environmental conditions. For instance, contacts made of material with low oxygen transmissibility (not breathable) will likely put the wearer at risk for contact lens-related dryness.
Lens materials with hydrophilic (water-loving) properties may also absorb tears to compensate for water loss throughout the wearing period and leave the eyes dry. Wearing contact lenses in a hot and dry environment or during the winter may also lead to quicker lens dehydration and contact lens-related dryness.
In some cases, the contact lens wearer may not produce enough tears to keep their eyes moist and lubricated, resulting in discomfort when they wear contact lenses. In such cases, the contact lens wearer’s dry eyes may be due to a preexisting medical condition or acquired through smoking or prolonged usage of digital devices.
