Evaporation, Humidity and Lipid Layer
Unlike other treatments, tranquileyes eye hydrating therapy is non-invasive, preserves natural tears, and promotes eye health. How? In a word, humidity.
- The oily lipid layer on the outside of the tear film acts to preserve natural tears and spread them evenly across the eye, keeping them well-moistened.
- As we age, our bodies produce less oils and therefore the oily lipid layer starts to thin.
- Thinning of the lipid layer makes it harder on the eyes to hold tears and protect from evaporation.
- The evaporation rate of natural tears in a dry eye can be four times as high as a normal eye."(1)
- Evaporation rate of natural tears decreases when relative humidity increases."(2)
- Significant changes occur in tear film lipid layer thickness following alterations in humidity of the periocular environment. Increased humidity results in a thickening of the lipid layer and a concurrent relief of dry eye symptoms both during period of exposures and hours after. "(3)
- If evaporation can be controlled and returned to normal levels in patients with low tear flow, the eye might be able to maintain healthier tear osmolarity despite the low flow
tranquileyes provides immediate and long lasting relief from dry, irritated eyes. It restores moisture by increasing humidity around the eyes which prevents the evaporation of natural tears. The increased humidity also improves eye health by the thickening the lipid layer and restoring the eye’s defense against evaporation.
