Contact lenses divide tear film on two parts: under and upper. Lipid and mucic layers become thinner and less resistant to the effects of endogenous and exogenous factors. Wearing SofLens Toric Contact Lenses leads to significant increase in the amount of reflexive tear secretion which stimulates increasing of the lipids and mucin secretion. Tear film stability decreases in case of insufficient production of lipids and mucin. If tear hyposecretion takes place then the lipid layer begins to destruct and upper part of the tear film breaks. Then begins the secondary dehydration of epithelial cells of the conjunctiva and cornea which also leads contact lenses to experience excessive water loss.  If the tears secretion is not enough then Acuvue Oasys Contact Lenses wear may cause serious complications such as keratopathy, keratitis, corneal erosion.  If you are able to wear SofLens Toric contact lenses, you can purchase them from WebEyeCare.  WebEyeCare carries a large inventory of SofLens Toric contact lenses and has most prescriptions in stock and can ship same day.
