Hydramed Night Sensitive is a lanoline free lubricating ointment ideal for use at night to help relieve the symptoms of dry eyes. Hydramed Night Sensitive combines liquid paraffin, white soft paraffin with vitamin A and EXCLUDING lanolin for enhanced comfort and the thicker nature of the product means that it can often protect the eye throughout the whole night. Vitamin A is part of the natural tear film and as such is very well tolerated as a lubricant. Vitamin A is required for the normal growth, maintenance and maturation of corneal cells and is therefore effective as a treatment when applied topically.
