Vita-POS Hylo-night
 
Hylo-night (formerly VitA-POS) is a cost effective, preservative-free ointment that is easy to use and ideal for night-time use. Hylo-night, is a light paraffin based ointment which also contains vitamin A, which has been shown to improve symptoms of blurred vision and tear film stability in dry eyes. It has a much softer consistency than some of the older eye ointments, and as such is much easier to apply and more comfortable to use. It is completely preservative-free and remains sterile for up to 3 months from first opening. It provides lubrication to the eye surface for at least 6 hours.
As Hylo-night is ointment based it cannot be used with contact lenses, but it does provide long term relief for contact lens wearers i.e. night time use.
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 in their treatment when applied topically.
