Hylo-Night (formerly known as VitA-POS) is an eye ointment for dry eyes. The eye ointment contains retinol palmitate, liquid paraffin, light liquid paraffin, wool fat and soft white paraffin. Hylo-Night is sterile and preservative-free with Vitamin A supplementation.

Who is it for?

Hypromellose eye drops are the first thing normally recommended due to their more basic formulation. They are primarily used for nighttime relief. However, it can be used throughout the day as well. Hylo-Night's ointment properties are more hydrating than Hypromellose. It relieves symptoms of burning, itching, and dry eyes by forming a comfortable, long-lasting protective film on the eyes.

How does it work?

Historically, Vitamin A has a role in maintaining healthy eyes and reducing the likeliness of blindness. The ointment contains Vitamin A to help improve the tear film and protect the eye's surface. Due to its ointment and viscosity properties, Hylo-Night provides up to 6 hours of lubrication, much longer than regular drops, making it most suitable for nighttime. Also, what is beneficial about this formulation is that it lasts six months once open, while more formulations only last 28 days, so it is excellent for patients who require use less often.

Should anyone not use it?

It is suitable for most people but not suitable for contact lenses; there needs to be a 30 minute gap between applying the ointment and reapplying the contact lenses. It is also important to note if you are already taking high doses of Vitamin A by mouth, you may not require the additional Vitamin A and may increase the risk of taking too much.

How do I apply it?

  • Wash your hands and remove the cap from the tube.
  • Pull the lower lid of your eye downwards to form a pocket.
  • Squeeze the tube gently to release the ointment along the inside of the lower part of the eyelid. Avoid touching the eye with the end of the tube as you do this.
  • Close the eye for about 30 seconds and then blink a few times to spread the ointment around the inside of your eye.
  • Repeat the process in your other eye (if required).
