wowowow SILHY soft lenses generally don't cause neo-vascularization.
Neo-vascularization happens when the eye has low or lack of oxygen for an extended period of time. It could be minimized if the eyes are monitored by the Optometrist frequently.
Changing the dailies may not help the problem. It’s best to see the Optometrist to find out what’s the real cause behind it and change it, or fit new lens if needed be.
The cornea receives the bulk of it’s oxygen from the atmosphere. When the lids are closed during sleep far less Oxygen gets to the eye. A contact lens will deprive the cornea of Oxygen in the open and closed eye state but with the added challenge of the closed eye many problems can results.
The Centers for Disease Control and Prevention (CDC) warns that sleeping with your contacts in makes you six to eight times more likely to suffer from a corneal infection. Infections in the eye can be uncomfortable, and they can also cause permanent vision loss.
