- What’s more attractive, wearing glasses or contact lenses?
- Which contact lens is better for astigmatism? J&J or cooper or B&L or Alcon?
- What age can I start wearing contact lenses?
- Is it possible for the contacts to travel from the eye to the nose through the sinuses?
- Can you lose contact lenses in the back of your eyes?
No, same as above, the lining of the eye limits it from happening. It doesn’t travel that far back.
- Is the rx the same for -3.00 or -3.25?
- Is wearing coloured contact lenses as comfortable and reliable as normal contact lenses? What's the difference? Are colored contact lenses safe?
- Does oxygen permeability decrease over time with monthly silicone hydrogel contact lenses? I would like to know if I should change to Dailies as I have some neovascularization.
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.
