Contact lense?

more details +pros and cons
thanks!
I believe you are talking about gentle molding Contact lenses, which your doctor can prescribe you to wear overnight. With these contact lenses, your vision can actually improve while you sleep as you mentioned. For some, improvement can be noticed quickly. One article says improvement can be noticed "overnight". The main problems, as I understand it, are costs (insurance does not pay for these lenses) and adjustment time (it takes a while at first). Costs can be very astronomical especially for those with high Astigmatism. I have high astigmatism and Keratoconus, for example, and my eye doctor told me that the cost for gentle molding lenses would be over $10,000. My insurance would not pay anything toward that either. Please see the included links for more information.
Thanks and I hope this helps
