CONTACTS!

Contact Lenses are very useful and often preferred over glasses. I mentioned a few "do's" n "don'ts" in my initial post ... However, since then I've still been approached by people on the topic of sleeping in your contacts, so I felt the need to elaborate on this topic based on my own personal experience.

For starters The Contact Lens is placed on the cornea and may move around slightly but for the most part stays in place if the Base Curve is a good fit for your cornea. Despite popular Belief your contact will NOT get stuck behind your eye and stick to your brain. Its is recommended for Contact lens wearers to change the lenses at least once per month. Protein deposits and bacteria can build up on the contact causing irritation, infection and noticeable blurred vision.

From my experiences as a tech and having encountered hundreds of contact lens wearers, those who are the most successful in maintaing good vision and "allowed" to safely continue to use contacts are those who use them responsibly.

NEVER SLEEP IN CONTACTS!
When the lid is closed for an extended period of time and there is a contact lens in there, oxygen cannot reach the surface of the cornea. Ulcers often develop on the cornea which can lead to larger problems like a potential need for a cornea transplant where a cadaver cornea is sewn on to the surface of the eye.. OR contact lens neo-vascularization where blood vessels grow into the iris. Both results can potentially lead to blindness so don't sleep in them.. its not worth it!
When contacts are left in for a long period of time (a month or longer), the lenses can adhere to the surface of the eye and when they are finally removed, the epithelial layer of the cornea is removed as well... (not a good situation)
Symptoms of irritations caused by misuse of contact lenses include but are not limited to light sensitivity (photophobia), excessive tearing, general irritation.

EXTENDED WEAR CONTACTS
Don't believe the hype! Some contacts do allow more oxygen to flow to the cornea but STILL has the potential to cause complications. Just take them out !
Clean/replace contacts as needed. As mentioned earlier the deposits can cause infections and burry vision. Use rewetting drops and preservative free artificial tears NOT "Vie-ZEEN" to treat dry eyes.
In all, contacts both hard lenses or soft are great ways to improve vision when used responsibly!

p.s. dont sleep in your contacts!!! ;0)
