Lense Movement

• Your eyes are constantly moving and contact lenses need to move with your eyes so you can continually see through your optic zone. Movement of the contact lenses also allows your eyes to get oxygen.
  
  

Benefits of Lense Movement

• Contact lenses provide you with full peripheral vision unlike eyeglasses that give you only a partial view. This is one of the many reasons some people prefer contacts over glasses.
  
  

Problems with Lense Movement

• Contacts lenses can and sometimes do slide off the cornea and get stuck behind your eyelid. This is not dangerous and can be fixed in a variety of methods, including looking in the direction of the lense. Contact your eye doctor if you can not find the lense.
  
  

Excessive Movement

• Contact your eye doctor if you experience excessive movement with your contacts or if they continually get stuck behind your eyelid. Most likely they are not the correct fit, but it may also be due to an infection or eye condition.
