Where does light focus? In front of the retina
Hyperopia – Farsightedness; You can see objects better at a distance
Where does light focus? Behind the retina

11. Conjunctivitis, or “pink eye,” is contagious, therefore, towels and washcloths should not be shared.
A. True
B. False
12. Define conjunctivitis.
Inflammation of the conjunctiva (pink mucous membrane around eyes)
AKA “Pink eye”
Can be Viral or Bacterial

13. What should the nurse use to clean the drainage from the eye of a patient with conjunctivitis?
Baby shampoo/Saline irrigation to clean dried drainage.
