How to get used to wearing contacts<br>Always consult a licensed eye care professional. Contacts are a medical device and should be treated as such. This is true even if your eyesight is fine and you are only interested in turning your brown eyes into " baby blues " with colored lenses.
Contacts can be worn for reasons other than bad vision.
The passage talked about getting contacts to change your eye color even for people without eyesight problems. Therefore you can get contacts even if you have good vision. My statement is correct.
