When I was in high school, I finally was allowed to upgrade my bottle-thick glasses to contact lenses. What a huge difference it was! As time has gone by, I've changed the types of lenses I've used from the basic (traditional) to disposable. With very sensitive eyes, I've had to try different types. About 8 years ago, I landed on the Night and Day style and have stuck with it. While they were created to stay in all night, I typically take them out at bedtime like a normal pair of contacts. With the optometrist's blessing, I wear them longer than the recommended 30 days because I'm only wearing them during the day and they're designed for 24/7 usage.
