Iíve had night contacts (or ortho-k lenses) since 2005. They correct your vision temporarily and are generally hard lenses. The initial fitting and lenses costs between $1500-$2000. How it works is that they are gas permeable contact lenses that gently reshape the front surface of your eye, the cornea, so that when you wake up the next morning, you have ď20/20Ē vision. Pros include not having to wear contacts or glasses during the day when at school or work, and also maintaining your prescription at what it is to somewhat prevent it from getting worse. Cons include higher risk of infection as you are using the same pair of hard lenses, which may lead to scratches and wear and tear, throughout the year, as well as more expensive treatment. To parents night corrective lenses for kids is highly convincing ó they wear the contacts at night, pop them out in the morning, and have perfect vision for the day. Be sure to ask your optometrist for certain risks and benefits for these night corrective lenses. I actually stopped wearing mine in 2012 and my eyesight has not gotten worse. I have switched over to glasses though for ease of use and not having to fill up on contact solutions.
For day lenses, you have the option to chooses hard or soft lens, as well as dailies or weeklies. Iíve heard from my friends who wear contacts that they get dry eyes but the soft dailies are convenient as you can trash them after use and donít have to worry about potential risk of infection as you can whip up a new pair quickly! The FDA does not approve extended overnight wear. And the more frequently you replace, the more comfortable and healthier your eyes can be!
