Few days ago I read an article shared by a friend in FB, it's found that there're 30 over worms grow in a girl's eyes who wear contact lens for a prolong period! :0
I'm a contact lens user for about 9 years, and 2-3 years ago I started to invest in colored lens. For all this while, I'm aware of the pros and cons of contacts, 2 main things I practice the most is to clean the lens properly and never wear contacts to sleep. As contact lens is getting more and more common, I'd like to share some infor with you...
*details taken from CIBA vision*
Contact lenses are subject to a build-up of micro-organisms and deposits. If not removed, these deposits and absorbed materials can build up on the lens surface which over time may result in the reduction of comfort and vision as well as an increased risk of contamination.
Tap water contains chlorine, minerals and metal particles, which can damage both the lenses and the eye. So they should not be used for rinsing or storing lenses.
The Five Most Important Things to Know about Lens Care
1.Cleaning and Disinfection
Cleaning and disinfecting are important to kill micro-organisms responsible for eye infections. Follow the manufacturer's instructions carefully for proper contact lens cleaning and disinfection.
Contact lenses must be stored in a proper lens case and in solutions approved for contact lens storage.
Use drops approved for re-wetting contact lenses as needed to alleviate symptoms of lens dryness. This is not an actual lens care step, but can be used for extra comfort.
4.The Lens Case
Data indicate that lens cases are a significant source of microbial contamination. Proper lens case cleaning and frequent case replacement are essential for minimizing the risk of contamination. Always follow the directions on the packaging insert for detailed instructions on cleaning and storing your lens case. Cases should be replaced at least every three months.
Different lenses are made out of different materials. Because each material performs differently, manufacturers recommend a replacement schedule for each type of lens to allow for optimal performance of the lens. Most lenses worn today are intended to be replaced on a frequent basis. Typical replacement frequencies include one day, 1 to 2 weeks and one month.
