Keep seeing clearly with weekly lenses! After using these lenses every day for 1-2 weeks you simply throw them away and replace them with a fresh new pair. Through regular replacement youminimize the risk of coatings forming on the lenses and them irritating the eyes. Weekly lenses are available in both traditional hydrogel that you take out every evening and silicon hydrogel that you can wear day and night. Choose the type that suits you!
Who can use them?
Weekly disposables are the most commonly worn contact lens. They replace glasses that hide your face and allow you to vary your style. Be able to show off your stylish eye makeup and be free to choose from all the cool sunglasses available without prescription. With weekly lenses you havetotal freedom of movement. Play a game of football and have full visibility of the other team’s goal or go for a jog without your glasses fogging up or slipping down.
How to clean your weekly lenses
Cleaning your weekly disposable lenses every day will remove at least 90% of all bacteria.
All you need to do is:
1) Wash and dry your hands thoroughly.
2) Rub both sides of the lens against the palm of your hand with your little finger and a few drops of lens solution.
3) Rinse the lens with the lens solution and put it in the case.
4) Fill your lens case with solution and put on the lids. Always read the instructions that come with your lens solution.
Perfect vision all day with extended wear monthly lenses
Do you travel a lot, have a job with long shifts or are you just tired of not being able to see when you wake up in the morning? Maybe you would rather spend the time needed to clean, put in and take out your lenses going able your daily life?
Whatever the reason, extended wear weekly lenses made of silicon hydrogel are the perfect option for you. Thanks to this revolutionary material your lenses now allow up to six times more oxygen to your eye than traditional lenses, you can even sleep with them in! You no longer need to be a slave to your lenses and take them out and clean them every day. You can go to a party knowing your lenses can stay in as long as you can stay out.

The history behind weekly disposable lenses
In the early 1500’s Leonardo da Vinci started sketching ideas for contact lenses but they did not become a reality until the late 1800’s. Monthly lenses can be attributed to a German glassblower called F. A. Müller, who made an ocular prosthesis made of glass to act as protection for a patient who had reduced blink function. In 1949 came the so-called corneal lenses, these were small and only covered the cornea instead of the entire eye. They were made from hard plastic called PMMA. They were relatively expensive, fragile and did not offer much comfort. PMMA lens' greatest problems was that they did not allow oxygen to the eye.
Lack of oxygen in the eye can lead to serious infections and impaired visibility. In 1963 the first soft hydrogel lens, developed by Czech chemist Otto Wichterle, was launched. The development of materials for monthly lenses has progressed and although hydrogel lenses were not as strong and reliable as the lenses today it is still the most common material used. Lenses made from the material Silicon Hydrogel became available in 1999. They allowed so much oxygen into the eye that wearers can sleep with the lenses in and these go by the name Extended Wear Lenses.
