The first thing you ll notice about the Acuvue advance lenses is the addition of Hydroclear, made by Johnson and Johnson. Although other types of Acuvue lenses now offer Hydroclear, the advance lenses were the first. Hydraclear is a break through in contact lens technology, perfect for those who have problems with their lenses drying out. If you are just starting to wear contact lenses, using Acuvue 1 day lenses will be the smartest move you have ever hade. These lenses offer you everything people know and love from the Acuvue brand, along with an experience you will love. If you are ready to take things to the next level and get a pair of contacts that you don t need to clean - 1 day lenses are the perfect pair to start your life of contacts out with. There are different manufacturers that produce different types of bifocal contact lenses, meaning that it may take you a bit of research and experimenting to find which type works the best for you. Some lenses however, are made with a unique design, known as concentric. Similar to concentric circles, there are two adjustments - one in the middle the other around the outside. Your optician will tell you what he recommends, which is normally a few hours during the day then take them out. With each passing day, you can wear them for longer periods until your eyes gradually adjust. Another aspect that will take some getting used to, that you don t face with glasses, is knowing how to handle your contact lenses. When you put your contacts in, you should try and put them in using the same order each and every time. This way, you ll know which contact goes in first and you won t get them mixed up. Before you put them in, you should always inspect them each and every time to make sure they aren t torn or damaged. You ll need to spray your glasses and wipe them off a few times each day. Contacts need to be cleaned as well, before you put them in and soaked in solution when you aren t using them. You may also need to use eye drops as well throughout the day when wearing contacts, especially if your eyes start to dry out.
