Just like other contacts however, you will still need to clean them on a regular basis to ensure that the protein is removed. Contact lens designs The designs for contacts are divided into three areas - toric, spherical, and multi-focal. Toric lenses are for those who have astigmatism, spherical is for short sightedness, and the correction of long sightedness, and multi-focal contact lenses are used in the correction of presbyopia. 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. This technology is considered to be among the best - and ideal for anyone who wants the best for their eyes. If you are just starting to wear hard contact lenses or have thought about them in the past, you ll need a 2 - 4 week break period, where you will gradually wear the contacts longer and longer with each passing day. Soft contacts on the other hand, will take less time to get used to, as most people who wear them can break them in a few days. Even though other contacts are great to wear and may feel comfortable, they don t quite match up to everything that Acuvue offers you. For most contact lens users, Acuvue 1 day are the best that money can buy. They aren t that expensive either - especially if you buy them in bulk. If you are just starting to wear contact lenses, using Acuvue 1 day lenses will be the smartest move you have ever hade. There are several manufacturers out there who offer these types of contact lenses, some offering better deals than others. On the Internet you can find a lot of deals from many different manufacturers, many of which won t set you back a lot in terms of money. You can also find extended wear contact lenses locally, although the Internet is the best way to save money. Gas Permeable Contact Lenses Also known as oxygen permeable contacts, gas permeable contact lenses are a lot easier to take care of then other types of contacts - including soft contact lenses. GP (Gas Permeable) contacts are made from a combination of fluorine and silicone, meaning that they won t attract protein near as much as other types of contacts.
