Contact Lenses – What You Need to Know About Contacts

Contact lenses, also known as pure contact lenses, are ultra-thin, flexible lenses placed directly on your eyes. Contact lenses are great ocular prosthetics and instruments used by more than 150 million individuals world-wide, and they are worn as a means to correct vision to one degree or another. If you want to know how to choose a pair of contact lenses, then you should be familiar with the basics of the contact lens itself. Basically, contact lenses are made up of two parts: a housing and a lens. The lens is what actually contacts the eye, while the housing helps maintain the contact (thus the name).

The housing of continuous contact lenses is called a lens case. Some contact lenses actually come in one piece – the whole unit is called an extended wear contact lens. Other types of contact lenses come in segments that fit over the cornea, and some even have a ball-shaped housing that allows the eye to move around but still retain a seal (called an extended wear contact lens). These last longer than soft contact lenses, and can even be worn overnight if prescribed by an optometrist. Soft contact lenses are recommended for overnight wear only, because they allow more oxygen into the eye. These lenses also tend to be less comfortable than extended wear contact lenses, although many people find comfort in them as well.

It’s important to note that there are three different classifications of contact lens design: full experience, premium, and decorative contact lenses. The first type is full experience because it offers all of the benefits of traditional lenses. Most premium and decorative contacts are sold as a special experience with a limited warranty to cover the costs of the initial purchase and replacement of the lens. These are very expensive, but many opticians will order them so that their clients can try the lenses and be assured of the highest level of comfort. The final type of contact lens is referred to as a “crest” or “flawless” contact lens. They have flaws that make them less comfortable than other types of contact lenses, but because they’re much less expensive, most people don’t mind buying these as long as they know they’ll be replaced in a timely manner.

There are four different classes of soft contact lenses. The most comfortable and the most common are called “brazilian” and “floating”. Both of these allow oxygen to reach the eye and are highly popular due to the fact that they cause very little irritation and discomfort. They are also perfect for astigmatism patients and those who have experienced astigmatism in their eye’s cornea.


If you wear regular glasses but want to change your eye color, then you may want to consult your eye care professional to see which contact lens solution will be best for you. Many times a patient will choose a color that matches their wardrobe or likes the way it looks on them. Usually the patient is given a prescription and told to get some practice in before wearing it for the first time so that they feel comfortable and can explain why they feel that they need a certain color. If you wear corrective contact lenses for the first time, then your eye care professional will likely give you some instruction on how to properly insert and remove them, as well as an examination of your eye.

The length of continuous wear contact lenses varies greatly by brand and style. Some are made to be worn continuously for a month while others are only to be worn for two weeks. It all depends on what the patient needs and how often they plan to wear the lenses. Some people who wear continual wear lenses only need to wear their contacts for a week or two at a time, while others who wear contacts continuously need to wear their lenses for six to eight weeks. Regardless of the case, it’s important to keep in mind that your contact lens prescription includes the length of continuous wear time, not just the number of days your contact lenses will be worn.
