Different Types of Contact Lenses

Many people who have vision problems decide to wear contact lenses instead of glasses for one reason or another. Contact lenses are clear, flexible disks that fit over the corneas of your eyes and enable you to correct your vision issues just like wearing glasses. Just as it is wise to consider different factors when selecting a pair of eyeglasses, it’s also important to weigh your options when you choose contacts. Since a contact lens fits directly onto the surface of your eye, comfort and a proper fit are of the utmost importance. And like glasses, there are several different types of contact lenses for you to choose from.

The two basic categories of contact lens are soft and hard. Soft contact lenses conform well to the shape of your eye and will stay in place as you move around. People who are athletes and like to lead an active lifestyle do well with soft contact lenses. With soft contact lenses, you’re able to choose from single use lenses, daily wear lenses or extended wear lenses. Single use contact lenses have one pair on lenses in a package that are designed to be worn for one day only, then discarded. Daily wear lenses may be worn morning until night for several weeks depending on the manufacturer, and extended wear lenses are designed to be worn around the clock.

Hard contact lenses are more rigid in texture, and are usually less comfortable than a soft contact lens at the beginning. As you wear them, hard contact lenses eventually become more comfortable and easy to wear. Hard lenses are easier to take care of and are more durable than their soft counterparts. The breathability factor between the eye and contact lens is greater, which makes the risk of infection less. Most hard contact lenses will last from two to three years.

Some other variations of contact lens include hybrid, bifocal and monovision. Hybrid contact lenses have a gas permeable center, but have a soft ring around the outside of the lens. They are beneficial if you have an irregular corneal curvature. Bifocal contacts have two prescriptions within the one lens for both distance and close up, and monovision contacts will have one lens with have a prescription for reading, while the other will have your distance prescription.

Whichever type of contact lenses you choose in the end, just be sure that they fit your cornea well and that you have clear vision while wearing them. Any extras like bifocals or coloured lenses can be worked out once you find the right contacts. Go to your eye doctor and get a thorough eye exam and fitting, so you can be sure your contact lenses will be a benefit instead of a problem. Take the time to learn proper hygiene methods for your contacts, as infection is a common problem. Remove the lenses before you go to bed each night, use the proper contact lens solution and minimize your exposure to water while you’re wearing them.
