The Types Of Contact Lenses

Even though they are great for your eyes, all contact lenses arent equal. Although your doctor will help you select the best pair for your eyes, you should always know a little bit about the contacts that are available to choose from. All contact lenses can be separated depending on their wearing schedule, purpose, material, and over transparency.

Materials
Contacts can be separated or best determined by their material. Contacts are divided into two main groups – soft and rigid (hard). Soft lenses are gas permeable to a certain extent, being further categorized by the amount of water they contain. Soft contacts can have either a low, which is less than 50 percent moisture, or a high moisture content, which is more than 50 percent. Rigid or hard contacts on the other hand, are much harder in material and are considered to be gas permeable.

Wearing schedules
Hard contact lenses can last for months, possibly even years before they need to be replaced. Soft contacts on the other hand, have a schedule for replacement. Some may need to be removed every 2 weeks, monthly, or even daily. The more advanced contact lenses, such as Night and Day contacts, will allow you to wear them all day and all night. 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. All three designs have their distinct purpose, and you should always ask your optician before you rush out and buy one.

Many different purposes
As you may already know, contact lenses serve different purposes as well. They can be optical, therapeutic, cosmetic or decorative. Optical are the most common, as they are for the correction of vision and anomalies you have may have. Therapeutic lenses are normally soft contacts that serve to protect your cornea. They are also used as a reservoir for certain medicines that are used to treat various cornea diseases and malfunctions.

Decorative contact lenses are basically color contacts that produce various effects, such as rainbow colors, cats eyes, and so on. Cosmetic on the other hand, are meant to change the overall appearance of your eyes. Most types of cosmetic contact lenses are designed to enhance your overall eye color.

The type for you
With there being several different types of contacts available on the market, you should consult with your optician to find out which are the best for you. If you dont have astigmatism, you certainly wouldnt want to get toric lenses. If you dont know anything about contact lenses, you may end up doing your eyes more harm than good. Contact lenses are designed to correct your vision and often times protect your eyes, which is why you want to choose them carefully.

If you pick your contact lenses carefully, youll get the best type for your eyes. Your optician will give you his recommendations during your fitting exam, and go over how you should care for your new contacts. This way, even if you are new to the world of contacts, youll know what you should and shouldnt do. With the right type of contacts for your eyes – youll find vision to be a new and exciting world.

Switching To Contact Lenses

Switching from glasses to contact lenses is easier than you may think. Contact lenses are the preferred alternative to vision correction these days, offering you the vision enhancement you need at a price you can afford. There are a lot of things youll to need to know about your contacts, although they are far superior to the traditional correction of glasses.

The first thing youll need to do when getting contact lenses is to visit your optician and be fitted for the lenses. Your optician will give you a prescription for your contacts, examine the health of your eyes, and tell you which type of contacts will work the best for you. He or she can also tell you which contacts are best for your budget as well.

These days, there are several contact lenses to choose from. You have many different manufacturers as well, offering many different types, colors, and styles. Not all are suitable for you though, as no 2 eyes are the same. When you get fitted for your contact lenses, your optician will be able to help you make that decision.

When you first start wearing your contacts, you should never wear them for extended periods of time. Contacts will need some time to adjust to your eyes, and your eyes will need some time to rest. If you wear them too long when you start wearing them, they can harm your eyes. 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 dont face with glasses, is knowing how to handle your contact lenses. Youll need to make sure that your hands are clean before you handle your contacts, to avoid scratching or damaging the lenses. When you take your contacts out or put them in your eyes, youll need to handle them – which requires your hands to be clean.

Something you may experience with your new contacts is dry eyes. Dryness in the eyes when wearing contacts is very common, and should be expected. When wearing glasses, this is one problem you wont have. If your eyes start to dry out when wearing your contacts, you should put a few drops of re-wetting or saline solution in your eyes. These drops will help to moisten your eyes and give you some relief from the irritation that dryness causes.

Although glasses need to be cleaned frequently, contact lenses need to be cleaned and disinfected on a daily basis. Protein will build up on the surface of the contacts, requiring them to be cleaned with a disinfecting or multi-purpose solution. The easiest way to do this is to soak your contacts in the solution when you go to sleep at night. This way, you can wake up in the morning and your contact lenses will be ready to wear.

All in all, contact lenses are preferred over glasses. Youll need to change them out though, normally every couple of weeks. Changing them out with a fresh pair will make your eyes feel refreshed, and keep you from getting infections. Contact lenses are great for virtually anyone, and they can give you a full range of sight. They wont hang off your face like glasses – yet they will give the freedom in knowing that you can do virtually any activity you choose.
