Even though they are great for your eyes, all contact lenses aren’t 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, cat’s 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 don’t have astigmatism, you certainly wouldn’t want to get toric lenses. If you don’t 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, you’ll 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, you’ll know what you should and shouldn’t do. With the right type of contacts for your eyes – you’ll find vision to be a new and exciting world.
As most of us know, contact lenses are the best alternative to glasses. They are small, plastic shaped discs that are made to correct eyesight problems like nearsightedness, astigmatism, farsightedness, and other problems. Contact lenses are also used by those who have had cataract surgery, as they can help the eyes to heal a bit faster.
Contacts are used in the eye, where they will float above a sea of tears that rest in front of the cornea. You should always go to a doctor to be fitted, as the proper fitting and design is very important for safety, comfort, and the accurate vision. If you don’t get fitted for your contacts, you could very well get a pair of contacts that could damage your eyes.
There are several types of contact lenses available in two main types – hard contact lenses and soft contact lenses. The hard contact lenses include gas permeable and the conventional hard lenses. Soft contact lenses include daily wear, extended wear, and disposable wear. These are all great contacts, although you should check with your optician to see what he recommends.
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.
Contact lenses, as we all know, have many different uses. They are mainly used to correct vision, although they can also be used for those who have just had cataracts, especially if the natural lens around was removed. Contacts can also be used in the treatment of various eye diseases, and scars on the cornea that have been caused by infections or injury.
Contact lenses are a great choice for those who have active lifestyles, such as athletes. They won’t fall off like glasses when you run, nor do they hang off your face or fog up. They also offer you a full field of vision as well, which is great for sports. The lens and focus is the same as glass, meaning that you will get the same vision from contacts as you would with a pair of glasses.
A lot of people who have vision problems consider getting Lasik eye surgery to fix their vision problems so that they won’t have to wear glasses or contacts. On the flip side, there are several risks and problems associated with this procedure, besides the fact that it is very expensive. Contact lenses aren’t expensive, and they are a safe alternative to vision correction.
Keep in mind that contact lenses aren’t available without a prescription. Although you can get certain contacts without a prescription, they won’t correct your vision. To get contacts that correct your vision, you’ll need to visit an eye doctor and get fitted for them. Your doctor will tell you the health of your eyes, as well as the contacts you need to correct your vision.
For several years, contact lenses have been an ideal way to correct your vision. They are more popular than glasses, and they won’t limit what you can and can’t do. Contacts fit snugly in your eyes and they won’t make you feel out of place. You can wear them with any type of clothing you desire – as it is very hard to tell if someone is wearing them or not.
