Buying a Contact Lens – How Do I Choose the Right One?

The contact lens contains a gas such as oxygen

Contact lens, also called lenses, are small, thin lenses placed on the cornea (the transparent cover of the eye). Contact lenses come in different styles, including bifocals (two different powers at the same time), multifocal (which allows you to read either word or letters), and trifocal (for close-up reading). There are also toric contact lenses, popularly known as “ball & sphere”, that are a special type of two layered contact lens that provides extra coverage in the front.

If you have vision problems, contact lenses are an excellent alternative to glasses because they are comfortable, secure, provide clear vision, and are affordable. However, if you’re looking for a good price, then you should shop around to see what the prices for different types of lenses are in your area. One way to do this is to go to your local optometrist and have him or her take a look at your eye health. In many cases, your eye doctor will run a series of tests to determine how healthy you are and if you’re likely to need reading glasses in addition to contact lenses. Then he or she will be able to give you some price comparisons based on that information. Here’s a quick contact lens comparison that some Optometrists have developed.

For Soft Contact Lenses

These lenses can be either soft or rigid. They are made with a variety of materials, including polycarbonate and carbon fiber. There are several different designations for these lenses: normal, hyperopia, and farsighted. Hyperopia lenses to correct nearsightedness, often called myopia; astigmatism makes the vision of objects distorted, nearsighted or farsighted. Farsighted lenses can also help with astigmatism, but are more often used for recreational reasons. Many people with farsightedness choose soft contact lenses because they allow more focus on close objects.

o Hard Contact Lenses: These lenses have two separate powers, one for distance and the other for near sightedness. Some of them have built-in distance and near sight correction, but most of them use a separate power for both purposes. The main difference between hard and soft contact lenses is the amount of astigmatism correction that can be done. Both are designed to reduce the problems caused by nearsightedness, myopia, and farsightedness, but hard lenses can correct these problems more completely than soft lenses.

Extended Wear Contact Lenses

As the name implies, extended wear contact lenses are worn for an extended period of time. These can range from several months to several years. Some of them will allow you to see well enough to drive, do housework, or read, while others will allow you to be able to see things clearly enough to be around people. There are many advantages to wearing these long-term contacts, such as the fact that they do not require the maintenance of rigid gas permeable lenses or soft contact lenses, which means less cleaning and fewer problems with dry eyes or fogging.

Disposable: If you wear disposable contact lens, your contact needs to be replaced each month. You purchase the disposable at the store where you buy your contacts, usually in a three-pack. The three packages contain one each of a cushion, binder, and lens. Usually, you replace the entire three pack over three months, although in some cases you may only need to replace one of the two packages during this time, and then you need to purchase a new soft contact lens.
