How To Prescription Eyeglasses And Glasses – Proper Care And Maintenance Of Your Contact Lenses

the basics of contact lenses

Contact lenses, also known as lenses, are slender thin contact lenses placed directly onto the cornea of the eye. Contact lenses are one of only a few ways to get a permanent image made directly onto the cornea. The most common reasons that people wear contact lenses is to correct vision, although there are also those who wear them for cosmetic and therapeutic reasons. In this article, we will cover the basics of contact lenses.

As we have mentioned before, contact lenses are one of the only ways to get a permanent image made directly onto the cornea. It’s important to note that all manufacturers are required by law to clearly indicate how their contact lenses work, and how they will affect the wearer. The most common form of contact lens is the gas permeable (GP) lenses, which allow some amount of gas to pass through the eye, improving the flow of oxygen. Most of the time, the gas that is allowed through is a pure oxygen, however sometimes doctors prescribe higher levels of oxygen to patients with eye conditions such as chronic astigmatism. There are also disposable PMMA lenses, which are basically the same technology as GP lenses, except they use a metal shell to increase the level of oxygen permeability.

poor visual clarity

There are many different reasons why a person may need to obtain a contact lens prescription. One of these reasons is to correct refractive errors. Patients who have poor visual clarity and need to wear contact lenses in order to see clearly are often required by their optometrist to have a contact lens prescription. Also, individuals who experience the effects of cataract surgery are required by their doctor to have a contact lens prescription. These individuals often experience extreme dryness of the eye, which can make it difficult to see, as well as causing other health issues such as itching and redness.

In addition to correcting refractive errors, contact lenses may be prescribed for astigmatism and myopia. Astigmatism occurs when the front surface of your eye is slightly irregular in shape; this irregularity causes the eye to focus light in a different direction. Myopia, on the other hand, occurs when the front surface of your eyes does not properly focus light. Because having astigmatism or myopia makes it difficult to see clearly, it can make driving or performing other tasks extremely dangerous, as objects that are nearsighted are magnified many times over when driving or during other activities.

wearing contact lenses

When you are wearing contact lenses, it is very important that you follow the instructions provided by your optometrist and your contact lenses manufacturer. These instructions will specify the frequency of contact lenses you should wear each day, as well as the strength, frequency, size, and materials of your contact lenses. For example, if you are prescribed a strong lens, you should always wear your contact lenses at their strongest strength when you are awake.

You also may have to change your contact lenses every week or two if your eyes become dry. If your contact lenses are becoming uncomfortable because they are rubbing against your cornea or the skin around your cornea, they should be gently shifted to a new location where they will not cause irritation. If you notice any changes in your eyes, visit your optometrist right away. It may be necessary for you to wear prescription eyeglasses instead of contact lenses for awhile. However, once you get your contact lenses cleaned, you will find it very easy to wear your prescription glasses whenever you desire.
