What You Need to Know Before You Wear Contact Lenses

Contact lenses, also known as artificial lenses, are artificial lenses placed on the corner of your eyes. Contact lenses were invented in the 1970s as an alternative to eyeglasses, which were extremely cumbersome and unattractive. Today, contact lenses come in a variety of styles, including disposable and custom-fit options. They can also be used to correct vision by astigmatism, nearsightedness or farsightedness, and to improve your eye’s natural color.


The first group of people who wear contact lenses is the elderly

Because they have eye problems like astigmatism, nearsightedness, or farsightedness, wearing corrective lenses is a convenient way to improve their vision and improve their self-esteem. The second group of people who wear contact lenses is those with astigmatism. Some people experience astigmatism in one or both eyes. When they wear contact lenses, their vision is corrected for both eyes. And, sometimes, they may find that their glasses give them better vision at night.


There are two basic types of contact lenses

The gas permeable and the rigid gas permeable. Gas permeable contact lenses are available in either soft or rigid gas permeable varieties. Both varieties allow a small amount of gas to escape through the top layer of the lens, improving vision while reducing the risk of irritation. Rigid gas permeable contact lenses are more durable and versatile than soft gas permeable lenses.


Once you visit an optometrist to get your contact lenses

He or she will make a selection based on your needs. If you’re new to wearing contact lenses, your optometrist will place a specially fitted solution in a small insert that matches the shape of your eye. This solution will allow your eyes to breathe, which is very important when you’re wearing lenses. Once this is done, your contact lenses will be ready to go. You can choose from many styles and designs, just as you would with glasses. Just remember that your optometrist is the only professional who knows what will suit your needs best.


There are two basic types of design for contact lenses

The wavefront and the sclera. The wavefront is the normal shape that your cornea that should be curved in order to focus light correctly. The sclera is the outermost surface of the cornea and determines how your eyes perceive color. Your optometrist will take a look at your cornea and give you advice on which shape and design would best suit your vision.


Wearing contact lenses is an easy way to improve your vision

Without having to undergo extensive and costly eye care. In most cases, people begin by wearing soft contact lenses. As you progress in your eye care, you may be asked to switch to a stronger solution or even get custom-made ones made. If you wear contact lenses for the first time, however, you can enjoy the benefits of having a clearer vision.
