What Is the Best Contact Lens?

Contact Lenses are bifocals

Contact Lenses, also known as full-liners, are thin plastic lenses usually placed directly on top of the iris (the colored part of the eye). Contact Lenses are highly popular ocular prosthetics and they are used by more than 150 million people around the world, either for corrective vision, such as astigmatism, or for other cosmetic or aesthetic reasons. Contact Lenses come in various shapes, sizes and colors. Some Contact Lenses are bifocals (two different shades of color), some have monochromatic colors (both red and blue), and others have farsighted versions. Some are disposable and some are long-term wear, making it possible to constantly change your eye color depending on your mood or the season.

Contact Lenses correct many common vision problems that occur with the human eye, such as nearsightedness, farsightedness, presbyopia, and astigmatism. The main function of Contact Lenses is to alter the shape of a person’s eye by creating a more or less spherical curve to the cornea. This change enables the user to better perceive depth and distance. Contact Lenses also allow for increased light sensitivity, which improves night vision greatly.

wear Contact Lenses overnight

Contact Lenses differ from traditional glasses because they contain no gas, such as rigid gas, which is present in conventional glasses. With rigid gas, light cannot escape from the lens because it is tightly sealed. Contact Lenses contain gas pockets that allow light to escape, thus providing a clearer vision field. However, these gas pockets also make the wearer’s eyes uncomfortable, causing them to often wear Contact Lenses overnight.

The purpose of a comprehensive eye exam is to determine a proper prescription and to determine which vision correction techniques will be most effective. Vision tests commonly involve a thorough examination of the visual field, including the ability to see small details at various distances and to see fine details at greater distances. If you have had a recent eye surgery, your optometrist may order an eye exam to determine the appropriate contact lens prescription. In most cases, the results of this test are not complete unless your optometrist has determined the exact level of corrective eyeglasses to be worn. Contact lenses that do not provide the full effect of corrective eyeglasses will not be approved.

soft or rigid gas permeable

Contact Lenses can either be soft or rigid gas permeable, meaning that some of them will fit better than others. Some factors, such as age, color, and application will play a role in which type of Contact Lenses will be most appropriate. Some patients, such as people who suffer from color blindness, may benefit from soft disposable contact lenses. The stronger the bond between the toric lens and the eye, the more visible the toric will be. This means that people with strong bonds will be able to wear contacts longer before the need for replacement drops or other supplies may arise.

For those looking for a less obvious choice, rigid gas permeable (RGP) lenses are an alternative to soft lenses. Because RGP lenses require no sealing, they provide a more comfortable fit and greater visual clarity. However, because the RGP lens is more translucent, it has a smaller viewing area than most soft contacts. Because of its larger viewing area, however, the RGP lens is often used for individuals who wear contacts regularly, but who desire an enhanced appearance. These larger clear eyes may compensate for the smaller clear areas of a rigid lens, resulting in a cosmetic improvement.
