Spectacle corrections used to be the correction of choice In the past. With modern technology, people are now choosing contact lenses as an alternative or backup to eye surgery or spectacles.
The reason is that contact lenses are becoming safer and safer every day. They also cost much less than they used to. Roughly 30% of the world’s vision corrections are contact lenses. In America alone, over 34 million people wear contact lenses.
So what are the best contact lenses?
There are two types of contact lenses, rigid (hard) contact lenses, and soft (flexible) contact lenses. A rigid or hard lens is a small thin plastic that fits over the cornea of the eye. Flexible or Soft lenses are slightly larger and are made of thin plastic that absorbs fluid. Rigid lenses come as nongas permeable and gas permeable. Gas permeable lenses allow more oxygen to the eye and float on a tear film on the cornea. People with high astigmatism and irregularly shaped corneas see much better with this type of lens.
The soft lenses are usually more comfortable to wear and are the favoured lenses of choice by most eye doctors. In recent years disposable lenses have made contact lenses even more popular. These are lenses that can be worn for a specified period and then discarded. They are usually more expensive, are more comfortable and help reduce the risk of infection. Some of these lenses can be worn overnight, but it is highly recommended that they are taken out before going to bed to prevent the risk of infection.
Contact lenses can also be worn for cosmetic reasons. They are available in various colors and help give the appearance of a different eye color. Some of the best contact lenses are made for dramatic effects such as cat’s eyes. These are great for events such as Halloween or Carnival. Most of these contact lenses are also available in prescription form.
Contact lenses are an alternative to eyeglasses. There are some people who do not like the look and feel of eye glasses. Some tend to lose their glasses a lot and as such contact lenses are a great alternative. People who wear contact lenses are required to check their eyes more often than those who wear normal glasses. People with severe allergies, frequent infections, and dry eyes are not advised to use contact lenses. There are also other conditions that do not allow the use of contact lenses. Your eye doctor can advise you on this.
