A contact lens is a practical way of changing the color of your eyes
It is similar to wearing glasses but provides a good alternative if you do not like wearing eyeglasses. However, you need to know that there are some risks involved in contact lens application and use. There have been reported cases of blindness and eye injury caused by faulty or substandard contact lenses. Here are some facts you should be aware of when it comes to contact lens use and handling:
Most people who wear contact lenses do so as a simple fashion accessory. They enjoy the pleasant effect of changing their eye color and improve their appearance. Contact lenses, also known as contact lenses, are tiny thin lenses usually placed right on the cornea surface. Contact lenses are an ocular prosthesis used by more than 150 million individuals worldwide, and they are commonly worn to alter vision for aesthetic or corrective reasons.
The sale and distribution of contact lens products in the United States follows a complex process
Contact lenses come in two varieties, either soft lenses (also called gas permeable, or GPL) or rigid gas permeable (RGP), and each type has its own advantages and disadvantages. Soft lenses typically are much easier to wear and adjust to, which is why many sufferers prefer them. In addition, contact lens wearers generally have much faster wearers’ recovery time after a surgery than those using RGP lenses. However, RGP lenses typically have a shorter lifespan when it comes to correcting astigmatism than soft lenses.
The Federal Food and Drug Administration (FDA) regulate the production and distribution of cosmetics, including contact lenses. In the United States, all contact lens manufacturers are required to submit detailed information regarding their manufacturing processes to the FDA. In most cases, the manufacturer submits these documents in conjunction with the filing of a New Drug Application, or NDA, with the FDA. The FDA regulates the amount and type of ingredients that may be contained in contact lenses and the safety of packaging materials and devices used to manufacture them. It also oversees the quality of the finished product, ensuring that it meets the requirements of the FDA and that it is free of defects and damage.
the eye doctor will prescribe either soft lenses or rigid gas permeable lenses
When you choose between the two, you should be aware of your eye history and what treatment you may need to treat your particular eye problems. For example, people with nearsightedness, farsightedness, presbyopia, and astigmatism may all require different lenses to correct their vision.
If you have vision problems, you may also be able to purchase monovision contact lenses. Monovision is when one eye receives an image while the other eye stays clear. This allows the person wearing the contacts to see both eyes at the same time. Monovision contacts come in a variety of styles and prescriptions, so it is important to talk with an optometrist or other health professional before making the decision to purchase monovision contacts. Some contacts are more comfortable than others, but if you are having any kind of problem, talk to your eye care professional before making your purchase. They can provide the information that you need to make an informed decision about your contact lenses.
