Contact Lenses are ultra thin lenses laid directly on your eye’s surface
Contact lenses were invented by a German physician in the early 1920s as a means of improving upon the drawbacks of glasses, which includes the high cost and great difficulty in handling and wearing them. Although contact lenses were initially used primarily for correcting vision, there are other significant uses today. Some people wear contacts for sport and recreational activities. Others just wear them for their convenience.
Contacts are soft, clear lenses laid on the eye’s surface to substitute your glasses or contact lenses. Contact Lenses come in two general varieties: disposable and permanent. Disposable contact lenses can be replaced often because they are not designed to be worn long-term. Permanent contacts are meant to be worn for a specific period of time; usually with an optometrist’s prescription.
wear contacts to improve their eye color
Because you may have some refractive errors, whether astigmatism, myopia, presbyopia or other errors, contact lenses offer a way to improve your vision. For those who wear contacts for cosmetic reasons, they are an affordable alternative to glasses. As well, some people wear contacts to improve their eye color.
There are various types of medical devices that correct eye problems, but contacts are probably the most popular ones. In fact, it is hard to find someone who does not own at least one pair of colored contacts. The most popular colors are blue, green, gray, brown, black and white, but you can buy any color you want. These days, you can even buy a pair to match your wedding dress. If you think you might want to change your eye color from time to time, then you should consider decorative contact lenses.
Contacts can be very convenient
But they do present certain health risks. Although contact lenses can prevent infections from occurring, you still need to follow a few hygiene rules in order to reduce the risk of infections. Contacts should always be cleaned or disinfected according to the manufacturer’s instructions. You must not rub your eyes, and you should keep them clean and dry at all times. Some people also prefer to use contact lens drops instead of traditional cleaning liquids or hand sanitizers.
Another problem that often occurs when people wear contacts is dry eye syndrome. Dry eye syndrome is caused by a lack of oxygen within the eye. Contact lenses can contribute to this condition by not allowing enough moisture to enter the eye. This can lead to painful itching, blurred vision and sometimes even pain and redness. If you think you might suffer from this condition, then you should contact your optometrist and ask for advice.
