contact lens

A contact lens, or simply contact or CL, is a thin lens placed directly on the surface of the eye. CLs are considered medical devices and can be worn to correct vision, or for cosmetic or therapeutic reasons.

Many people use contact lens in different reason, I have a friend who use it just for style or fashion but I also no people who use it because their eyes is "malabo". The Contact lens can help people who had problem in their eyes or vision, instead of using eye glass they can use contact lens. The lenses helps you to see better and at the same time it adds to your fashion.

Here are the advantage of contact lens, 

• Contacts sit directly on your eye, so vision, particularly peripheral vision, is unobstructed.
• You can participate in sports and outdoor activities without fear of eyeglasses getting in the way, falling off or breaking. 
• You can even change the color of your eyes with color contact lenses.
• Contacts conform to the curvature of your eye, providing a wider field of view and causing less vision distortions and obstructions than eyeglasses.
•  Contacts typically aren't affected by weather conditions and won't fog up in cold weather like glasses.
• 
  

Here are the disadvantage of contact lens, 

• Some people have trouble applying a contact lens to their eyes.
• Contacts reduce the amount of oxygen reaching your eye and can cause or increase the severity of dry eye syndrome.
• If you work at a computer often, wearing contact lenses will likely contribute to symptoms of computer vision syndrome.
• Contacts require proper lens care and lens case cleaning each day, to avoid potentially serious eye infections. If you can't commit to the care and recommended replacement cycle of your contacts, consider daily disposables.
• If you accidentally fall asleep while wearing daily wear contacts, your eyes typically will be dry, gritty, red and irritated when you wake.
