  • never buy or order contact lenses with an expired prescription
  • make sure the site is reliable and the products are of good quality
  • if you receive other brand or a different prescription than the one ordered return the product for a refund.

Daily lenses must be removed nightly and they are said to be healthier than extended wear ones that can be worn overnight, usually for seven days successively without removal.

A cosmetic contact lens is designed to alter the appearance of the eye. These lenses may also improve the vision, but some blurring or obstruction of vision may occur as a result of the color or design.

These lenses are used mainly in the entertainment industry to make the eye appear agreeable, remarkable or unnatural in appearance. And last but not least therapeutic contact lenses are soft lenses that are often used in the treatment of non-refractive disorders of the eye. A bandage contact lens protects an injured or unhealthy cornea from the regular rubbing of blinking eyelids thereby permitting it to heal.
