Recent technology in soft contact lenses has made it more convenient and comfortable for people to wear them than ever before. For those with vision problems, this innovative development provides people with exciting options and freedom from their glasses. In addition to the possibilities of changing your eye color, soft contacts can be worn for long periods of time and reduce the irritation to the cornea. The Contact Lens is a major contribution for people who are nearsighted, farsighted and can be effective for those who require bifocals or have astigmatism.
Eye Anatomy
The cornea is the clear covering of the eye that requires oxygen and constant lubrication from natural body fluids to prevent drying and irritation. Soft contact lenses are made of a thin plastic and water that float on the cornea and are permeable to oxygen. As the wearer adjusts to the sensation and builds a tolerance to this thin lens, the eye receives the important oxygen and lubricants that are necessary for comfort and the prevention of dry eyes.
Hard or Rigid Contact Lenses
Although all contact lenses do have potential to cause eye irritation, many people have experienced more discomfort from the gas-permeable hard contact lenses. Some people claim that the hard lenses provide better vision, while others state that they are uncomfortable and are unable to tolerate them in their eyes. Soft lenses are instantly more comfortable on insertion and many people prefer them over the hard version.
Maintenance of Soft Contacts
The development of the soft lens has provided several different types that require little or minimal cleaning and care. The disposable contact is an excellent option for those who desire the convenience of an available fresh, clean pair of lenses every day. In addition, disposable contacts have the benefit of reducing the occurrence of eye irritation. Each pair is aseptic and the sensitive eye is not exposed to cleaning solutions or the chance for the growth of bacteria. Other lenses are worn safely for up to a year and require minimal cleaning and maintenance.
Find the Right Contact Lens for You
If you desire a break from your glasses or wish to change your appearance, contact lenses may be a great option for you. Only your eye doctor can examine you and decide if you are a good candidate for contact lenses.
