Types of Contacts

Confused about contacts? Advances in contact lens technologies have created many options in addition to hard and soft lenses. Today, contact lenses are likely to be described in one or several of the following ways.


The vast majority of people requiring vision correction can wear contact lenses without any problems. New materials and lens care technologies have made today's contacts more comfortable, safer and easier to wear. Consider the questions and answers below to help assess whether they're a choice you should consider.


Ultra Violet (UV) light is harmful to more than just your skin. Certain eye conditions, such as macular degeneration, photokeratitis, and cataracts, are also caused by exposure to UV light.


Good vision is vital to reading well. And although vision may not be the only cause of reading difficulties, it is one that is sometimes overlooked.

Eight vision skills needed to read


Eye care experts generally agree: Watching television will not harm your eyes or vision if the TV room is lit properly and if you follow a few viewing tips. In fact, there is usually less strain involved in TV viewing than in doing close work such as sewing or reading. But TV watching for long stretches of time can leave your eyes fatigued.


Retinal disorders
Retinal disorders have a greater chance of developing in older adults, due to the aging process. These often impair central vision. Advances in eye and health care have made treatments more successful, with chances of maintaining good vision now better than ever. Conditions once considered sight threatening may now be successfully treated if diagnosed early.

Suggestions for better sight


Most changes in vision occur in the early and later years of life. Although some people may discover they have nearsightedness -- or difficulty seeing at a distance -- as late as their mid-20s, vision typically stabilizes during the late teen years. From then until around age 40, vision typically changes little, if at all.

Presbyopia - Age-related loss of close-up vision
At about 40 years of age, seeing to read or do close work such as sewing may become difficult. This is known as "presbyopia." Presbyopia, a name that comes from the Greek words for "old eye," occurs because the crystalline lens, an essential component of the eye's refractive, or light-bending structure, loses flexibility as it grows thicker with age. This lack of flexibility affects the ability to focus on close objects.


Teach your child eye protection through these safety rules:

  • Keep away from the targets of darts, bows-and-arrows, air guns and missile-throwing toys.
  • Don't shine laser pointers into anyone's eyes.
  • Teach them laser pointers are not toys.
  • Don't run with or throw sharp objects.
  • Wear safety goggles when using chemistry sets, power tools and household and yard chemicals. (Note: Be certain your child is mature enough to handle these items safely, and provide proper supervision.)

Why thorough vision examinations are important

Don't assume your child has good vision because he or she passed a school vision screening. A 20/20 score means only that your child can see at 20 feet what he or she should be able to see at that distance. It does not measure any of the other vision skills needed for learning.

Vision screenings are important but they should not be substituted for a thorough vision examination.

Things you can do

About 80 percent of all babies are born farsighted -- able to see objects clearly at a distance but less clearly close up. Some five percent are born nearsighted, or unable to see objects at a distance clearly.

Approximately 15 percent are born with nothing wrong with the refractive parts of the eye -- the cornea and crystalline lens which bend light and focus it properly on the retina. Farsightedness usually decreases as a child ages, typically normalizing to a negligible value by the age of 7-8.
