Contact Lenses Corrective

Corrective contact lenses have been in existence for many decades. They’re a popular alternative to glasses and offer a wide range of vision-enhancing capabilities.

Many different styles of corrective contacts are available, including soft contacts, hard contacts, daily contacts and more. Talk with your eye doctor to be fitted with the style that is most comfortable and best suited for your eye condition.

Correcting Eye Problems with Contact Lenses

Many individuals experience mild to severe vision limitations. Contacts can correct most common sight problems, including:

  • Astigmatism: an irregular eye lens that makes objects appear oddly shaped
  • Hyperopia (Farsightedness): the ability to see objects at a distance but not up close
  • Myopia (Nearsightedness): the ability to see objects up close but not at a distance
  • Presbyopia: hardening of the lens that causes blurred vision; typically occurs as people age.

Types of Corrective Contact Lenses

Today, there are two basic types of vision-correction lenses on the market:

  • Rigid Lenses: Also called gas permeable, oxygen permeable or rigid gas permeable (RGP), these lenses can correct vision problems and won’t tear easily.Because RPG lenses last several months, clean them very carefully and thoroughly on a daily basis. These contacts may feel uncomfortable for some new wearers but, in time, become unnoticeable.
  • Soft Lenses: Crafted from a flexible plastic that also breathes, soft lenses are generally more comfortable than RGP lenses. However, they do tend to tear easily.Soft lenses offer additional options for short or long-term use. Sometimes categorized as planned replacement lenses, they feature a range of features to fit most lifestyles. Here are some styles of soft contacts:
    • Continuous Wear: These lenses are worn on a continuous basis, even while the wearer is sleeping. You should replace continuous wear lenses on a planned schedule, generally at one week, two weeks or four weeks.
    • Daily Disposables: Daily disposable lenses are thrown away after a single use.
    • Disposable: With disposable lenses, you remove them for cleaning and disinfecting and discard them at two- or four-week intervals.
    • Extended Wear: Sometimes called daily extended wear lenses, extended wear lenses allow individuals to take naps without having to remove the. However, you can’t sleep overnight in them. Wear these lenses for up to 30 days and then discard them.

Fairly new to the market, hybrid lenses blend the best features of hard and soft contacts. They provide a soft outer ring for comfort and a rigid core for greater visual acuity.

Who can Wear Corrective Lenses?

If you have been told in the past that you can’t wear contacts, ask your eye doctor about them again. Contact lens technologies have advanced rapidly, especially in the last decade. Even people who suffer from severe astigmatism can now find corrective lens options.

In some instances, however, an individual may not be a good candidate for corrective lenses. Consider alternatives if you:

  • are exposed to fumes or chemicals on a consistent basis
  • are prone to eye infections
  • experience extreme dry eye or if your tear ducts are somehow impaired
  • suffer from specific allergies
  • work or live in areas that are consistently windy and dusty.

You should also avoid corrective contact lenses if you will not be able to care for them properly. While daily disposables do not require cleaning, other styles of contacts must be cleaned and cared for properly in order to avoid eye problems, such as infections.

How to Purchase Contact Lenses

By law, you must have a valid prescription to purchase contact lenses. In most states, your prescription is good for one year. If you also wear glasses, you will need to have a separate prescription written for contact lenses, especially when planning to make a purchase through someone other than your eye care provider.

Ordering contact lenses from Internet retailers sometimes, but not always, will save you some money. However, it pays to shop around. Call various corrective lens retailers in your area to compare rates and find the best deal.
