I have been wearing spectacles for a long time now. I wanted to see how it would be to wear contacts. Many of my friends told me it gave them total freedom. Before deciding to go in for contacts, I thought it would be better if I did some research on my own.

This article is a result of my research work for information on contact lenses.

Contact lenses are thin lenses that are worn directly on the surface of your eyeball. It helps to see clearly without the constant touch and feel of spectacles on your nose.

Wearing spectacles can be very irritating for some; some others may want to totally get rid of spectacles due to the sheer fact that they hate spectacles and some for cosmetic reasons.

Whatever the reason maybe contact lenses make life a breeze for those who do not want to wear spectacles.

The most popular contacts that people choose to wear are the soft contact lenses. There is another type of contact lens called the gas permeable lens.

The gas permeable contact lenses are also known as Rigid Gas Permeable lenses. They are hard contact lenses that are made from a combination of plastic and silicone hydrogel.

Soft Contact Lenses

Soft contact lenses are made of silicone hydrogels. They are soft, comfortable and easy to wear. They easily mold to the shape of the eyeball.

There are different types of soft contact lenses from which you can choose.

Disposable contact lenses

Disposable contact lenses are lenses that you have to use and throw at the end of the day.

With disposable lenses, the chances of infections are less because you use new ones every day.

Extended wear contact lenses

Extended wear contact lenses are lenses that you use continuously for a period and then throw.

For example -

  • contact lenses that have to be changed after a week
  • contact lenses that have to be changed after a month
  • contact lenses that have to be changed twice a month

If you use extended wear contact lenses make sure you clean them well to avoid any chances of an infection.

What are gas permeable contact lenses?

Gas permeable contact lenses are also known as Rigid Gas Permeable lenses (RGP). They are hard lenses made of plastic and silicone hydrogel.

Gas permeable contact lenses were introduced in the 1970s. These contact lenses are made up of plastic and silicone. A unique feature of gas permeable lenses is that they allow a thin stream of air to pass through between the eyeball and the contact lens.

Due to this, there is less discomfort while wearing the gas permeable lens because the lens does not sit directly on the eyeball. Gas permeable contact lenses provide better vision, and they last for a longer time.

Gas permeable contact lenses come in bifocal and multifocal designs just like spectacles.

The advantages of gas permeable contact lenses -

  • they need to be replaced only after a period of two years
  • they provide sharper vision than soft contact lenses

The disadvantages with gas permeable contact lenses -

  • they take some time to get used to whereas soft contact lenses are instantly comfortable
  • they are more expensive than soft contact lenses

Who should not wear contact lenses?

If you are prone to any of the following conditions then it is best to avoid wearing contact lenses-

  • dry eyes
  • severe allergies
  • prone to frequent eye infections

If you feel that you do not have the patience to take proper care of contact lenses, then the best option would be to wear spectacles.

Parents should decide whether their children are responsible enough to take care of their contacts.

How to clean your contact lenses?

The very first thing to do before cleaning your contact lenses is to wash and dry your hands with a lint-free towel. Use a lens cleaning solution to clean your contact lenses.

Gently remove the contact lens from your eyes.

Pour a stream of the lens cleaning solution on the contact lens and rinse thoroughly.

Fill the contact lens case with the lens cleaning solution and soak overnight.

Remember to wash the contact lens case first with hot water and then with the cleaning solution. Let it air dry before filling it with the lens cleaning solution again.

Best thing to do is to have two contact lens cases so that when one is being air dried you can use the other case to store your contacts.

The contact lens case has two compartments in different colors, one for the left eye contact lens and one for the right eye contact lens. Do not interchange the lenses.

What not to do when you wear contact lenses

  • Do not rub your eyes vigorously
  • Do not wear your contact lenses if you have an eye infection
  • Do not swim with your contact lenses
  • Do not keep your lenses outside the lens case even for a few minutes
  • Do not wash your contact lenses with tap water
  • Do not try to remove your contact lenses immediately after you get up
  • Do not share your contact lenses
  • Do not wear the right contact lens for the left eye and vice versa

Colored Contact Lenses

Colored contact lenses are lenses that are worn to change the color of the eye. Colored contact lenses must be treated the same way you treat prescription lenses. You have to take care of them and store them the right way.

If you are going to use it for special occasions, then you should store your contact lenses properly to avoid infection. Colored contact lenses have to be fitted by an eye doctor.

Do not buy it online and wear them you may end up hurting your eye.

      As someone who wore lenses for over 25 years, this is useful advice. Fortunately I was later to have LASIK surgery (I wrote a hub about the trials and tribulations I had with my eyesight as a child) so no longer have any need for them but at the time, contact lenses opened up a new world for me.

      Being a successful contact wearer since 1985 i can think of a few more tips. most importantly DO NOT PUT THEM IN YOUR MOUTH TO CLEAN THEM IN PLACE OF CONTACT LENS SOLUTION! That method is old school, it used to be suggested for hard lens contacts but is a NO NO now a days. There are many options now a days for different types of lens and each one has a different application for different people. I would say hunt down a really GOOD eye doctor. Even though i have had very good success with contacts my current eye doctor determined that in reference to my prior prescription I was what is described as "over prescribed" meaning my prescription was too strong and she had me in a different strength for each eye. My current doc now has me in the same strength for both eyes even though each of my eyes are different I wear Multi-Focus by Air Optics ( soft daily wear lens and I LOVE them) . That is working much better for me. Secondly DO NOT mix brands of contact lens cleaners. I found out the hard way years ago that can cause an eye burn. Follow the cleaning instructions for your contact lens brand to the letter. Each type is slightly different. Also do not over wear your lens either for total time during the day or more than the recommended number of days until you throw them away and open a new pair. Over worn lens build up proteins, dirt and gunk that is invisible making lens fog and setting the wearer up for infection. Good basic information in this hub.

      I've worn soft contact lenses for years. When I first started, they were not the extended wear or disposable kind available now. I especially like the daily disposable. They feel like new eyes everyday. That also makes you less likely to have infections because you are actually tossing a pair each day. The down side is that it can be expensive so its a good idea to invest in both kind if you are a contact lens fan.

      Thanks for your useful information. Cleaning is the key and you can never be too cautious.

      I wore the soft contact lense for about ten years and I loved them. This article is very good. Contact lense can harm the eyes if not cared for properly. Well done...

      I've worn glasses for sixty years now. I would feel naked without them, which explains why I've never had contacts. Good information here.

      This is very useful and informative hub for those who wear or want to wear contact lenses.

      My son used to wear it once, but it needed lot of care, while wearing it or taking it out and especially while driving his motorcycle. So again he was back to his glasses.

      Very useful hub, voted up and thanks!
