Facts About Contact Lenses That You Should Know
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.
