To see from a medicinal perspective, contact lenses are worn to correct myopia (nearsightedness), hyperopia (farsightedness) or astigmatism. Besides, there are also contacts available to enhance or change the color of the eye with or without a prescription for visual correction. Theatrical contacts are also available to give the eye an appearance that matches a theatrical costume like a cat or zombie. We can say, contact lenses benefit many style person.
Contact Lens Types
- Soft Lenses: The most commonly prescribed contact lens are these gel-like containing plastics the size of the iris of the eye. More recently, the silicone hydrogel lenses have been introduced and are generally preferred by practitioners since they allow more oxygen to pass between the lens and the eye and are less likely to dry out.
- Hard Lenses: Made from PMMA, which is plexiglass or lucite, these lenses are almost never used anymore but may be preferred or required by the patient.
- GP or RGP Lenses: These are “oxygen permeable” lenses that are stiff, waterless plastics geared toward patients with presbyopia and a high astigmatism and a smaller than the iris of the eye.
Contact Lens Wear
- Daily Wear contacts can be worn throughout the day but must be removed and cleaned nightly. Daily wear contact lenses come in different durations of wear time and must be eventually disposed of and replaced with a fresh pair. There are contacts that are disposed of daily, weekly or monthly depending on the preference as well as the visual needs of the patient.
- Extended Wear contacts can be safely worn overnight or up to 7 consecutive days without removal. Continuous wear lenses are a type of extended wear that can be worn for up to 30 consecutive nights without removal.
There are also contact options available for more severe eye diseases and may need to be custom made to fit and serve the purpose of a special needs situation. Almost anyone these days can wear contacts, in fact 1 out of 5 people in the U.S. is a contact lens wearer. Whether the purpose for contact lens wear is a replacement to glasses or for more aesthetic purposes there is bound to be a healthy contact option available for everyone.

Even though you can get non prescription contacts, they aren’t meant to correct your vision. Known as plano, the most common type of non prescription contact lenses are the opaque color contact lenses. Even though they don’t require a prescription, those who want them need to consult with an optometrist first to ensure they get the right fit.
Locally or on the Internet, you can find many different varieties of non prescription contact lenses available. You can find lenses that enhance the natural color of your eyes, lenses that enhance your look, and many others. There are also Halloween contact lenses as well, which are great for Halloween or other times when you want to look different.
With non prescription contact lenses, you’ll have the choice of daily wear and disposable lenses. If you are looking to change colors on a frequent basis, disposable lenses may be your best choice. The best thing about disposable lenses is the fact that you don’t need to clean them at all, simply wear them during the day then take them out and discard them at night.
If you are going to use the same color or the same pair of contacts for a while, you may want to go with daily wear lenses. Daily wear contact lenses will last you a lot longer than the disposable lenses, although they will need to be disinfected and cleaned on a regular basis. As long as you clean and disinfect them on a regular basis, they will last you for quite a while.
Without the supervision of a doctor, may doctors don’t advise the use of non prescription contact lenses. Doctors will tell you that when they don’t monitor the fitting, usage of the contacts, and the overall effects, they may cause you serious problems and possibly even blindness. While a lot of people use non prescription contacts, few of them experience serious problems.
When an individual buys non prescription contacts without going to see an optician, they tend to forget the fact that contacts aren’t for everyone. The amount of tears, shape of the eye, and need for correction varies from person to person. To get the right fit, you must consult an optician, as he will need to carefully examine you.
Even though they may work great for some, non prescription lenses aren’t for everyone. Anytime you use them, you should be very carefully and take the necessary care for your lenses. If you are a diabetic, you’ll need to be very carefully, for the simple fact that eye infections will take a long time to heal. Even though you may not get an infection, there is always a small chance that it could happen. Therefore, you should always be carefully anytime you use these types of contacts.
