Wearing Contact Lenses
Contact lenses sit right on top of your cornea, with a layer of natural tears in between. The tears make the lens more comfortable because they reduce friction. When you don’t have enough of your own tears, you may have to add drops of a special solution.
This solution is similar to natural tears. Many people that don’t wear contact lenses often need eye drops as well. When your eyes are irritated because of environmental issues, illness or allergies, these drops can greatly reduce discomfort.
All of these issues are worsened by wearing contact lenses, so the need for eye drops increases. When you wear contacts, your eyes may dry out more than if you don’t. Although new technology has made the lenses more breathable, under certain conditions your eyes may still not get as much oxygen as they need.
Tears or eye drops can also wash away any dirt that may come in contact with your eyes. When dirt gets trapped in between the lens and your cornea, you could develop very serious problems. Your eyes could become infected or scratched. You should not wear contact lenses if your eye is infected or injured. That is one of the reasons why people that wear contact lenses always have a backup pair of eye glasses.
Just like the lenses in your eye glasses are specially created for your vision problems, the lenses in contacts are as well. They are created using the same prescription as your eye glasses. They are crafted to correct your particular vision problem. That means that they can correct astigmatism, presbyopia, nearsightedness or farsightedness.
Only a specially trained eye doctor can tell you what type of glasses you need. You have to have a prescription form a certified optometrist in order to obtain eye glasses or contact lenses. You may have seen plenty of contacts at http://www.contactsjudge.com/ offering prescription glasses at greatly reduced prices, but you still have to know what your prescription is before you can order.
Getting the wrong prescription won’t help you see better. That means you have to first go to an eye doctor and get a prescription. Once you have the exact details of your eyes and vision problems, you can order your glasses and contact lenses from anyone you wish.
