Finding a Contact Lens for Dry Eyes
Have you ever heard about a contact lens for dry eyes? Like many others, you might just be surprised to hear about it. This is because millions of people actually get dry eyes because of wearing contact lenses. Is it ever possible for contact lenses to help reduce dry eyes instead?
Dry Eyes
We all know what we need tears and eye moisture for. They are the eyes’ number one defense against dust, particles and organisms that can do damage to the eyes. Not all of us though have sufficient eye moisture all the time. Those who do lack moisture end up suffering from the symptoms of dry eyes such as itchiness and discomfort.
There are a couple of possible causes for the loss of moisture. Dry eyes can develop in people who are fast approaching the golden age. Other possible causes include some types of medicines, constant exposure to dirt and frequent use of air conditioning. One other common cause is prolonged staring at the computer or at work papers. Those who wear contact lenses also tend to be more prone to dry eyes.

Contact Lens Can Causes Eye Problems
Contact lenses are small plastic discs shaped to correct an eyesight problem such as nearsightedness, farsightedness, presbyopia, or astigmatism. These are called refractive errors. They may also be used by people who have had surgery for cataracts.
Features of Contact Lenses
The lenses are made from different types of materials – soft and rigid – and come in a variety of designs and colors. These include disposable, colored, astigmatic, aphakic, presbyopic and keratoconic lenses. The initial fitting and follow up care are important parts of contact lens usage to give maximum benefits of vision, appearance, comfort and tissue integrity.
An old lens that becomes uncomfortable may be developing deposits on the lens, scratches or nicks in the lens, or problems with the tears lubricating the surface of the lens. People are different with how long a given lens will remain comfortable, and good care of lenses will usually extend the life of a lens. Having to replace lenses frequently due to rapid protein deposit formation or other problems is a good reason to consider disposable lenses.
Change Your Eye Color With Colored Toric Contact Lens
Have you suffered from blurry vision even when you’re wearing contacts? If you have you might ask your doctor about astigmatisms. As a child I was diagnosed with astigmatism, but it was mild and at the time my eye doctor did not warrant a special corrective lens for the problem. My last eye doctor told me I should have Toric contact lenses if the blurriness was too distracting. You may find you have astigmatism, but it has been mild enough the eye doctor hasn’t mentioned special lenses. If this is the case and you wear colored contacts now don’t worry you can still wear colored contact lenses. The producers of Toric contact lenses provide them in color depending upon your eye prescription.
When you are looking for colored Toric contact lenses it may be as simple as asking your eye doctor for the retailers who provide these lenses or you might like to do the research yourself. Online retailers will have catalogs with the colored contacts they supply and they will mention if that lens comes as a Toric contact lens.

7 Contact Lens Safety Tips
Contact lenses are extremely popular world over as fashion statements and to improve eye sight. The lens when wearing a contact lens is placed right over the cornea. The cornea is defined as the clear front portion of the eye where light rays are bent and focusing occurs. The cornea has no blood supply and derives oxygen directly from the air itself.
According to ophthalmologists and other doctors who specialize in diseases of the eyes, those who wear contact lenses must protect the cornea from problems like the abnormal growth of blood vessels and irritations caused by lack of oxygen and chemicals.
Contact lens wearers must be aware of safety procedures and be sure to observe them:
- Avoid the temptation to wear colored contact lenses. Studies have shown that colored lenses worn in the eyes reduce the amount of oxygen that reaches the cornea. The FDA has reported that decorative colored contact lenses can cause: conjunctivitis, corneal edema, allergic reactions, corneal abrasions, reduction in vision, sensitivity such as inability to contrast and so on.
Varieties of Contact Lens Solutions
Taking care of contact lenses by cleaning and disinfecting and storing them is much easier now a days. Most people use multi purpose” solutions -that is the same solution used to clean disinfect and store the contact lenses. There are preservative-free solutions containing hydrogen peroxide for people who are sensitive to the preservatives used in solutions. There are various kinds of solutions used for contact lenses like saline solution, daily cleaner, multipurpose solution and hydrogen peroxide solution.
Saline solution: When using an ultra violet disinfecting system, saline solution is used for rinsing and storing contact lenses. It is also used with enzymatic cleaning tablets or cleaning or disinfecting devices.
Daily cleaner: A few drops of daily cleaner is placed in the palm of the hand and each contact lens is rubbed for about 20 seconds to make sure both sides of the lens are clean.
