Contact Lens And Their Effects
Irritation may occur as a result of worn-out lenses, over-wear of lenses, poor care of lenses, intolerance to solutions, or infections. Irritation may also occur from poor hygiene on the part of the lens wearer.
If worn longer than recommended or in people whose eyes are particularly sensitive, lenses may develop deposits on the surface of the lenses and cause irritation.
A major cause of blinding eye infections is spitting on a contact lens or putting the lens in one’s mouth when no solution is available. This happens when a contact lens wearer must remove a lens or if a lens falls out of the eye and no solution is available. The best prevention is to have a small bottle of rewetting solution with you at all times. Never, never put your contact lenses in your mouth to lubricate them.

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.
Facts About Contact Lens Saline Solution
When it comes to contact lenses, the saline solution is as essential as the lens it self. The saline solution is the liquid substance used in rinsing and moistening the contact lenses to prepare it for use. You should never use your contact lenses without disinfecting it first.
The solution is also helpful in removing small elements and debris from the lens’s surface. This function is very important because it assures you that there will be no irritants that can cause infection to your eyes. Also, saline solutions are used to maintain water balance, especially to the softer types of contact lenses.
There are three basic kinds of saline solution. These are the commercial solutions with preservatives, the commercial solutions without preservatives, and the homemade solutions that also do not have preservatives at all.
Some contact lens saline solutions use preservatives to aid in slowing the propagation of bacteria in the lens. The saline solutions, especially the ones with preservatives, should be used according to the guidelines that come along with it.
Contact Lens Types
Soft contact lenses have been released in many different formats since they were first developed in the 1960s.
Soft contact lenses were originally designed to be worn for 12 to 18 months and removed nightly. These contact lenses are now called “conventional soft contact lenses”. They are usually prescribed as a specialty lens and are generally used when frequent replacement or disposable contact lenses are not available. They have the disadvantage of being more expensive and tend to accumulate surface deposits. This mode of lens wear requires more diligence with cleaning and care.
Disposable contact lenses were first released commercially in the 1980s. The first disposable lens was the Johnson and Johnson Acuvue contact lens, which was a 2 week disposable contact lens. It was a soft hydrogel lens and was primarily worn on a daily basis. The original Acuve contact lenses has only recently been discontinued. It was designed to be replaced after 2 weeks of daily wear.
