Close to your eyes

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.

Some Side Effects of Wearing Contact Lens are to the Disappointment of Users

The buildup of intraocular fluid on contact lenses is a possible side effect to the eyes. Lenses with such deposits are uncomfortable to wear. Users of these lenses are at risk of an eye infection. Soft contact lenses are prone to developing deposits of intraocular fluid more than hard contact lenses.

Such problems as swelling of the eyes and vision haziness that are associated with the cornea, off and on result from the use of contact lens. Lenses barricade the flow of oxygen to the corneas resulting in a condition called hypoxia. Users can suffer scrapes and scratches from lenses to their corneas. Bacterial Keratitis is a corneal infection that can result from the all time use of both soft and hard contact lenses.

Persons using lenses most of the time may suffer from inflammation of the eyelids. In some cases, inflammatory bumps appear under the eyelids. They are small but painful. Persons affected with eyelid inflammation have a painful experience of wearing contact lenses.

Developing dry eyes is one of the most common side effects that contact lens is known to have. Lenses absorb a little of fluid from the surface of the eyes and as a result, leave them dry. Users of both soft and hard contact lenses are similarly prone to having dry eyes. Severe symptoms like itching or burning sensation, redness, excessive tearing and swelling surface in case of persons with dry eyes.

People who wear lenses may also experience a kind of allergic reaction. Turning of the eyes red when lenses are inserted is a common allergic reaction. Such an allergic reaction subjects the eyes to hypersensitivity that results from the preservative used in contact lens solutions. Solutions with a different preservative are prescribed for persons with allergic reaction from lenses.
