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.

LASIK eye surgery is used to reshape the cornea in order to correct vision. The LASIK refractive eye surgery procedure can treat myopia (nearsightedness), hyperopia (farsightedness) and astigmatism, and can reduce your dependency on eye glasses and contact lenses. Patients who suffer from myopia, hyperopia and astigmatism experience blurred vision. LASIK eye surgery offers you an effective treatment to improve your eye’s focusing power and enhance your vision.

What Makes a Good Candidate for LASIK?

A good candidate for LASIK eye surgery should be at least eighteen years old, have no change in refraction for at least one year and have realistic goals and expectations regarding the results of the surgery. Anyone with an eye infection or injury within the previous year should forego LASIK eye surgery. Your eye surgeon or ophthalmologist is the best one to determine if you are a good candidate for this procedure after a thorough examination and consultation.

The Risks and Benefits of LASIK

LASIK eye surgery benefits include improved vision, and freedom from eye glasses and contact lenses. This freedom from eyewear means you can perform every day functions and even participate in sports, swim, spend a comfortable day on a sandy beach or go mountain climbing without the restrictions eye glasses and contact lenses impose on you. LASIK eye surgery is an effective and safe treatment experienced by millions of people. A small number of people, one to five percent, may experience LASIK complications. Risks of LASIK eye surgery may include:

• Sensitivity to light
• Haloed or glared vision
• Irregular astigmatism
• Dry eyes
• Loss of visual clarity

Recent advances in LASIK technology have dramatically reduced the risks of these complications and most problems can easily be rectified with additional treatment. LASIK eye surgery is typically nearly painless with most people complaining of only mild discomfort.

LASIK eye surgery is the most frequently performed vision surgery in the United States. Over one million people have LASIK eye surgery every year with excellent results. LASIK eye surgery is performed in less than fifteen minutes with most experiencing improved vision immediately.
