Contact lenses are thin discs that when they are on the cornea of the eye serve as a substitute for eyeglasses. The conditions that corrected by contact lenses are the same as the conditions corrected by eyeglasses and include the following:
• astigmatism (distorted vision)
• Myopia (nearsightedness)
• Hyperopia (farsightedness)
• Presbyopia (need Bifocal)
Just as no two sets of fingerprints are identical, no two pairs of eyes are exactly alike either. For this reason there are different types of lenses for different types of eyes. Read below to find out what type of contact lens is right for you. Hard lenses
If you are looking for the cheapest alternative in prescription lenses, you should consider PMMA lenses. These were the first contact ever developed, and although they are not the common choice among carriers who are still manufactured today. This type of contact lenses is known as a rigid and perhaps a bit harder on the eye. They consist of material more stable than other types of contact lenses. These lenses are made of PMMA, a type of plastic that is extremely durable. You are not aware that the most comfortable lenses on the market, but are very durable, and easier on the budget as more comfortable options. This is not the best option for people with sensitive or irritated eyes.
Hard lenses, breathe
Rigid gas-permeable contact lenses, also known as also known as “RGPs” are a slightly newer version of hard (rigid) lenses made of plastic and other materials, including silicone. An important factor in this type of lens – Fluoropolymers allow oxygen go right through the lens, making it “gas-permeable.” Some of the advantages of RGP’s are that they are better at keeping their shape, creating a crisper drawer vision, they keep the eye moist, and they resist the dust and dirt. This type of prescription contact lenses is ideal for:
• Those whose eyes are overly susceptible to bacteria and are susceptible to infections
• Those who are vulnerable to suffering from dry eyes
• LASIK surgery candidate
• People who participate in sports –
• Users of Bifocal glasses and reading glasses
Soft lenses
Soft contact lenses are made of thin plastic and water. The water component gives the lenses a soft consistency and flexibility. Soft contact lenses let oxygen through also, so that the eye to breathe. The majority of prescription contact lenses in the U.S. use soft contact lenses. Some of the reasons that are provided are: the fact that they are more for convenience, are easier than hard lenses to adapt to and can be worn for longer periods. Some of the soft lenses on the market include the following.
Extended wear lenses
Extended wear lenses are soft contact lenses made of materials designed to operate over a long period. This type of prescription lenses can be worn for 1-4 weeks without removal and cleaning. Although these types of lenses allow oxygen to penetrate and they tend to keep the eyes moist, they are probably not the best option for people with sensitivity and irritability.
Disposable Lenses
Disposable lenses are designed to be worn for a limited period and then discarded. This type of lens is ideal for people with sensitive or irritated eyes. Although it is usually more expensive than other types of lenses, the fact that they are replaced daily by a new pair she holds a very low risk of infection.

Everyone on this planet starts in the same way. One sperm cell fertilizes an egg. As each day passes, something new developed. Within two to three weeks to develop the eye and even after birth, eye and vision continues to develop and grow stronger. In fact, it is not until three years that a child is the same vision as adults. Eye Care is as important if not more than an adult.
At birth, the child’s eyes checked for any visual congenital defects of the eyes. The mother has a detailed family history looking for any possible genetic defects. If there is a possibility of a hereditary or birth defects, the pediatrician may recommend further tests to determine whether the baby is haunted. After the first eye exam, rigorous tests are usually recommended at six months, three years and then every year after five years. If the pediatrician notices any abnormalities regularly, he or she may recommend a visit to an ophthalmologist for Pediatric Cardiology. Diseases such as cataract and glaucoma are not isolated to only the elderly. Pediatric cataracts and how they occur and are a bit pediatricians and eye care professionals should be sought.
Most children have healthy, normal eyes, but a few are born with serious diseases or disorders of the eye, some of which may not be obvious.
* White pupil – may suggest cataract, tumor, inflammation, or retinal solve.
* Lump, swelling or hanging the lid – can be an inflammation, which is a state of emergency if it happens suddenly, and the lid is red and hot. Also may indicate muscle weakness or tumor causing blockage of vision.
* Large cornea – this may be a sign of glaucoma in both newborn and infant, especially if the child’s eyes water and avoids light.
* Eye turning inwards or outwards. Eye (s) incorrectly (rotated or not) or “lazy eye”. Eye turned in or out could lead to loss of vision.
* Dancing Eyes – Eyes jiggle or rotate; child is not able to see.
* Head tilted to one shoulder, to the front (chin down), or on one side. – Child can be avoided double or blurred vision.
* Part of the iris is missing. – Can the outward sign of a defect from the inside of the eye.
* Unequal pupils – a larger school. Can a sign of nerve damage or the tumor is visible in one eye.
If the child is of age at the beginning of the school, the teacher often notices when the child has problems with his vision. It might be a reluctance to try to read the blackboard or eyes to see printed words on a piece of paper. The teacher will then either the rule talks with parents about the problem or send a note home to discuss the need for an eye examination.
The actual eye exam may be different from that of an adult. If the child can not read, then forms to replace the more common letters. The test is a bit more difficult for the specialist because of the communication level. If a vision problem is detected, the eye doctor may or may not recommend glasses. Often a vision problem is age and the associated physician may choose to wait to see if the child is over. If glasses are prescribed.
The eyes and the vision is a valued asset. From the moment of birth, they are our window to the outside world. It is through them we know that color and brightness. A baby-eyes, and to absorb the outside world. Parents, teachers and doctors will monitor the child to ensure that the eyes and vision are working properly without errors. Eye exams are essential for all.
