Total Articles: 10
A market research survey pertaining to eye problems revealed that among children with ages from eight to 17 years, over ½ expressed their intentions to wear contact lenses. The other 40 percent showed their dislike for the usual eyeglasses. Meanwhile, one-third of parents are willing to allow their children to use these eye devices. Most of the adults concerns were associated with caring for this type of lens.
It is true that maintenance of eyeglasses is much easier as against contacts which call for more complex procedures and disinfectants. Contact lenses are more liked by younger individuals in many aspects. Children, who have worn contacts in the past, obtained higher self-interest in physical appearance, athletic prowess, academic performance, social acceptance and overall self-esteem. Some children who have opted to use contact lenses also show more confidence in their academic tasks.
The use of prescription eyeglasses may have brought a decrease in their self confidence. Find out the various categories of contact lenses such as PureVision contacts in the market. In fact, some lenses are believed to have the capacity of curing eye disorders other than poor vision. Therefore, it is vital to understand the benefit and drawbacks of these contemporary tools. The modern contacts are made of soft lenses produced from water-containing plastics and gas permeable non-flexible varieties.
What are contact lenses made of? These are fabricated from a hard plastic material which is also the same plastic material used to make translucent acrylic plastic. However, hard lenses do not have the capacity to absorb water required to help oxygen pass through the lens and into the cornea. Hard lenses can cause the wearer a lot of tenderness and discomfort since the eye needs oxygen to stay healthy. The positive aspect of these lenses is the efficacy of cleaning since these are not easily affected by bacteria.
You can order cheap contact lenses online. Yet, there are certain things to consider before making any purchase. If you have used these eye implements before, it is practical to order the first set from an ophthalmologist. It may be more expensive than online means. Nonetheless, you can ask a professional to teach you how to put these on, make sure about the fit and show you how to take care of the lenses. If you have been using contacts before, you have to get the same variety of devices online. Allocate sufficient time in comparing brands, features, benefits and prices.
Soft contact lenses are more elastic and easier to wear than hard lenses. These are made of soft, plastic which are hydrophilic and capable of absorbing water. Oxygen can be transferred to the eye making the lens adaptable and more comfortable to wear. When a large volume of oxygen reaches the eye, this indicates that you can wear soft contact lenses longer with less chance of irritation. Although contact lenses are fairly safe, these can still lead to minor issues like discomfort, rosiness or tearing. In certain conditions, extended-wear lenses can cause infections like corneal ulcer which can lead to permanent vision damage.
