According to different eye conditions such as light sensitivity, it takes varying periods to adjust to contact lenses. In general, rigid gas permeable contacts require more time for adaption than soft ones. Most contacts in different materials need daily care, while daily disposable contact lenses and some extended wear contacts can be discarded on removal.

Currently, gas permeable contact lenses are also available in high-index materials, which have long been used only for eyeglass lenses. Using high-index materials, Paragon Vision Sciences published its HDS HI 1.54 GP lenses, which are more comfortable and allow more oxygen to reach the cornea. People with heavy prescription can benefit more from this new lens design, because contacts made of high-index materials are thinner than conventional GP lenses.

Most of the patients who received laser vision correction surgeries such as LASIK and PRK get a perfect vision recovery. However, a small portion of patients may suffer from glare, halos and starbursts as well as irregular astigmatism after these surgeries, due to the different ways that the patients’ corneas respond to laser energy. Their daily life quality may further be deteriorated by side effects such as eyestrain, headache. What’s worse, a second surgery for enhancement may be impossible. In this case, GP lenses or hybrid contacts are the solutions for sharper vision.

Currently, contact lenses are provided by various sources, because prescription has been an independent medical service. With your prescription, customers can buy contacts from ECPs, optical stores, warehouse clubs, and online stores and so on. The overall value of lens deserves the top consideration, which includes availability, customer service, convenience, bundled products, professional services and price.

GP lenses have a disadvantage that they may cause eye irritation, after a gust of wind containing dust and other airborne materials. In fact, GP lenses are smaller than the cornea and float on the tears. In contrast, soft lenses cover more part of the cornea and are less likely to cause this problem. Some contact wearers need a plunger to remove their lenses, although the most convenient way is to use fingers.

For convenience and a wider filed of view, more and more people choose contact lenses instead of eyeglasses. The 2007 Contact Lenses in Pediatrics (CLIP) study showed that 169 teenagers and children age 8 to 12 who have worn contacts for three months felt more confident and performed activities better than before. During sports, they don’t have to worry about glasses’ getting knocked off or fogging up. Though contacts are getting more and more popular, there are still lots of things you should be aware.

A competent eye care practitioner is critical to offer proper lens fitting. Some contact lenses wearers worry about the appropriate position of their lenses. In fact, wearers should only put their lenses straight on the cornea. And well-fitted lenses will always stay in the right position as the eyes move. A cheapskate may want to re-use contact lenses that were prescribed months or even years ago. This is very dangerous because during the period bacteria may grow. A new pair is needed.

Toric contact lenses for astigmatism correction are available from various brands, with specific materials, designs and features. In general, toric lenses are designed to maintain stable on the cornea. However, a small portion of toric lens wearers may experience lens rotation, which is surely to affect vision quality. In this case, these individuals should see a contact lens specialist to search out the underlying cause.

Although there is high success rate, refractive surgeries including LASIK are not perfect. Postoperative visual problems may affect overall correction outcomes. In fact, the way in which the shaped cornea responds to laser energy and the healing process all play their roles in final surgical results. Potential bothersome problems caused by unsatisfied vision correction include blurred or distorted vision, irregular astigmatism, eyestrain and even headaches. In these cases, gas permeable or hybrid contact lenses are needed.

A recent study involving children age 8 to 17 shows that more than half of these children are interested in contact lenses, a third of whose parents are not reluctant to consider contacts for their kids. There are also 40% of children who dislike wearing noticeable eyeglasses. Parents’ concerns are associated with lens care. Eyeglasses are easier for daily care but contact lenses require more complex lens care. Those parents think that their kids are too young to take good care of contact lenses. In fact, there are other researches reporting that most children are capable of caring for soft contact lenses.
