Considering the growing popularity of different contact lens types among children and teenagers as well as the increasing problem of myopia in these age groups, it is worrying that the number of eye exams performed in individuals under 15 has reached a decade low.
According to data provided by the Health & Social Care Information Centre, the percentage of children under the age of 15 undergoing eye tests has fallen from 24 to 19%, though the total number of NHS-financed eye tests performed in the country increased from a little under 10 million to over 12 million.
Eye tests have turned out to be the most common among patients over 60 years old, 44% of whom visited optometrists and other eye care practitioners.
Interestingly, over the last ten years, the number of optometrists has risen by about 30%, which means eye tests are much more easily available.
The low number of children undergoing eye examinations can be a serious problems, because many of them could have uncorrected refractive errors and other eye conditions that require treatment. What is more, those who already wear contact lenses or glasses should be examined even more often others, because short-sightedness in children tends to progress quite fast.

The choice between glasses and contact lenses is not easy for some patients, so experts from the Tribeca Vision Centre decided to help them, and published an article with the most useful information on the subject.
There are numerous differences between these two methods of vision correction, and both of them have their own unique advantages and disadvantages. Contact lenses, the experts emphasise in their article, feel natural, because they are difficult to notice and do not create a barrier between their wearers and the rest of the world. They do not fog up in the winter and do not cause problems when you play sports. Plus, of course, they are much more convenient when we deal with our daily tasks. You can also mention coloured contact lenses which also serve as a beauty enhancer.
Glasses, on the other hand, are a cheaper option (one pair can be used for years provided your refractive error does not change). They are also considered to be safer and easier to maintain (most contact lenses have to be cleaned with special lens care solutions).
However, at the end of the day, the patient needs to find out if he or she can put something in his or her eyes, which is a prospect that is scary to many of us. This is the ultimate test, which – as millions of people around the world have already found out – is really worth passing.

Baseball is a sport that requires a number of different skills and qualities. Considering the fact that a baseball pitched by a professional player can move at speeds exceeding 150 km/h, it comes as no surprise that players need to have the ability to focus and their eyesight needs to be extremely good.
According to Mark Schiffer, a baseball expert writing for Stack.com, the batter needs to see the ball and the way it moves as quickly as possible. Without perfect vision, it is impossible to achieve the level of professional baseball players, Schiffer added. Those who suffer from myopia must wear contact lenses (glasses are impractical and cannot provide the same quality of vision as contact lenses) or undergo laser surgery.
Traditional contact lenses are the most popular option, but some players decide to try tinted lenses designed specially to improve their performance by enhancing contrast and protecting them against the impact of sunshine.
Of course, great eyesight is not enough to become an excellent baseball player, but without it, it is simply impossible, Schiffer concluded.

Two patients who decided to take part in a special promotion and try Bausch and Lomb's Biotrue ONEday contact lenses have won a four-day trip to Barcelona.
Emma Davies and Oliver Rohan could not believe their luck when they heard they would spend four whole days in the beautiful Spanish city. Ms Davies decided to try the contact lenses after her optician recommended them to her. She found them very comfortable and was really satisfied with the quality of vision they provided. Mr Rohan, on the other hand, was attracted by the possibility of winning the trip to Barcelona, particularly because it included a chance to fly in a hot-air balloon. He had always wanted to do that, but never had the opportunity.
According to Bausch + Lomb's regional sales manager for North UK and Ireland, Tom Bailey, the company is really happy with the response to the promotion and it is planning another one, but its details will be revealed later.

One of the most important (though not the most common) applications of contact lenses is improving the state of the cornea after ocular surgery. Recently, a group of researchers have evaluated the effects of using two brands of continuous wear contact lenses as bandage lenses after photorefractive keratectomy.
The study included 47 short-sighted patients who had undergone photorefractive keratectomy. Each of them was fitted with Ciba Vision's Lotrafilcon B and Menicon's Asmofilcon A contact lenses; they were asked to wear one of the lenses in each eye until full re-epithelialisation was achieved. Detailed examinations were carried out on the day of their operations as well as on the first four days afterwards.
The examinations revealed that 87% of the eyes fitted with Asmofilcon A contact lenses were healed after three days. The proportion was slightly lower (74.5%) in the eyes fitted with Lotrafilcon B contacts. The researchers concluded that both brands of silicone hydrogel contact lenses were very effective bandage lenses, as they facilitated the process of re-epithelialisation of the cornea. Asmofilcon A contact lenses are more efficient, the authors of the study suggest, but the difference may not be felt by all patients.
