Transitions - Visual Health First of All 1-3

Thursday, August 27th, 2009

Photochromatic transitions lenses for your eyes' healthThe company, whose photochromatic lenses are among the most recommended in the world, after the new successful campaign, launches the personal training for the eyes’ fitness

Visual health as improvement of the general and daily quality of the vision and long-term maintenance of ocular health to see clearly today and in the future: this is the priority and aim of Transitions Optical even for the next years, in which once again the end-consumer’s needs will be of the highest importance, an end-consumer we try to supply with high-quality products whose main features are comfort and clearness. The importance which is attributed to the culture of visual health by the company –whose official headquarters are located in Pinellas Park (USA)– is highlighted by Roberto Bellavita, Italy Country Manager, who highlights even Transitions Optical decision of focussing on the communication to the end-consumer by offering him all the necessary tools to choose with awareness.

Communication and visual health become then the foundations of the “made in Transitions” strategy, as it is confirmed not only by the “Live Your Vision” campaign and an international photography competition in collaboration with the National Geographic, but also by the launching of the first “Training for visual health”. The complete training for the eyes which has been thought by the company is made up of 4 programs - “Eyecare”, “Ocular Gymnastics”, “Yoga for the eyes”,and “Eye Treatments” - which have been studied to train, relax and take care of one’s own eyes.

Visual Performance in Sports Activities 13/14

Monday, August 24th, 2009

Sports Activity and Vision

The last group is made up of those factors which are related to the game peculiarities influencing the motor skills to activate:

-the duration of the competition and the presence of breaks vary among different sports and obviously determine how long the athlete must keep the visual performance;

-the mental or physical stress which the athlete endures may have an effect on the performance. Stress, indeed, may act on the incoming visual information, by intensifying the restriction on perception. This evidence has lead the vision-care experts to consider stress as a condition in which visual abilities are highly activated;

-the degrees of predictability and stability of the environment in which the sport is performed influence the motor skill which is required (Schmidt e Wrisberg, 2006) and the most relevant visual abilities. An exchange in tennis and a counter-attack in a football match are two examples in which an open skill is required, because the opponent’s possible “movements” are unforeseeable.
Athletics’ 100 meters, swimming 100 meters freestyle, a dive from the diving-board or an exercise of physical training at the parallel bars, are all conditions in which the environment is stable and foreseeable and the skill required is closed. Open skills need a higher ability to adapt all of a sudden, hence dynamic visual skills and a fast elaboration of the information.

Safer Driving with the New Photochromatic Polarised Lenses 2/2

Thursday, August 20th, 2009

“Activated by Transitions” means that these lenses have been carried out by applying photochromism –which is the change in colour according to the quantity of light present– in a new way:
in poor light conditions (for example, when the sky is cloudy), the lenses show a green-yellow hue, which favours contrast definition, highly reduces reflection and empowers the “useful light information” reaching the eyes.
In presence of high sunlight, which goes even through the windscreen, the lenses turn into a copper tone. This colour, which for many drivers is the most comfortable while driving, reduces reflection and brightness, improves the outline definition and the distinctness of red and green road signs.
Finally, when the driver gets out of the vehicle and looks directly at the sun, the lenses darken further until becoming dark brown and filtrating the extra-light as to guarantee comfort and visual wellness.
It must be noticed that brown helps to recognise the colours –in particular, green, which is the most recurring colour within the natural environment. These technological innovations must be added to the “consolidated” advantages of Transitions photochromatic lenses, which even in the traditional version block 100% of UVA and UVB rays, protect from reflection and reduce eyestrain.

Safer Driving with the New Photochromatic Polarised Lenses 1/2

Friday, August 14th, 2009

Safe Driving
From Transitions study, the lenses which adapt to every light condition and darken behind the windscreen.

Being able to drive in maximum safety conditions is the first need of everyone who daily face the city traffic on their cars. Advanced technology vehicles, safety belts and stricter rules for drivers have represented great improvements, but the real protagonist remains the driver, who must rely not only on his ability, but also on the supports that make driving easier.
In order to offer new safety standards to millions of drivers who wear prescription glasses (in Italy, 48% of the population) “Drivewear activated by Transitions” are now available, the first photochromatic-polarized lenses which adapt to light conditions and darken even behind the windscreen, solving the problems of dazzling light and low visibility.
Properly thought for drivers, compatible with every sight defect and adaptable to every frame, this type of lenses combines photochromism -the automatic darkening according to the quantity of light present - to polarization, which protects from blinding reflection. Studied to empower the human eye’s natural ability to adapt to different light conditions, these lenses derive from a cooperative project between Transitions Optical, world leader in photochromatic lenses, and Younger Optics, leader in corrective polarized lenses.

Visual Performance in Sports Activity 12/14

Saturday, August 8th, 2009

The third set includes those factors which can affect the visual performance and which are related to the environment where the sport is performed:

-the level of contrast which is available in the environment is extremely important. The perception of humps and dips in a low-contrast condition is highly reduced. Hence the contrast depends on light conditions. The sensitivity to contrast can be influenced by a person’s outfit and becomes critical for small objects moving fast. The possibility to operate on the athletes’ level of contrast through selective filters has gained a lot of attention in the vision care field (for a review, see Erickson, 2007);

-the prolonged exposure to UV rays can be a problem to sportspeople for ocular protection reasons. Obviously, the exposure is greater in outdoor sports, especially in high-altitude ones or when in presence of a huge reflective surface (not only snow sports but also nautical ones).
The problem is solved by using filters and lenses with UV-block systems.

Contact Lenses Maintenance

Sunday, August 2nd, 2009

Contact LensesTHE PRODUCTS FOR THE MAINTENANCE OF CONTACT LENSES ARE DIFFERENT FROM ONE ANOTHER!

A few days ago, a young patient we have been dealing with for several years came to us for the application of RGP contact lenses as keratoconus treatment.
Unfortunately, ectasia has had a progressive character over the last years and different types of lenses have had to be replaced to meet the parameters. The patient lives far from our office and comes to us just for scheduled examinations every six months, except for urgent matters coming up. A week before the last examination, our patient had noticed a decrease in vision and a discomfort whenever he would wear lenses. The lenses he was wearing had been replaced four months before and this new condition made us suspect a further keratoconus aggravation.
When the patient comes, he has not been wearing lenses for some days. We examine the eye refraction, the corneal topography and the cornea through a slit lamp, then reassure our patient about the fixed corneal condition. When inspecting the contact lenses, instead, a layer of superficial heaps is found out.
So, we clean the lenses with professional tools and succeed in giving it new birth without having to replace it with a new one. Fortunately, after this processing the patient can see well with his lenses and tolerate them again without any discomforts. A little stunned by this new condition of the lenses, we ask the patient whether he changed anything in the lenses cleaning and disinfecting procedure we had recommended.
The patient confessed that lately the optician’s where he usually buys maintenance liquids changed his supplier and invited him to replace the products we recommended with a unique liquid solution of the brand he had recently joined up. And this was the result. Besides the temporary discomfort, the usage of inappropriate maintenance put the patient at risk of an intolerance to contact lenses, the only optical support able to allow him a proper correction. This case leads us to reflect about the risks connected to a change in the maintenance regime of contact lenses we don’t know, especially if the patient is new and we know little about his clinique history.
We think that the maintenance of contact lenses should be worth a greater attention, the products should be selected from case to case, keeping always in mind that each liquid is different from the others. We don’t want to pass judgement on a product or another, but only bring more attention to the fact that different maintenance systems have different features.
