Dry Eyes

Dry EyesQUESTION

After wearing my contact lenses for a while, I have got the feeling that my eyes are becoming dry.

ANSWER

When one senses the unpleasant feeling of “dry eyes”, which leads to reduce the time lenses are worn and to increase the frequency of blinking (eyelid winking), we can reasonably think about different problems:

- real “ocular dryness” (or, as to say, insufficient tears). In order to correctly evaluate this problem, it is necessary a serious medical examination;

- the internal geometry of the lens (inner shape) is not suitable to the patient’s ocular situation. In this case, a visit to the authorized optician of the contact lenses is needed;

- the lens “interefe” with the natural mechanism that controls and stimulates the frequency of the blinking (eyelid winking) and the patient must be “taught” how to restore the normal frequency of the blinking. To this aim, specific exercises exist which the optician must adjust to each single patient.

Preliminary Tests For Contact Lenses

Test for contact lensesQUESTION

Why my contact lenses annoy me after only 3 hours?

ANSWER

Many problems which come up while wearing contact lenses stem from poor preliminary tests. And this is also why a Patient may experience annoyance after just 3 hours of wearing contact lenses. In fact, the purpose of these preliminary tests is to find out the best technical solution.
It is true that a period of “physiological adaptation” is necessary, but it is also true that such period (at least for soft lenses) should be more or less a week. Once this period is over (unless there are evident improvements), it is good that the Optician checks the whole technical aspect of the adaptation.

Accommodation of Contact Lenses

Accommodation of contact lensesQUESTION

We are frequently asked about the correct use and accommodation of contact lenses.

ANSWER

Here below are the legal and technical procedures to follow:

1. medical check-up, which is necessary to evaluate whether the patient is suitable to the use of contact lenses;

2. technical control (on behalf of the Optician), to decide which kind of lenses to choose;

3. technical assistance to the patient to teach him how to use and maintain his own contact lenses;

4. follows-up to make sure that the use of contact lenses is not causing damages or problems to the eyes.

This is the procedue highly recommended by all professional associations of both oculists and opticians. Sometimes, to shorten times, one or two steps are skipped and that is when problems come up which are “erroneously” attributed to contact lenses.

Sports Glasses: The New Genetyk

Friday, March 19th, 2010

Genetyk by Rudy Project is the result of a 25-year optical research aiming at protecting the eyes from sun rays and atmospheric agents, thus helping the wearer to concentrate during sports performances. Among the winning features of this model, which well adapt to competitions and has been thought to reach the best positions, an enveloping mask-shape and up-to-date technology, also as far lenses are concerned. In fact, Genetyk is available in a wide range of hig-tech lenses, such as the ImpactX Photocromic Clear ones, highly resistant and available in many different colors, hence perfect for those sports where competition can last for many hours (e.g cycling); the Polar3FX, which reduces water reflection and so are ideal for watersports; and the Golf100 ones, studied to improve the perception on green. All lenses are interchangable thanks to the patented system “Quick Change”.

The Dangers of UV Rays at Mountain

Sunday, February 7th, 2010

According to a research study carried out by Ipsos Health for Transitions Optical, the American company leader in the field of photocromic lenses, Italian people are totally uninformed about the possible consequences of exposure to sun rays and about 20% of them think that sunglasses are harmful to the eyes! But opticians well know that what is harmful to the eyes is something else, like neglecting to protect the eyes and their outiline at mountain also during gray and cloudy days. UV radiations, in fact, are always present and 80% of rays succeed in passing through the clouds.
Besides, snow is able to reflect 80% of sun rays, unlike grass, which reflects just 10%. Every 100 meters in height the UV rays undergo an intensity increase of 6% to 8% and, at high altitudes, even of 12%. It is useful to remind that a Ultraviolet excess can cause damages to the crystalline, which become more and more serious as one gets older.

Eyesight is a Precious Asset 2-2

Thursday, January 28th, 2010

A neglected problem: eye fatigue
More than 1/3 of Italians (37%) answer that their eyes often get tired, while only 27% state that they have never had problems on this account.
Despite this, only 9% has considered specific protective lenses. The criteria when choosing eyewear seem to be above all “lightness” and “design” (respectively 26% and 24%). The general impression we receive is that eye fatigue is not considered a pathological problem, but more a natural phenomenon which is dealt with generically by resting.
Poorly informed consumers
On the subject of lenses, however, 26% do not know what lenses their eyewear have, 23% are aware of AR coatings, 10% of the fact that lenses may be plastic and only 6% know about photochromic lenses.
When separating men and women, lens lightness is important for both, while AR seems more important for men, and infrangibility for women. Lightness is however the most determining objective feature for overall choice of eyewear (frame + lens) and is underlined by 26% of interviewees; the advice of experts -ophthalmologists (39%) or optician/optometrists (26%) is also important. The other criteria guiding choice are design (24%), which counts more than price (19%), while infrangibility is down to 13%.
Fashion as a reason for purchase
Fashion seems to be an impetus mainly guiding the choice of a frame but not that of eyewear as a whole. There is therefore a need to constantly inform consumers and also sensitize them on aspects more connected to eye protection and health, such as the adoption of suitable lenses to individual needs and lifestyles.
Little is done to protect children
As far as children are concerned, most parents (66%) state that they protect their children’s eyes (49% in the 5-8 age group; 52% in the 9-13 age group). Lastly, 17% of parents do not adopt any measures to protect the eyesight of their children. In reality, it seems that as long as they are young -i.e. more or less until they are 13 – the best protection against UVA rays is a hat!
More information, more education to prevention and protection
As already emerged in Phase 1, the research study carried out by IPSOS for Transitions Optical highlighted a fairly superficial attention by the Italian public to problems linked to eyesight, an inadequate adoption of measures to protect it and, even more, an endemic lack of information and “culture of visual wellbeing”.
This sounds like a pressing invitation to the industry, trade association and eye specialists – oculists and optician-optometrists first of all – to strengthen their commitment toward greater information, sensitization and education of the public on such crucial issues for the lives of all.

Eyesight is a Precious Asset 1-2

Monday, January 18th, 2010

Eyesight is an inestimable, precious asset. And yet, Italians do not seem to be aware of it and, above all, be particularly careful about protecting their eyes. Transitions Optical made a research interviewing 1000 persons on the phone.
In Italy there has been a growing awareness of the importance of health and physical fitness to ensure a high quality of life. This trend does not seem to have involved the eyes and sight, as it is demonstrated by a research study carried out by IPSOS Health for Transitions Optical, a world leader in photochromic lenses. The international study, conducted in successive phases, each of which dealing with specific themes, at this stage involved four European Countries: Germany, Italy, Portugal and Spain.
In Italy the results show that around 48% of the population, i.e. 5 Italians in 10, wears spectacles or contact lenses, an important datum although 41% of the interviewees state that they have no problems with eyesight. Those who mention them place myopia in first place (31%), followed by astigmatism (14%) and, in third place, presbyopia (9%). The first part of the research (published in May 2007) also revealed the lack of concern for the effect of solar rays on the eyes. Consequently, the study underlined that as many as 16% of the interviewees do not use any protection or aid to protect their eyes during exposure to the sun. Moreover, a worrying 37% had expressed the erroneous conviction that damage to the eyes is reversible.
Let’s concentrate on the second stage of the study, made public last October.
Eyesight protection is in third place. Only 39% of Italians (36% men and 42% women) consider that maintaining the efficiency of their eyesight is considered halfway between the very important and the unimportant ones, thus revealing a worrying situation of lack of information and sensitivity to the problem.
There is a surprising persistence of certain prejudices concerning eyesight in the minds of the Italians. For example, 7 Italians out of 10 are ignorant of the fact that as much as 80% of the quantities of UVA rays we are exposed to during our lives takes place before the age of 18, or as many as 62% of Italians consider that people with dark eyes have fewer problems regarding exposure to sunlight! Just out of curiosity, we may add that 20% of Italians think that sunglasses may “damage” the eyes, a fact that probably has to do with many low-cost products, without warranty brands, purchased in the street, on stalls or the beach.

Sensitive to Light

Saturday, December 19th, 2009

Younger Optics Europe presents the high-technology photochromatic lenses for drivers, studied to elaborate visual information at the best in variable light conditions.
The photochromatic technology used for Drivewear lenses derives from the union between the transitions experience and the NuPolar technology by Younger Optics.
Ideal for drivers, the new lenses are the perfect synthesis between polarization and photochromism, a combination of advanced technologies which well adapt to any light condition.
When the sky is cloudy, only the yellow/green polarizing filter works, which enhances the contrast and blocks out reflections.
On the contrary, in presence of sunlight, while the windscreen blocks out the UV rays, the photochromic molecules are activated by the intense light region of the solar spectrum.
As a consequence, the lens turns into a brownish colour and the light absorption increases, ensuring the driver a good visual comfort.
Finally, when the sunlight is really high, the Transitions photochromic molecules are completely activated and can totally block out the UV rays, while Drivewear lenses become quite dark.
This product, which was patented as original invention, represents a real innovation because not only it reacts to UV rays, but it acts at the best also through the windscreen filters, allowing the driver to well recognize the colors of the road signs.

Many Dangers to the Eyes 2-2

Monday, December 14th, 2009

For many years, prevention has been the main focus of lenses and frames manufacturers, but today new alarms are drawing ophthalmologists’ attention, in particular with reference to sunbeds, coffee and cigarettes. According to Francesco Loperfido, responsible for the General Ophthalmology Center at the San Raffaele hospital in Milan, “a long exposure to sunbeds’ rays may cause harm to both skin and the eyes”. The injuries which can be caused to the eyes by a long exposure include keraconjunctivitis and, in the most sever cases, the opacity of the crystalline lens. Besides, SOI experts reminded that smoke may put sight at risk and the disease is called alcoholic neuritis -as Antonio Mocellin, SOI vice-president, explained. Alcohol and smoke, but also too much caffeine, may cause an ocular intoxication. Caffeine and nicotine, in fact, restrict the veins and, in the end, produce damages to the optic nerve; as a consequence, eyesight is reduced and a visual field deficit appears which, if neglected, can lead to very severe injuries. In addition to the usual "enemies", new factors must now be taken into account, due to the many and continuous changes in lifestyle. Those who work outdoor, for example, are more exposed to this kind of risks: masons, refuse-collectors, fishers, or even postmen. A market section could develop within the optic field, similar to those already present in other product categories, like clothing, shoes, gloves, etc. In conclusion, many are the dangers to which the eyes are exposed. It is the experts’ duty to inform and help to prevent the patient’s eyes from severe damages.

Many Dangers to the Eyes 1-2

Wednesday, December 9th, 2009

Although UV rays are known as the “long-term enemy” of the sight, today more and more attention is focused on blue light, particularly harmful to minors and people over the age of 55. A study from Cnr Biometereology Institute, carried out by the Sight Defense Commission and shown in Milan, revealed blue light’s dangerousness: its wave length, indeed, falls within the visible range, but near UV (400-500mm). In this case, the damage is not direct: the eye is very rich in oxygen and all the parts that make it up are sensitive to oxydative stress and, if hit by light, produce several free radicals that, over the years, cause a progressive damage. To protect one’s eyes from ultraviolet rays and blue light since childhood is pivotal. Unfortunately, still today many parents underestimate the problem and buy low-quality products. Instead, the purchase of a good product is the starting point of a correct prevention in general, both for children and for adults. The optician will be glad to help anyone, irrespective of age, to find the most suitable frame.
