Shortsightedness: let's spend 3 hours in open air 12 October, 2015 - Comments (0)

Villa in Ariano Irpino

Shortsightedness, by now , it is spreading more and more in almost all the countries in the world, reaching, in some of them, very high peaks, so that researchers have to deal this worrying problem.

Shortsightedness diffusion rate reached 90% values in teenagers and young adults from China, Singapore, Hong Kong and Taiwan. It is not better in west, in fact in USA shortsightednesspredominance has gone from 25% to 40% in last 20 years, and in Europe this is following the same growth trend. Which are the causes of this event, and how can we retain it?

As it is commonly known, the shortsighted eye’s difficulty is in vision from far away , to the detriment of a good vision from close distance. This refractive defect is caused by the major length of the eye, whereby the images are being developed before retina, causing out of focus vision from far distance.

The progressive increase of shortsightedness prevalence, induced the scientific research to study the event and in few years the researchers have understood the causes. The studies have been about the various correction methods (glasses with bifocal or progressive lenses, contact lenses, and medicines).

To spend more time in open air during the childhood protects eyes against shortsightedness, as shown by the working equipe of Donald Mutti at Optomerty College from Ohio State University in 2007 and by Kathryn Rose from University of Sidney, the following year. Even if processes aren’t still so clear, this protective effect is due to simple sun exposure that encourages the dopamine release, slowing the ocular bulb growth.

Deeper studies carried out in China, Australia and Taiwan in the schools where daily activities at open air were introduced during school time, showed that kids who spend more time in open air, are protected against occurrence of shortsightedness.

From theory to practise, the passage is tough. The first attempts made inAustralia, came out to be a sort of failure because families cannot handle in an adequate way the time to be spent at open air. To solve the problem, the matter could be given to schools, that would introduce in their programs the activities to be done in open air, to alternate to those done in closed spaces.

This solution will bring many benefits, starting from the physical activities incentive, to body reinforcement, to reduction of children obesity.

Blue eyes and alcoholism 11 October, 2015 - Comments (0)

According to the result of an American survey, people with bright eyes has 54% of chances more, to suffer from alchool addiction, with respect to those who have dark eyes. For those who have blue eyes, the percentage is up to 80%. The cause is a correspndance between the genes that regulate the colour and thos ethat influence the addictions.

Blue eyes have always been an inspirating source for artists. But, as we already know, people with blue eyes have not an easy life: blue iris ( and grey) is more delicate and more predisposed to uveal melanoma.

According to a survey made by american researchers from Vermont University, published on specialized magazine American Journal of Medical Genetics, blue eyes and alcoholism, that apparently are poles apart, would really be linked. The survey involved 1263 volunteers of european origin, 992 of them with alcoholism diagnosis .By studying the incidence of this pathology, it came out that people with bright eyes have experienced an alcoholism rate of 54% more tahn people with dark eyes, with a peak of 80% for subjects with blue eyes.

The cause should be due to a correspondance between the genes that regulate the colours and those that influence the addictions. The test has been repeated fr three times more, to net of factors as age, geographical origin and sex: the result is always been the same. According to american researchers, there will be still needed further studies to make a deeper study, but, if the result will be confirmed, eyes colour could be inserted within the predictive factors for alcoholism diagnosis.

For every child, the first pair of glasses represent a great challenge; glasses, in fact compromise every day life and, they alter the image that the kid has of himself.

To wear glasses, creates discomfort both in older kids than in younger ; for this reason parents have to explain the motivation of this great change.It is necessary to reassure the baby of the fact that his new way of appearing does not change for any reason the love and affection that they feel for him. Up to seven years of age , infact , the discomfort of the child is limited to the relationship with his image , but glasses are not frowned up, on the contrary, if the defect is so "important" the child himself will require the glasses when he will be in need.

For older children, the problm is more complex, considered that they percevie their image in a way that is different from those of their contemporary in age, abive all if schoolmates make fun of him. After xis years, it starts the most difficult phase for the child, in fact for him it's mportant also the opinion of others, not only those of his parents.

It is important to not impose glasses for children, but to let them be gradually accostumated and, above all, it is necessary to be coherent and determined in letting them understand the importance of glasses

If parents already wear glases, the work can be easier, considered that children have the instinct of imitation of older people.

It is possible to convince the child, that glasses will aloow him a better vision of his favourite cartoon, and, he will not have to wea them forever, but only for a certain perido of time.

Compatibly wiht optical and medical necessities, the child has to choose the frame he likes more, or the frame with whch e is similar to his favourite tv character.

Obviously there will be difficult moments, when the child willrefuse the glasses. He could loose them, forget to wear them, or keep them away at first occasion. Those moments last few weeks, after that the results of your work will be chown.
