Were you born in the summer? You could develop myopia



Born in the summer and Computer lessons are connected with a higher risk of short-term or near-vision short-sightedness (myopia) in childhood, points to a twin study, published in the Digital Journal of the British Journal of Ophthalmology. But fertility treatment can be protective, evidence of discovery.

Lack is defined as a refractive error which means that the eye can not properly focus on the light, making the objects closer clear, but distant objects become blurred. It can be corrected by goggles, laser surgery or contact lenses, but the condition is associated with a greater risk of visual impairment and loss of vision in later life.

And the disease is becoming more and more popular: It is likely that 4,758 million people in the world will be affected in 2050 compared to 1950 million in 2010. Genes are thought to play a role in the disorder, but they do not fully explain the increasing prevalence. And, in view of the rapid development of eyes in early life, researchers wanted to explore possible environmental factors throughout their lives.

These experts studied the twins in 1991, whose average age was 16.7 years. The two twins were from 1994 to 1996 in the United Kingdom, and participated in the Long Term Twins Early Development Study (TEDS).

Opticians provided information on eye examinations for short-sightedness and the researchers analyzed the two-part demographic, social, economic, educational and behavioral factors when these children were 2, 3, 4, 7, 8, 10, 12, 14 and 16 years to perceive critical stages of development of children and eyes.

Parents and teachers completed exhaustive questionnaires, and twins conducted online assessments to provide a wide range of potentially relevant information and information on factors that could affect early childhood development.

The average age at which children with short-sightedness began to wear glasses to correct their condition were 11 years old. About one in 20 (5.4 percent) had "lazy eyes" (amblyopia), and a similar proportion (almost 4.5 percent) was strabismus. In general, one in four (26 percent) of the twins was short-sighted.

Factors that were most difficult to develop in the course of short-term development at different times were the achievement of parenting (university or postgraduate) education, computer games and birthdays in the summer. The number of hours played by computer moms may be due not only to closed work, but also with less outdoor time, a factor previously associated with an increased risk of myopia.

The level of education is related to myopia as well begins in the summer months of a child born in the UK Schools younger than those born in the winter months, scientists say that this close job can speed up eye enlargement, which is responsible for short-sightedness.


Levels higher household income and intelligence measurements, In particular, verbal skills were associated with higher risk, but to a lesser extent. Fertility treatment seemed to offer protection against short-sightedness and was associated with a 25-30 percent lower risk.

Researchers at London's Royal College of Ophthalmology in London, UK, believe that children born as a result of fertility treatments often get less and a little early, and may have some degree of late development that could explain shorter eye sight and less short-sightedness .

However this is an observation study, and as such can not determine the cause, says researchers, noting that future research will be able to analyze the interaction between genetic susceptibility and environmental impact.
