(1) Background: According to the World Report on Vision published by WHO, 123.7 million people around the world have vision impairment due to uncorrected refractive errors. Vision impairment affects many aspects of our lives, and it is related to low academic performance; (2) Methods: A prospective and multicenter study has been carried out in 1400 optical centers in Spain. A visual screening was carried out by optometrists on children aged between 6 and 12; (3) Results: 6673 children of primary school have been checked. The multivariate analysis reveals that 5.2% of the poor academic performance is related to vision. Poor academic performance was independent and significantly affected by sex, age, near vision, hyperopia, binocular dysfunctions, and bad ocular motility; (4) Conclusions: Vision plays a key role in optimum academic performance; consequently, the early detection of refractive errors and other visual problems is essential to improve the academic performance of schoolchildren.

Currently, a large part of the world population does not have access to quality visual health services. Most of this population lives in developing countries, thus it is necessary to screen the general population to identify ocular abnormalities such as refractive errors and amblyopia in schoolchildren. The protocols for complete visual screening or examination vary widely regarding the type of tests and procedures, although most of them use visual acuity (VA) and refraction as the main diagnostic criteria. These clinical tests should have good quality and precision, that is, a high sensitivity and specificity. Unfortunately, in most clinical and epidemiological studies, the quality and accuracy of the tests used are unknown, which makes it difficult to compare results and to estimate the real conditions of visual problems in the population. Therefore, the objective of this literature review was to describe the main tests and protocols used in epidemiological and clinical studies for the detection of refractive errors in children.

Background: Academic performance at different educational levels has become a very important subject of study in local, national and international institutions. A visual system working properly is critical to improving academic performance. It is important to check children’s vision during the different stages of elementary school. Methods: A visual screening was carried out in elementary school children, aged between 6 and 12, across Spain. The screening included: the collection of demographic data, surveys of children and families about their vision habits and a basic optometric screening to detect visual problems. Results: Children with bad academic performance had worse visual health than those with good academic performance. Conclusions: It would be highly recommendable to introduce policies that ensure the early detection of visual disorders in schools and primary care in order to improve the academic performance of elementary students.

The poor academic performance of students could be as a result of irregular supervision of teachers. The study investigated the relationship between teachers’ regular supervision and student academic performance in public secondary schools in Ekiti State, Nigeria. Descriptive survey and correlational research were used for the study. The population for this study was 203 schools and 7,538 teachers in public secondary schools in Ekiti State, Nigeria. Validated instrument titled “Teachers’ Regular Supervision Questionnaire (TRSQ) was employed to collect data from the sample while a profoma was used to obtained data for academic performance of students. The study revealed that there was a positive significant relationship between regular supervision of teachers and student academic performance in public secondary schools in Ekiti State, Nigeria. The study recommended that principals and other internal supervisors should ensure regular supervision of teachers.

Vision impairment is estimated to affect 285 million people in the world, where 16-20% experience blindness, from the number of blindness suffered at the age of 40-50 years. Cataract seninis is all lens opacities that are found in old age that is above 40 years. The purpose of identifying and collecting frequency data Profile of Senilis cataract patients at the age of 40 years and above at RSI Siti Rahmah Padang in 2017. The research method is descriptive type of research, this study data taken is secondary data, In this study data was taken from the Medical Record at RSI Siti Rahmah Padang. When the study was conducted in February-August 2018, the population of this study were all cataract patients at the age of 40 years and above at RSI Siti Rahmah Padang in 2017 with 80 samples. Data analysis is univariate presented in the form of a frequency distribution table. Results From 80 respondents as many as 40 people (50%) were in the age range of 60-69 years, as many as 42 people (52.5%) patients were male, as many as 31 people (38.8%) patients with high school education and 35 people (43.8%) patients work as private companies. Conclusion In general, most patients are at the age of 60-69 years, the most sex is men, the highest education is high school and most patients are private.

The implementation ofthe capitalist system has eliminated the Islamic values in economic practice. After the financial crisis hit the world, the capitalist system reaped many questions and its greatnessbegins to be doubted. The capitalist system implementationprecisely creates new problems in the economy. The concept of individualism which is the main key in capitalist practice only creates economic injustice and misery of the poor. The only economic theory that is expected as a light in dealing with economic problems is an economic system that is able to create justice,the welfare of all parties and blessings both the world and the hereafter. The theory is the Islamic economics which in practice is inseparable from Islamiceconomic law. Islamic economic law that underlies the Islamic economic system is totally different from the capitalist economic system.Keywords: Islamic Economic Law; Islamic economics; Capitalist Economy

The Brain

Refraction of the eye means its ability to bend (refract) light in its own optical system. In a normal state, which is called emmetropia, light rays passing through the optical system of the eye focus on the retina, from where the impulse is transmitted to the visual cortex of the brain and is analyzed there. A person sees equally well both in the distance and near in this situation. However, very often, refractive errors develop as a result of various types of influences. Myopia, or short-sightedness, occurs when the light rays are focused in front of the retina as a result of passing through the optical system of the eye. In this case, a person will clearly distinguish close objects and have difficulties in seeing distant objects. On the opposite side is development of farsightedness (hypermetropia), in which the focusing of light rays occurs behind the retina — such a person sees distant objects clearly, but outlines of closer objects are out of focus. Near vision impairment in old age is a natural process called presbyopia, it develops due to the lens thickening. Both myopia and hypermetropia can have different degrees of severity. The variant, when different refractive errors are observed in different eyes, is called anisometropia. In the same case, if different types of refraction are observed in the same eye, it is astigmatism, and most often it is a congenital pathology. Almost all of the above mentioned refractive errors require correction with spectacles or use of contact lenses. Recently, people are increasingly resorting to the methods of surgical vision correction.
