The perfect vision
Your eyes are extremely precious and complex. They provide you with sight and are essential tools in our daily lives In order to preserve them, it is necessary to check periodically the optical and physiological part in order to avoid any problems and to keep an optimal visual comfort.
How to put a name on different
VISUAL DISORDERS
Normal vision is the result of precise focusing of light rays on the retina. Schematically, the light rays enter the eye through the cornea and then through the pupil in the center of the iris.
The light rays then reach the cristalline (lens of the eye), which changes shape depending on the distance to the object being viewed, to focus the rays onto the retina, where the light energy is converted into nerve impulses that are processed by the brain.
myopia
Myopia, also known as nearsightedness, is a vision disorder in which light does not focus on the retina but in front of it. It is estimated that one-third of the population is nearsighted today, but this eye condition is easily corrected with concave glasses.
Nearsightedness makes distant objects appear blurry while close objects appear normal. These symptoms may indicate that you have myopia: You have headaches; You feel tired, your eyes are tired; Your vision is blurred; You must move closer to distant objects, such as the TV. An increased risk of cataract, glaucoma or retinal detachment is often observed in cases of severe myopia.
hypermetropia
Hypermetropia, also known as hyperopia or far sightedness occurs when distance objects are seen clearly but near objects appear blurred. Hyperopia occurs when the incoming light is focused behind instead on the retina. It is due to an abnormally flat cornea or short eye. Hyperopia is often hereditary. Frequently present at birth, many children grow out of it. Young people with small hyperopia can compensate by accommodating without noticeable problems. They may feel uncomfortable when focusing on shorter distances. By making this effort for distance, some people cannot compensate when reading vision. Getting older some people remain able to see clearly at distance, but they face challenge at the time of prolonged reading due to insufficient accommodation.
Astigmatism
The result is blurred vision at all distances. Headaches, eye strain, and severely blurred vision are all symptoms of significant astigmatism. During normal eye examinations in schools, astigmatism is frequently missed. It may coexist with other refractive errors such as myopia and hyperopia. Astigmatism is corrected by using cylindrical lenses that bend light in one direction more than in the other. Using these lenses lengthens objects in one direction and shorten them in the other, like staring into a wavy mirror.
OVER 40 years
Presbyopia
Presbyopia is part of the natural. aging process of the eye, and can be easily corrected. Technically, presbyopia is the loss of the eye's ability to change its focus to see objects that are near. It is not a disease. It's as natural as wrinkles, and it affects everybody at some point in life. Presbyopia generally starts to appear around the age of 45. Presbyopia is often confused with hypermetropia, but the two are different. Presbyopia occurs when the eye's lens loses flexibility. Symptoms of presbyopia include: Blurred vision at a normal reading distance | The need to hold reading material at arm's length | Headaches from doing close work.
two ways of having your eyes checked
OPTOMETRIST OPHTALMOLOGIST
The Optometrist
is a health care professional with a Bachelor of science study. The main competences of an optometrist are the performance of refractive examinations, the eye functions, external and internal eye inspections. Follow-up, if necessary, with a referral to an ophthalmologist in case of suspected pathology.
The Ophthalmologist
has a practical and theoretical post-graduate university training in ophthalmology which is acquired after obtaining the federal diploma of doctor. They prevent, diagnose and treat vision disorders and eye diseases. They do also refractive examinations.
