Myopia
Myopia is an anomaly of the vision described for the first time by Aristote (384-322 av. J.C.) A myope sees fuzzy by far, and beside the visual defect, somme myopias accompany of more or less serious anomalies of the retina.
Definition We speaks about myopia if image of the distant objects is formed in front of the retina. The importance of myopia is variable according to the eyes. In vision of near, there exists a distance to which a myope sees Net and without making effort. If myopia is important, this distance is reduced. This is why somme very short-sighted people read with a few centimetres of the text.
Various causes of myopia are known
- That is to say the eye is ” too much long” (an eye known as ” normal” a length of 23mm has). This is the case in the congenital glaucome. This rare disease can reach the children as of the birth. Because of increase in the ocular tension, the eye grows too quickly and weakens. Without treatment, evolution is done towards blindness. The diagnosis thus should be made as soon as possible. - That is to say the optical system of eye (formed by the cornea and the crystalline lens) is too powerful. - Lastly, certain cataracts make short-sighted.
Evolution Myopia often appears around the childhood and can increase until at approximately 20 years. We cannot predict at which rate/rhythm nor until with when it increases, because each eye is different. Myopias ” strong ” appear in theory earlier and can further increase well after 20 years age.
Ocular consequences Without glasses, a myope doesn’t have a good vision by far. We express in tenth. If the eye is in good state, the glasses enable him to see 10/10, or even more. The short-sighted ones have a risk more important to make a detachment of retina or a glaucome. To detect them, of the regular consultations at ophthalmologist are recommended. Some myopias known as ” strong ” are responsible of anomalies of the retina which worsen it during time and threaten the vision. The doctor can supervise their progression by examining the bottom of eye. Certain children make too visual efforts: they ” adapt ” too much. This can result in a ” distort myopie”. To recognize it and find the cause of it, we instills into the eyes an eye lotion which blocks temporarily; accommodation and we re-examines child.
Optical correction
Glasses of short-sighted were used as of the 15th century. Myopia is corrected by divergent glass. It replaces on the retina, image of the objects moved away, which are thus seen Nets. It is necessary to avoid correcting a myopia too much, which could involve eyestrain and headaches. Some under-are voluntarily corrected to improve comfort of the subject, even with depend of a moderate visual blur. Various types of corrective lenses and materials exist. The optician can guide the choice of them.
People who are nearsighted do have higher tension on their retinas due to the shape of the eye being more oval than round. The greater the myopia, the higher the risk. As we age, the vitreous gel also weakens adding more strain.
There are specific nutrients one can take that can strengthen the retina and related connective tissue such as lutein, zeaxanthin, omega-3 fatty acids, bilberry, gingko biloba, vitamin C and glucosamine sulfate for example.
Also a diet high in vegetables (particularly the green, leafy type), low in refined carbohydrates, and void in unhealthy oils such as vegetable oils and food fried in oils helps maintain healthy vision as well.
Doing daily eye exercises can also help maintain and even improve vision. Dr. Grossman is one of the leading vision therapists in the Country. He is the author of 6 books on natural eye care.
Daily eye exercises also help maintain healthy vision. For a demo of 3 great eye exercises by Dr. Grossman, one of the Country’s leading behavioral optometrists, go to http://www.youtube.com/watch?v=W10j2fL0hy0
