Myopia – What it Is and What You Can Do about it
One of the most popular reasons for needing specs is myopia
shortsightedness, or myopia, is a situation in which objects a way away are obscured either because the eye is overly long or overly strong. It is the effect of both environmental and familial factors.
How shortsighted you are is determined by how badly working the cornea and lens of the eye are – as well as how long your eye balls are! Normally, the eye processes a visual light image by interpreting the light signals and transmitting them into electrical signals in the retina. If the eyes focus the light ahead of time, you are myopic.
Unlike many other aspects in life, myopia tends to improve with time. Nobody is definitely sure as to why this is, on the other hand it may be the lens becomes stiffer with age and so can’t focus the rays of light so acutely. What then follows is the focal point of the light, becomes closer and closer to the retina.
Overall, 25 percent of those living in the United States are myopic.
An eye care practitionerwill examine a child’s eye and vision very carefully and work out if there is a problem with how they focus images.
The type and extent of myopia is determined by additional testing. These tests include an evaluation of the child’s binocular vision, his eye movements, his ability to converge and focus on targets close-up, and his ocular health. Dilation of the eye allows the doctor to check for complications of ROP, diabetes, or degenerative myopia.
The optician may deliberately choose to dilate a child’s pupils to prevent their natural tendency to over focus confuse the prescription generation process. .
If you have shortsightedness, you will need to have spectacles prescribed. If your child has been diagnosed with shortsightedness and are under 4, then they may get away with not wearing spectacles unless their vision is particularly bad.
Once a child starts school, then being able to focus on the board becomes important for learning, etc. So they should be regularly assessed for the need to wear spectacles or the need to change their prescription.
The specs are then usually worn full time, except for children with difficulty with convergence (esophoria), who may remove their eyeglasses for close work.
