Myopia (also known as nearsightedness) is a vision condition where one is able to see close objects clearly but far objects are blurry. It occurs when the shape of the eye is longer than usual, causing light rays to bend and focus images in front of the retina instead of on the retina.
AFFECTS YOUR CHILD
Myopia is a lifetime disease with no cure. The inability to see can be corrected through ways such as wearing glasses, contact lenses and lasik. However, these measures are only a form of vision correction and does not correct the elongation of the eye.
Myopia worsens with age. The earlier a child gets myopia, the higher the chances are of him or her getting high myopia at an older age. The age of myopia onset is the most important determining factor of high myopia later in life, beating other factors such as whether the parents have myopia or the number of books read.
NURTURE vs. NATURE
A person with high myopia has higher chances of losing their vision from a retinal detachment as compared to someone with perfect vision. On top of that, they are also prone to Myopic Macular Degeneration in their later years, which can lead
to vision loss.
When a young child becomes myopic, oftentimes they are unable to inform their parents as they are unaware that something is wrong with their eyes. Thus, myopia can be identified through the following symptoms:
Child holding things closer to his/her face
Child sitting close to the television
Child requesting to sit closer to the whiteboard at school
Child performing poorly in preschool
ABOUT THE HUMAN EYE
Our eyes are made out of several parts that work together to help use see. One key part of the eye is the retina. The retina is a thin layer of tissue that lines the inside of the back of our eye. It’s purpose is to receive the light that enters our eyes, converting the light into signals that are sent to our brain to help us see.
When we use our phones, we tend to hold these devices close to us, making it a near work activity. When we look at something that is too near, the images are actually blurred. This blur image is transmitted to our retina, causing the eye to elongate.
SCREEN TIME IN
RELATION TO MYOPIA
Screen time on handheld digital devices (such as smartphones or tablets) can lead to myopia because an image that is very close within arm's length, comes across as a blurry image. This visual blur is transmitted to the retina, causing it to protrude and remodel. As such, the eye becomes longer, resulting in myopia.
