Long Sightedness or Hyperopia is an eye condition where distant objects are clear and most often near objects are clear as well, but it requires an excessive amount of eyestrain to make the near objects clear. In a relaxed long sighted eye, the image is focused behind the retina, the back of the eye. To focus the image on the retina, either excessive amounts of focus must be exerted by the individual, or a plus spectacle lens is required to be placed in front of the eye (to reduce this strain). These glasses will allow the spectacle wearer to see all distances clearly.
Long sightedness is a common contributor to behaviour and learning difficulties in children, especially poor concentration. This is because so much effort is required to look at and hold things clear on a page, that they either get sore eyes or lose concentration and get very frustrated with their school work. It is easily treated with simple reading glasses, and dealing with this problem can result in a massive improvement at school.
So if your child struggles at school, it could be long sightedness, so definitely check this out at Eye CU Optometrist.
