Brief Answer:
Reasons to suspect vision defects- given below
Detailed Answer:
Hi there,
Thanks for your query.
Firstly, there are two types of vision defects :-
(a) Myopia (short-sightedness) in which there is difficulty in seeing clearly the faraway objects; and,
(b)
Hypermetropia (Long sightedness) in which there is
blurred vision of the near objects.
There are certain patterns of child's behavior/complaints which should alert the parents to suspect that their child has vision problems :-
MYOPIA :-
* the child tends to be introvert, particularly in
severe myopia.
* The child may complain of
headaches,
eyestrain, and
fatigue when having to focus on something more than a meter or so away, as in the classroom where the child has difficulty in reading the blackboard.
* Most often, young children with myopia only complain of difficulties seeing things far away. The child may move closer to the TV to see clearly or, fails to catch the ball thrown at it.
HYPERMETROPIA
* The child had difficulty in reading books, or complain of eyestrain, headache and fatigue while studying. Hence, they tend to fare badly in school.
If your daughter has any of the above-mentioned problems, she should be taken to the optician at the earliest, for vision test. Both: the opticians and Eye doctors have vision charts, with the help of which the child is easily diagnosed as having either of the visual errors.
Nowadays, the computerized
optometry equipment can easily diagnose vision errors, even in small kids. The equipment also give instant and accurate power of glasses required to correct the vision error.
