When a visit to the ophthalmologist is made, he/she conducts a thorough eye exam to understand whether or not the patient is able to see clearly without any blurs. These examinations are useful in finding out the extent of any damage or if there is a possibility that the patient may lose vision in future.
These examinations are done to assess various factors like whether or not the eye is able to see far off objects. It is also used to check if the pupil has changed it s size because that also indicates problems with the eye sight. Also, peripheral vision is tested with the help of these examinations.
Also, this eye exam should be done regularly right from the childhood so that any defect in the vision can be detected early and corrected immediately. It is very important that children are for these exams because if there is any problem, then it can be rectified early and so there will not be any problem in future. If the problem is detected early, then it can be cured easier than if the problem goes into an advanced stage where it will be much more difficult to cure.
