What is binocular vision?
Each of our two eyes sees a slightly different picture of the world. If you have binocular vision, it means your brain can take the two pictures from the two eyes and put them together into a single three-dimensional perception of the world around you. This is a complex skill that is quickly lost when the eyes don’t line up. Without binocular vision, your depth perception may be limited.
One of the main benefits of binocular vision is to be able to judge depth and speed of objects well. Children with poor or no binocular vision can have difficulty with these tasks. This may lead to problems with:
- Pouring juice into a cup
- Catching or hitting fast moving balls
- Walking up or down stairs
- Judging how quickly a car is approaching while crossing roads
Also, there are certain jobs where good binocular vision is important and necessary. These include flying planes and performing surgical operations.
If you close one eye you can see what loss of binocular vision is like. At arms length try pouring water into a glass or bringing two pencil ends on top of each. It is more difficult than when both eyes are open. This is because your skill in judging depth is poorer.

How can my stubborn child be tested for glasses in early childhood even though he does not read?
- A Paediatric ophthalmologist can detect the need for glasses through a complete eye exam.
- Typically, the pupils are dilated in order to relax the focusing muscles, so that an accurate measurement can be obtained. By using a special instrument, called a retinoscope, your eye doctor can arrive at an accurate glass prescription.
- The eye doctor will then advise parents whether there is a need for glasses, or whether the condition can be monitored.
- At Utsav Eye Clinic, Kharghar we are equipped with special vision charts for Kids that can be used to assess vision in very young children as well.
