Question

The eyr lens of an inverted image of the object on the retina.But we perceive objects as they are.How is it possible​

Answer 1

Answer:

The eyelens make an inverted image on the retina but we are able to see it how they are, this is because of the optical nerves and the brain which perceives the information and corrects it, and hence we are able to see the image correctly.

Working of eye:-

• Our eyeball is of about 2.3 or 2.5 cm diameter.

• The light enters through a thin membrane called cornea. It is bulged outwards.

• Some light rays may refract and some may enter the eyeball.

• The crystalline lens can adjust the focal length required to focus the objects which are either near to the eye or far away.

• There dark muscular structure called iris behind the cornea. It controls the size of the pupil.

• Pupil controls the entrance of amount of light in the eye.

• The image formed by the eyelens is inverted.

• The image is formed on the retina.

• Between the eyelens and the cornea we find a a liquid called Aqueous humour.

• And inside the eyeball we can find a liquid called vitreous humour. It help the eyeball to be in the shape correctly.

• The adjustment of the focal length of the lens is done by the help of ciliary muscles.

• The retina contains two types of cells namely cones and rods. The cones help to detect the colour of the image where as rods help in to detect the light.

• The information about the image is passed to the brain with the help of optic nerves.

• The information is perceived and processedin the brain and hence we are able to see the objects in the correct form.
