Human Eye and Vision starts at 8 and continues till grade 12.
QuestionsToday has an evolving set of questions to continuously challenge students so that their knowledge grows in Human Eye and Vision.
How you perform is determined by your score and the time you take.
When you play a quiz, your answers are evaluated in concept instead of actual words and definitions used.
See sample questions for grade 11
A person can see objects clearly only when they are between 50 cm and 200 cm from his eye. What defect of vision does he have?
A person with hypermetropia has a near point at 75 cm. What is the power of the lens required to correct this defect so that the near point is at 25 cm?
Describe the process of image formation in the human eye.
Explain why a person with astigmatism cannot see both horizontal and vertical lines clearly at the same time.
Explain why a person with myopia cannot see distant objects clearly.
If the power of a lens required to correct a myopic eye is -2.0 D, what is the focal length of the lens?
Name the defect of vision in which a person cannot distinguish between certain colors.
Name the transparent front part of the eye that covers the iris, pupil, and anterior chamber.
The eye lens forms a sharp image on the retina when the object is at a distance of 1 m. If the focal length of the lens is 0.9 m, is the image formed in front of, on, or behind the retina?
What is presbyopia and how is it corrected?
What is the function of the aqueous humor in the eye?
