Does the size of the eye increase as we develop from the stage the complete eye first forms to infancy and then to adulthood ?
First of all, I should quote the sentence from the MOST reliable ophthalmology sourcing in the world - American Academy of Ophthalmology:
Section 11 - "Lens and Cataract"
"The equatorial diameter of the unfixed human lens measures 2 mm at 12 weeks and 6 mm at 35 weeks. Both the growth and the maturation of lenticular fibers continue throughout life." The antero-posterior dimensions of the lens enlarge from 3 mm at infancy to 6 and even more in adult years.
"The lens continues to grow throughout life (page 7 the same source)
Secondly, the growth of the eye continues after birth - at the beginning the growth is fast and later the growth is much slower but still - there is GROWTH of the eye after the birth.
No. In fact the lens of the eye, which is nearly optically perfect in humans, does not change or grow after it is fully formed around week 26 of gestation. Interestingly this is why one of the cues for identifying young children is having small faces with large eyes. This also the case for puppies and cats and other animals, who are mostly cuter when they are small with large eyes.
This doesn't apply to compound eyes though.
