The size of a growing child’s eye quickly adjusts to focusing in the dominant spectral band of illumination. The predominant type of lighting plays an important role in the formation of the eyeball in childhood. Everyday use of lamps with whose spectral composition is dominated by the red component can lead to lengthening of the eye (myopia or near-sightedness) during the most critical period of development. These changes may be irreversible. We report measurements of various parameters of the eyes of quail chicks at different ages during the maturation period. Acoustic microscopy was used for measurements. The measurements were made in two groups of birds. Everyday lighting in the first case was with an incandescent lamp and in the second case with an LED lamp with a dominant spectral band of 525–700 nm. The results demonstrate the drawbacks of using incandescent lamps as everyday lighting for children during the formation of the eyeball.
