A process for preventing or treating myopia includes applying a pulsed energy, such as a pulsed laser beam, to tissue of an eye having myopia or a risk of having myopia. The source of pulsed energy has energy parameters including wavelength or frequency, duty cycle and pulse train duration, which are selected so as to raise an eye tissue temperature up to eleven degrees Celsius to achieve therapeutic or prophylactic effect, such as stimulating heat shock protein activation in the eye tissue. The average temperature rise of the eye tissue over several minutes is maintained at or below a predetermined level so as not to permanently damage the eye tissue.
