Purpose
To compare the progression of myopia and axial length using progressive addition lenses (PAL) and single-vision lenses (SVL).

Methods
A literature review of studies with reports on PAL in slowing myopia progression which were published in English. The included studies provided results of progression of myopia and axial length. Journal articles that met the inclusion criteria were rated according to the level of evidence. Level of evidence was assigned based on the study design and methodological quality. The articles were grouped according to the power of addition lens +1.50 D and +2.00 D The primary outcomes were the end spherical equivalent refractive error. Secondary outcome is changes of axial length.

Results
Five articles were reviewed. Four articles were assigned to level I, one article were assigned to level II. The changes in refractive error from baseline to final follow up in PAL group compared to SVL group were appeared to clinically significant in most studies (p< 0.05). Most journals that reviewed report that the use of PALs slowed myopia progression and elongation of axial length when compared to the SVLs. These results were statistically significant.

Conclusions
Progressive addition lenses seems to be more effective in slowing progression of myopia in children than single vision lenses. The elongation of axial length seems to be retarded by the use of progressive addition lenses. This literature review suggested that progressive addition lenses seemed to be the treatment of choice in slowing progression of myopia in children
