Daily use of diversified segmental defocus optimization (DSDO) spectacle lenses delays the onset of myopia among children, according to a study.

Yuchang Lu, M.D. and colleagues evaluated the efficacy of DSDO spectacle lenses with or without 0.01% atropine for myopia prevention. The analysis included children (aged 5 to 12 years) who were randomly assigned (1:1:1) to receive DSDO spectacles with placebo eye drops (DSDO group; 121 individuals), DSDO spectacles with 0.01% atropine eye drops (DSDOA group; 125 individuals), or single-vision spectacles with placebo eye drops (control group; 124 individuals).

The researchers found that the one-year cumulative incidence rates of myopia in the DSDO, DSDOA, and control groups were 5.8%, 4.8%, and 15.3%, respectively. The percentages of participants with fast myopic shift after one year were 15.7%, 9.6%, and 42.7%, respectively. There was significantly lower one-year cumulative myopia incidence in both the DSDO and DSDOA groups (DSDO: difference, 9.5%; DSDOA: difference, 10.5%).

Results were similar for the percentage of patients with fast myopic shift (DSDO: difference, 27.0%; DSDOA: difference, 33.1%) compared with the control group. There were no significant differences between the DSDO and DSDOA groups.

"The daily use of DSDO spectacle lenses delayed the onset of myopia and slowed its progression among children without myopia; thus, the use of these lenses might be an effective alternative preventive method for myopia in children without myopia," the authors write.

These should be available today and they seem to help kids delay nearsightedness.

Myopia is primarily caused by lack of exposure to sunlight and thus attenuated dopamine production from the retina which stops axial elongation of the eye due to extended near work.

DSDO and 0.01% atropine appears to be effective, but the behavior modification as outlined above is the primary defense.

Generations of people were told that myopia was genetic which is almost entirely untrue.

Wouldn’t have helped with me, as I was born very nearsighted. My first visual memory is of being 4 years old and getting my first glasses. 66 years later, I still remember looking across the street from the optometrist’s office and seeing leaves on a tree and bricks in the wall of a building. A whole new world, just like that.
