What is the scientific opinion on plus lens therapy? **Plus lens therapy** is the theory that most myopia is environmentally triggered and that conventional corrective minus lenses increase nearsightedness over time. Thus the hypothesis that applying _plus_ lenses for nearsightedness will invert the environmental pressures and halt or reverse existing myopia. **_What is the scientific majority and minority opinion on plus lens therapy?_**

Plus lens therapy can indeed reverse myopia, but it does take time. Your eyes did not develop myopia in a few days.

The eye represents its environment. Fitting chicks, monkeys etc. with minus lenses always INCREASED the amount of myopia, while plus lenses always reduced myopia and resulted in hyperopia (lens compensation).

Putting monkeys in a confined environment showed a myopic shift. Monkeys in an open environment showed a refractive state about +1.00 diopters.

IMPORTANT: As I have said: Unfortunately, it does take time! Do not expect results after 1 week of plus lens therapy. That is why so many people give up and think that myopia is irreversible. You also do not build muscles after 1 week.

Kind regards.
