The maximum negative eye power, referring to the highest degree of myopia (nearsightedness), is subjective, but can reach significant levels.
According to the provided reference, there isn't a defined limit, but generally:
- High myopia: Considered to be -6.00 D or greater.
- Extreme cases: Can reach -20.00 D or more.
This means that while -6.00 D is generally considered high myopia, some individuals can have significantly stronger prescriptions, even exceeding -20.00 D. The severity varies from person to person.
