Which formula is commonly used for selecting the best base curve in lenses?

  1. Snell's Law

  2. Gullstrand's equation

  3. Magnification formula

  4. Vogel's formula

The correct answer is: Vogel's formula

The other options, such as A Snell's Law and B: Gullstrand's equation, are used for determining the refractive power of lenses but not specifically for selecting the best base curve. C: Magnification formula is used for calculating the magnification of an object through a lens and is not applicable to determining the base curve. Therefore, D: Vogel's formula is the most commonly used formula for selecting the best base curve in lenses.
