Optics question with radius of curvature

Click For Summary
SUMMARY

The discussion focuses on calculating the effect of changing the radius of curvature of a contact lens on its optical power. The refractive index of the liquid between the lens and the cornea is 1.336, while the lens material has a refractive index of 1.490. Using the lens maker's formula, the impact of altering the posterior surface radius from 8 mm to 7 mm is analyzed. This change will increase the optical power of the lens system, enhancing its corrective capabilities.

PREREQUISITES
  • Understanding of the lens maker's formula
  • Knowledge of refractive indices
  • Familiarity with optical power calculations
  • Basic principles of geometrical optics
NEXT STEPS

Hi, I am a first time poster and I am completely lost with this question. Any help would be greatly appreciated

Filling the space between a contact lens and the cornea is a small quantity of liquid of refractive index of 1.336. Assuming the refractive index of the lens material is 1.490 find the effect on the power of the system of changing the radius of curvature of the posterior surface of the contact lens from 8 mm to 7 mm.
