Far Point of Clear Vision Formula Calculator Usage Guide

Learn how to use the Far Point of Clear Vision Formula calculator and its working principles

How to Use This Calculator

  1. Enter the corneal power in diopters (D). This is typically between 40.00 and 48.00 D.
  2. Enter the aqueous humor depth in millimeters (mm). This is typically between 2.00 and 3.00 mm.
  3. Click the "Calculate" button to compute the far point of clear vision.
  4. The result will be displayed in diopters (D).

Working Principle

The far point of clear vision is calculated using the formula:

Far Point (D) = Corneal Power (C) + Aqueous Humor Depth (d)

This formula is based on the principle that the far point of clear vision is determined by the total refractive power of the eye, which includes the cornea and the aqueous humor.

When to Use This Calculator

This calculator is particularly useful for:

  • Optometrists and ophthalmologists during eye examinations
  • When determining refractive errors
  • When planning corrective lens prescriptions
  • For educational purposes in ophthalmic and optometric training
