   4 days ago · A polarizing filter, or polarizer, is used to intensify blue skies, brighten or saturate colors, and reduce reflections, glare and haze in images. The same as other types of lens filters, polarizers sit over your lens and can either screw into your lens’ filter thread or be used with filter holders.

   3 days ago · There are a lot of third-party and manufacturer toric IOL calculators online. With very basic maths, anyone can calculate what spherical power an eye needs by simply knowing the shape of the front and the length of the eye. Calculating a toric lens means calculating two lenses – one for each axis.

   How do you calculate a toric lens?

   • Calculating a toric lens means calculating two lenses – one for each axis. This is still rather simple but people have put a lot of time and effort into refining the process by taking into account the expected lens position, anticipated tilt, posterior corneal astigmatism, etc., so it makes sense to rely on robust, tested calculators.

   How do you calculate contact lens vertex correction?

   • This consideration is paramount for high-power lenses, where even slight changes in distance can significantly affect the perceived power of the lens. The formula for calculating contact lens vertex correction is as follows: \ [ Fc = \frac {F} {1 - xF} \] where: \ (x\) is the change in vertex distance in meters.
