I was given the challenge of a new patient with a cylinder correction of -8.25.  They are in need of a bifocal prescription and want progressive or no-line bifocals.  In the past this patient would be unable to get a progressive bifocal with this type of prescription.  With new developments in lens technology this patient is now able to get progressive lenses.  Look into free form and digital surfacing for the latest in lens technology.

Today's illusion

optical illusion for the day. When you look at this image up close it looks like Albert Einstein, but from a distance of 10 to 15 feet you should see a image of Marilyn Monroe.

I'm an optician located in New Hampshire and this is my first blog.  I will be posting my insights into the eyecare profession and offer my advice on optical matters.
