This course opens up the issues that optical professionals should consider when prescribing a tint or filter. It's not just for professionals though, if your child has special needs, is underachieving at school, you should watch this. And if you are a teacher, this short course is invaluable. We address various types of assessment, how gamuts can be critical in tint or lighting, when two wrongs may make a right, and where a right can sometimes translate into a wrong. If your child is using overlays, are they really acceptable? Are assessment techniques used by optical professionals at an adequate standard? Have the regulation and standards been poorly made. Is univariance the only acceptable method for tint determination?

If you have a child with problems that require a tint or filter, do you know the options in determining the optimum one?

Should you insist the optical professional gives you a prescription with all the information necessary for another professional to dispense the filter, and where necessary, modify it?

How do you assess claims made by commercial companies as to the primacy of their methods?

Some claims do not bear scrutiny and you may pay a lot of money for a basic service.

And if you are a professional- do you prescribe the optimum filter for your patient. The issues are addressed in this course.
