Dyskinesias are uncontrollable involuntary movements particularly affecting some people with Parkinson's Disease (PD).

This video has been made available in order to widen the awareness of PD sufferers experiencing dyskinesia that blue lens glasses may provide a certain degree of relief for some sufferers.

This video was recorded under medical supervision whilst the person was having a UPDRS assessment in 2003.

Blue glasses do not work effectively for everyone however may be worth trying by anyone suffering with l-dopa induced dyskinesias.

The exact specification for the blue lenses follows. Any optician should be able to make the lenses for you.

TINT -- BPI BLUE (2 bottles to 1 quart of water. Must be freshly mixed!!! Tint even
2 days old will not give the appropriate results!!)

LENSES-- CR39 PLASTIC (These are standard plastic lenses. You cannot use those light weight lenses -Hi Index or Polycarbonate for this tint! They will not tint properly.)

TIMING--2 HOURS (It will take right at 2 hours in the tint solution for these to be dark enough to be effective.) ***They will be DARK***

INTENSITY--50 % LIGHT TRANSMISSION (These would be classified as sunglasses in the optical industry. This degree of tint **#3 Blue** is dark and may be too dark for individuals with cataracts. Hopefully your optician will be willing to work with you in achieving the intensity you need.)

This specification was extracted from the following website (it is recommended that you visit this website to get some differing experiences/views of blue glasses):

As can be seen in the video, staring hard at bright blue paper also helped control dyskinesia for this person.

These are not sun glasses and offer no protection against ultra violet rays. Great care must be taken whist wearing them when moving around as they cut out a substantial proportion of available light. Depth perception may be affected and they should not be used when driving.
