This is the temperature at which the molecules in the glass stop flowing and moving. Below this point if the bead has not been annealed correctly these stresses will remain in the glass. (unless the glass is then subsequently annealed).
The strain point varies for each glass depending on the manufacturer, elements contained within the glass and the coefficiency of the glass
Effetre glass
The annealing range is between 493C - 520C and the strain point is 448C
Bullseye
The annealing temp is 504C and strain point is 437C
