Do you not see any contradiction between "they are of no significance" and "my FO was apparently dazzled for a short while"? And if they are of no significance, why is it an offence under the ANO and why have there been prosecutions for endangerment (article 137) as well as the summary offence (article 222) of directing or shining a light at any aircraft in flight so as to dazzle or distract the pilot? Why is it OK to limit someone's vision for any period of time at all, especially when flying?
Dazzle can be classed as a temporary injury (= ABH); some people who have been struck by lasers have had dazzle effects which have lasted for several hours. Some are more susceptible to this than others, and it will also depend on laser power and proximity. Injury symptoms beyond the initial dazzle can also develop with time - this is the same effect as with sunburn, where exposure to the sun and finding out how badly you have burnt yourself can be hours apart.
I am pleased to know you suffered no ill effects from your laser strikes (others have not been lucky) and hope you reported them as required by the MOR scheme and now by EC 376/2014.
