Side effects - Ivory wave and eye focusing

[Tamis]

Swim experienced on two seperate time vision problems in the morning following ivory wave usage (300+ mg).

swim could not focus his vision correctly making it impossible to read the time on his computer for example. Large caracters could still be read and driving etc was not impaired.

Those side effects did not last more than 24h.

Did any swiy experience this ?
Could it be the mixing of alcool, benzo and cannabinoid ? May be the lack of sleep though this has never happened to swim with other products while seriously lacking sleep ?
And lastely how would this be explainable on the medical aspect ??
