High-statistics data on the reactions $\gamma\gamma\to K^+K^-$ and$\gamma\gamma\to K^0\bar K^0$ are the last missing link in investigations ofthe light scalar mesons $f_0(980)$ and $a_0(980)$ in photon-photon collisions.It is believed that $f_0(980)$ and $a_0(980)$ resonances exhibit theirfour-quark structure in these reactions in a vary peculiar way. The workestimates the feasibility of measurements of scalar contributions near$\gamma\gamma\to K^+K^-$ and $\gamma\gamma\to K^0\bar K^0$ reaction thresholdsat modern colliders.
