Abstract: The present invention provides a method for producing a composition capable of producing a composition having a small temporal change in viscosity and excellent in hardness (in particular, scratch hardness) of a cured film. The method for producing a composition of the present invention includes step 1 of heating a mixture containing a silsesquioxane having a cationically polymerizable group and metal oxide particles at a temperature higher than 60° C.; and step 2 of mixing the mixture obtained in the step 1 with a cationic polymerization initiator to produce the composition.

Abstract: One of both eyes (e.g., a right eye) is made to view a reference blurred image (Cp), the other of both eyes (e.g., a left eye) is made to view blurred images (Cp+1, Cp+2, . . . ), and information on sensitivity to a difference in blur amount between the blurred images (Cp+1, Cp+2, . . . ) that the other eye was made to view and the reference blurred image (Cp) that the one eye was made to view is acquired. Additionally, the other eye is made to view the reference blurred image (Cp), the one eye is made to view the blurred images (Cp+1, Cp+2, . . . ), and information on sensitivity to a difference in blur amount between the blurred images (Cp+1, Cp+2, . . . ) that the one eye was made to view and the reference blurred image (Cp) that the other eye was made to view is acquired.
