    摘要: A method of manufacturing methallyl sulfonate, which comprises: forming a sulfur trioxide-dialkyl sulfoxide complex by effecting reaction between sulfur trioxide and dialkyl sulfoxide as mixed at the ratio of more than 0.8 mol of the latter to 1 mol of the former in the presence of an inert solvent; effecting reaction between said complex and isobutylene, in an amount of 0.9-1.2 mols of isobutylene per 1 mol of sulfur trioxide, by applying a temperature in the range of 10.degree.-80.degree.C; and neutralizing the reaction product with a base.

    摘要: To let one confirm the location of a contact lens which has been lost when one has intended to apply it to or remove it from the eyeball, a polarizing filter is used. The surface or side surface of a contact lens is coated with a polarizing filter so that when the contact lens has been lost, the location of the polarizing filter that is coated on the contact lens is allowed to be confirmed easily through a polarizing plate.
