solution is very much depends on wat type of lens u r using. silicone hydrogel lens best wash and soak with optifree or solocare aqua.

normal lens then just use back the same company solution, ie B&L softlens 38 then use B&L renu becoz the lens in the plastic container is soaked with respective company solution.

thanks
depends on brand and type, for example, freshkon 38 highest is till -8.00, while freshkon 58UV reaches -10.00

some reach -12.00. how much power of lens u need?

thanks
