A heat and steam generator 10 for eye application has a heat and steam generating member 11 making use of oxidative reaction of an oxidizable metal and is adapted to supply steam to eyes and surroundings. The heat and steam generator 10 is adapted to release steam from its side brought into contact with eyes and surroundings for a period of 1 to 30 minutes to maintain the skin surface temperature to which it is applied at 34°C to 43°C over a period of 1 to 120 minutes. The heat and steam generator 10 has a stiffness of 0.01 to 10 N/7 cm-width. The heat and steam generator is effective in improving near triad causing reduction in vision.
