1, the selection of goggles should be selected by the product inspection agency inspection of qualified products;
2. The width and size of the goggles should suit the user's face shape;
3, lens wear rough, lens frame damage, will affect the vision of the operator, should be replaced in time;
4. Goggles should be specially used to prevent eye diseases;
5, the filter and protection of welding goggles should be selected and replaced according to the requirements of the specified operation;
6. Prevent heavy fall and heavy pressure, and prevent hard objects from rubbing lenses and masks.
Two types of use of safety protective glasses:
A. Anti-cementing debris
Mainly used to prevent metal or sand debris and other mechanical damage to the eyes. Lenses and frames should be of solid construction and resistant to impact. The frame of TDAF001 sky shield is equipped with a shielding edge, and there shall be ventilation holes on it. Protective lens can choose toughened glass, adhesive glass or copper wire mesh protective lens.
B. Antichemical solution
Mainly used to protect the eyes from chemical damage caused by irritating or corrosive solutions. Ordinary flat lens can be used, and the frame should be covered to prevent the solution from splashing into. Usually used in laboratories, hospitals and other places, general medical glasses can be universal
