我们可以根据光类型，波长，OD选择不同的。
选择需要注意以下几点
1. 需要进行防护的激光器波长范围，
2. OD值，光密度Optical Density：OD值越大，对相应波长范围防护能力越强，
3. VLT（可见光透过率）：VLT数值低于20%，需要在一定照明的环境中进行使用。
4. Frame（指的是镜框类型）：面部轮廓等信息。
根据类型区分：
UV
可见光
红外
UltraFast
X
根据波长和OD类型区分：

关于OD值的说明：
光密度（OD）[optical density]定义为材料遮光能力的表征。它用透光镜测量,表示被检测物吸收掉的光密度，是检测方法里出现的专有名词。
光密度没有量纲单位，是一个对数值，光密度是入射光与透射光比值的对数或者说是光线透过率倒数的对数。计算公式为OD=log10（入射光/透射光）或OD=log10（1/透光率）
| OD1 | 0.1 |
| OD2 | 0.01 |
| OD3 | 0.001 |
| OD4 | 0.0001 |
| OD5 | 0.00001 |
| OD6 | 0.00001 |
| OD7 | 0.000001 |
