1. Choose a comfortable frame: Selecting a frame in terms of its weight, shape, and size to meet individual needs is extremely important. We provide comfortable eyewear with a fashionable design that can be worn for long periods. Available in various frame styles including 33, 36, 52, 301, and 304.

2. VLT (Visible Light Transmittance): The attenuation of light by a filter. According to ANSI Z136.7, if VLT is less than 20%, users should ensure their working environment has extra illumination. Higher transmittance provides a better visual view.

3. Choose the relevant wavelength: Laser safety glasses must be used specifically for the wavelengths mentioned. Consult for the most suitable protection for your specific equipment.

4. High OD protection level: OD filters reduce specific wavelengths entering the eyes while allowing normal light to pass. Optical Density (OD) indicates the attenuation capability of the lens.
