They, most likely would need to wear a welders mask, which is auto darkening. Along with other PPE. I suggest, perhaps also looking here for any other issues: http://www.hse.gov.uk/welding/

Safety glasses under the mask. They will complain the glasses steam up but it only means that their RPE does not fit correctly. Sometimes it's really hot and the glasses do steam up. You can think of providing anti-fog spray or something similar.

You have not given us enough information.
You need to specify the welding process
Most arc welding processes produce UV radiation and this causes arc eye. You need to choose a filter that removes this and the shade you need will depend on the welding conditions (current) and the material that is being welded.
Gas welding produces a lot of infrared radiation, so the choice of filter will be different.
The standard that specifies what choices you need according to process, conditions and materials is BS EN 169. Surprisingly I cannot see anything on the HSE site about the choice of filter. A reputable supplier will help you choose the correct shades.
Don't forget that welders also tend to do things like grinding, slag removal, and for these they need eye protection that is clear, but resistant to impact.

With electric arc welding you need to consider more than just eye protection. As has been stated, this process creates high levels of UV. This is the wavelength UV-C which is particularly damaging to the skin. So for electric arc welding you need to protect the whole skin, i.e. a full face shield, but also appropriate clothing, i.e. no short sleeves and clothing that can protect against UV. No unbuttoning of coveralls in hot weather, etc. - yes I have seen severe 'sunburn' from this!
Your risk assessment should also take account of others in the immediate vicinity who might have exposed skin.

Some very good advice for you above. As Jane says you may find them doing other things like grinding, ours do so we have suitable welding masks that also include a clear part to the suitable grade for this.
Also, consider what RPE you many need to provide, with the fumes caused you may need to consider air-fed packs, torch extraction and local exhaust ventilation.
We use a mixture of these dependent on the welding area.

On the other hand, with a decent facemask with inbuilt powered rpe and a flip-top with the filter glass in, the fixed rpe mask also has a protective lens...usually polycarbonate. Why would anyone have someone work with passive RPE, eye protection and face/eye protection, and be so hot their perspiration fogs the glasses....then give them a spray to coat the glasses in? Weird. This is the 21st isn't it?
