If you are looking to develop optical instruments for use in a Low Earth Orbit satellite deployment lasting a year or more, then use radiation resistant optics to guarantee good transmission for the entire length of the mission. However, sometimes there may be a performance criterion (wide operational bandwidth, high resolution, athermal performance) that is considered more important than longevity.
