Can I lower my prescription slightly for distance glasses meant for moderate distances?

Hi,

I'm buying distance glasses for the first time and I'm wondering if there is any reason to lower my mild prescription of -0.5/-0.75 to -0.25/-0.5. These glasses would be used more or less only for TV viewing at an 8 foot distance. Because this is not a particularly long distance, could I get away with a slightly weaker prescription? Would this be of any benefit to my eyes?
