Something i think should be added in B42.20

recently came back to the game for B42 and i noticed many things, 2 of them though made me think about something, 1 is that short sighted is an actual downside now and does affect you, 2 glassmaking seems kinda useless other than fixing the windows in your base that zombies broke. what if they allow, at high levels like 8-10, the making of "short sighted" items, like a "prescription" welding or gas mask, wouldnt make short sighted downsideless since youd need high level in the skill but it would make the skill more worth. wdyt?
