Assessment Room (part 1)
When I was observing what was going on I learnt that, some eye problems can trigger other problems such as cateracts. Cateracts cannot be removed util they have "matured" (reached a certain thickness), if they take them off too soon then the eyes will probably be damaged - let's use an orange as a sort-of-example:
If the skin on the orange isn't ripe and is too tight then you will probably damage the orange eg. the juice comes out, (please not the eye wouldn't do that, but it would be damaged). However if the cateracts are too thick, like the skin on an orange it will come off easily but lots of "pith" (you know that weird, tasteless white suff?) is left behind, it's like that...
