Special eye glasses

This is a special type of googles for people in the camps settling after natural disasters. All glasses can be adjusted to the right degree so people can still see clearly even though their eye glasses may had been broken in the earthquake, etc.
What a smart idea! Salute to the kind hearted enterprise to design these.
This is a left over from an event.

Ah Lun proved that it works! While I felt dizzy after trying.
