all the pairs of glasses I have ever owned - I was feeling sentimental.
from left to right:
1st pair - ages 6-7
2nd pair - ages 8-9
3rd pair - ages 10-12
4th pair - ages 13-17
5th pair - ages 18-present (I'm 20)
(when I was 14 I started wearing contacts so my glasses' endurance increased due to lack of use)
p.s. the fact that my first three pairs of glasses were purple does not suggest I particularly like purple. It wasn't on purpose. It just kept happening.
