Hello,
(Forgive me for the phrasing of the title

). I'd thought it be interesting to ask, do you wear glasses?
Now if it isn't too intruding

, I'd like to know whether:
1. Do you wear prescription spectacles/glasses?
2. What type of vision defect do you have?
3. Do your parents also have this defect?
4. If you have any brothers/sisters, do they have the same defect?
4. When did you start wearing spectacles?
5. Roughly the age you began using computers.
I have recently been prescribed spectacles for I have myopic vision (can see short distances well, but not far distances clearly).
