Principles
- Do not provide glasses to kids aged 8 or younger (unless you are a vision care professional).
- Always try the customer with the zero lens.
- If in doubt, prescribe the weaker power.
- For reading glasses, prefer symmetric prescription.
- If glasses don’t help and a customer complains about poor vision, refer him/her to a vision care professional.
