Buying glasses
Where should I buy glasses online?
See buying glasses and lenses.
How do I measure pupillary distance?
Zenni Optical has a great article on this. [Find that here
Are polycarbonate lenses bad for your eyes?
The fact that they are polycarbonate makes no difference to your eyes.
Why are my glasses giving me a headache?
When myopia increases, people's headaches tend to get worse. This is largely due to the shrinking field of view higher diopter correction gives. There's a huge amount of variation in general in this area. It's safe to say though, the higher your diopters, the worse the headaches.
Test lens kits
Do I need a test lens kit?
No, generally you don't need a test lens kit. It may be helpful if your myopia is particularly complicated. Most people don't buy a test lens kit and do fine.
How do you use a test lens kit?
You insert the lenses from the kit into the really dorky-looking glasses. This way you can test different lenses and how they work.
Where can I buy an optometrist test lens kit?
Plus lenses
How do plus lenses work?
Plus lenses make you more short-sighted, not less. They are for the most part useless when it comes to improving myopia.
Diopters
What should I reduce to?
See Guide:Reducing your correction.
Is it ok to use several different diopter glasses?
Generally, you want one pair of normalized, and one pair of differentials. You can wear more correction when doing important things such as driving at night - very important to do this safely.
Should I stop wearing glasses?
No, unless you have low myopia. See Explainer:Should I stop wearing glasses?
I have low myopia. Can I stop wearing my glasses?
If you have below 2 diopters of myopia, you can definitely look at not wearing glasses any more.

Contact lenses
Should I use glasses or contact lenses for close-up?
You can wear contact lenses with plus lenses to achieve the same effect as a pair of differentials. It's generally preferable to wear glasses in general, but people have managed to improve their eyesight with contact lenses.
