==Why ~~Are My Glasses Giving Me A Headache~~?==

====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?===

[[File:Trial test lens kit.jpg|right]]

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.

==Should I use glasses or contact lenses for close-up?==

==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.
