Normalized reduce the [[blur horizon]] by just enough to give good stimulus, but definitely not enough to make the world significantly | Normalized lenses reduce the [[blur horizon]] by just enough to give good stimulus from [[blur]] and [[double vision]] challenge, but definitely not enough to make the world significantly [[blur]]ry. Good normalized lenses allow the user to continue daily activities without impairment, except night time driving, for which [[20/20 correction|a higher correction]] is a very good choice. (Always ensure your eyesight meets the minimum legal requirement while driving.) Normalized lenses induce a small amount of [[myopic defocus]], which has been shown to reduce axial length in a clinical study.<ref>{{Cite journal |last=Read |first=Scott A. |last2=Collins |first2=Michael J. |last3=Sander |first3=Beata P. |date=December 2010 |title=Human Optical Axial Length and Defocus |url=https://iovs.arvojournals.org/article.aspx?articleid=2126435 |journal=Investigative Ophthalmology & Visual Science}}</ref> | ||

When you're starting out with EndMyopia, '''you will likely have a lot of [[ciliary spasm]] and eye strain'''. Lucky you! This means [[Explainer:Why early gains are so fast|your early rate of improvement will be staggeringly high]], before it slows and you enter the long game of much slower improvements. | When you're starting out with EndMyopia, '''you will likely have a lot of [[ciliary spasm]] and eye strain'''.

The golden rule with all of EndMyopia: [[Guide:Not reducing too quickly|don't reduce too quickly]]. It is recommended that you reduce no more than 0.25 diopters from [[20/20 correction]]. This gives plenty of good stimulus and blur challenge for the majority of moderate myopes. If your myopia is higher (7 diopter+) or you need more challenge for stimulus, you may consider doing a 0.5 reduction. But in general '''there are no benefits to reducing more quickly''', and most of the time reducing too quickly will lead to problems than faster progress. Take your time! | The golden rule with all of EndMyopia: [[Guide:Not reducing too quickly|don't reduce too quickly]]. It is recommended that you reduce no more than 0.25 diopters from [[20/20 correction]], or 0.5 D from full correction. This gives plenty of good stimulus and blur challenge for the majority of moderate myopes. If your myopia is higher (7 diopter+) or you need more challenge for stimulus, you may consider doing a 0.5 D reduction (0.75 D from full correction). But in general '''there are no benefits to reducing more quickly''', and most of the time reducing too quickly will lead to problems than faster progress. Take your time! | ||

"What if I just need to use my phone for like a minute?" CHANGE YOUR GLASSES. If you are asking yourself "should I switch to differential glasses for closeup?" the answer is always YES. | "What if I just need to use my phone for like a minute?" CHANGE YOUR GLASSES.

'''A:''' It's just a new pair of glasses, they probably don't care. (How much do ''you'' care when you see someone else wearing a new pair of glasses?) | |||
'''Q:''' ... but high schoolers care about everything, they will notice!!! | |||
'''A:''' Sure, that's fine! Just tell them something short and truthful, and don't make it a big deal (unless you want to). If it's not a big deal to you, it won't be a big deal for them, either. | |||
=== [[Pseudomyopia]] === | |||
If you have [[pseudomyopia]], do you need to wear normalized glasses? Probably not! Only wear normalized glasses when you need them to be able to see things. | |||
