你知道近视眼是怎样形成的吗？3大因素供你参考！
生活中令人后悔的事不少，谈及近视，想必大部分人都会后悔没有保护好自己的眼睛，从此与眼镜相伴。
戴眼镜是治疗近视的主要矫正方法之一，但是却会给人带来诸多不便。如果时间能倒流，知晓近视原因的你，还会放任自己不注意用眼吗？当然，近视眼的形成原因不一，我们需要了解这三方面因素。
一、遗传因素
据相关研究表明，近视眼有一定遗传倾向，尤其是高度近视。如果父母双方均患高度近视，那么遗传率大大的提高，通常来说，父母只有一方患近视眼的遗传几率会较高。但是，如果父母是一般近视，那么遗传倾向就不很明显。有遗传因素者，患病年龄较早。
二、发育因素
发育因素也是引起近视眼的主要原因之一，对于婴儿来说，其眼球较小，通常来说他们都是远视。但是，随着年龄的增长，眼轴会慢慢地加长，大多数到了青春期时就会发育正常，这是眼睛的正视化一个正常的过程。
需要大家注意的是，在正视化过程中，由于各种因素的影响，通常会导致眼睛接收到很多种异常的视觉经验，或者长时间不良的用眼习惯，都有可能造成眼球过度发育，让眼轴增长，从而引起近视。
三、环境因素
环境因素是引起近视最为主要的原因，据相关研究表明，长期近距离用眼，那么就会让眼眼睛趋向近视发展。
除此之外，户外暴露时间足够长能有效的降低近视的发生率，由此看来，光照强度会间接或者是直接近视的发生与发展。因此，在日常生活中大家一定要注意用眼环境和用眼卫生，这样可以预防近视发生。
近视眼形成的三大影响因素，你了解了吗？近视眼的发生给大家的生活带来很多不便，在了解了近视眼形成的原因之后，要尽量的避免这些因素发生在自己的身上。
