网上买眼镜可以吗？我真的需要去看验光师/配镜师吗？

在考虑是否在线购买眼镜时，乍一看似乎更方便，价格也可能更低。但是，验光师给你的处方只是决定眼镜能否有效改善视力的众多因素之一。让我们来看看它的优缺点：

网上购物的优点：

款式和颜色选择更丰富
不同网站之间有很多选择
通常可以节省成本（稍后会详细介绍）。

网上购物的缺点：

这样你就错过了让训练有素的专业人士帮助你确保眼镜佩戴合适的机会。
就舒适性和有效性而言
为了维持你在网上看到的低价，镜框的质量控制往往会被牺牲。
具体的测量包括瞳距 (PD)、寻找最佳光学中心以及其他测量。
进步人士要么经常出错，要么无法在线购买。
与实体店相比，网上订购药品时出现处方问题的情况总体上要常见得多。
亲自

最初看似省时省钱的方法，如果出现上述任何问题，从长远来看最终可能会让双方都付出更多代价。此外，不合适的眼镜还可能导致以下常见问题：头痛、疲劳、恶心/眩晕、眼睛疲劳、眼镜容易从鼻梁上滑落，以及鼻子/耳朵周围出现疼痛/压痕。高度近视、儿童、复杂处方以及多焦点处方的人士尤其应该考虑到实体店验配，而不是在线验配。.

What does my eye prescription mean?

Eyeglass and contact lenses prescriptions can contain components and abbreviations that may be harder to decipher. Here are some of the common abbreviations and what they mean:

OD: or oculus dexter refers to your right eye
OS: or oculus sinister refers to your left eye
SPH: is the sphere and refers to the lens power required to help correct your vision. A (-) negative
indicates nearsightedness and (+) positive indicates farsightedness
CYL: is the cylinder and refers to how much astigmatism you have if any. Astigmatism is caused
by a cornea or lens that has a different shape than normal and multiple focal points.
Astigmatism is very common.
AXIS: a number between 1 and 180, indicates exactly where the astigmatism appears on your
eye
ADD: stands for the additional lens power needed to make it easier for you to read. This is seen
on prescriptions for reading glasses or the lower portion of bifocal/progressive lenses
BO, BI, BU, BD stand for base out, base in, base up, and base down. These refer to the position
of the prism on eyeglasses that correct double vision

For contact lenses you may see additional information such as the brand, mode of wear, and BC +
DIA.

BC: The base curve is the measurement that indicates the curvature and shape of your contact
lenses. This is taken when the steepness or flatness of your cornea is measured.
DIA: The diameter is the measurement of the length that your contacts need to be to
completely cover your cornea.

Are You Ready For Your Eye Exam?

拍摄者 nrd 在不飞溅

Having an annual eye exam is a great way to not only take care of your eyes but your overall health as well. Eye exams can detect early signs of conditions such as diabetes and high blood pressure. Here are some tips to help you make the most of your next visit!

What to think about:

Have I noticed any eye problems such as blurry vision, flashes of light, floaters, redness, or double vision?
Are my daily activities being affected by my vision?
How do I take care of my contact lenses or glasses
Have I had any surgeries or injuries in my eyes that I could let the doctor know about?
Any family history of eye conditions such as glaucoma?

What to bring:

Your current glasses or contact lenses even if you have multiple pairs for different tasks
A list of your medications/supplements you are taking
Have someone who can drive you home or a method of transportation ready for if you have your eyes dilated. This happens often in yearly eye exams and can make you sensitive to light and have blurry near vision (~4-6 hours)
Vision and health insurance information

Questions to ask:

Differences between contacts and glasses for you and how this compares to surgery options as well?
If anything has changed in my ocular health since the last visit?
What any symptoms you may have mean and what you can do to prevent them from getting worse or resolve?
When should I return for my next visit?

温哥华首家测量眼轴长度的验光诊所

今年一月，我们诊所用全新的“玩具”迎接了新年—— MYAH 来自 Topcon，使我们在 Eyelab 成为温哥华第一家验光诊所之一 测量并绘制眼轴长度图表.您可能想知道……轴向长度测量有什么好处？为什么我们关心眼球有多长？

随着眼睛长度的增加，我们的镜片处方量不仅会增加，而且患眼部疾病（如青光眼、白内障、黄斑变性）的风险也会增加。事实上，儿童近视的快速发展是由于眼球过度伸长所致。因此，为了监测近视管理治疗的有效性，每次随访时都会记录眼轴长度测量值，作为我们近视管理计划的护理标准。对于 Ortho-k 镜片患者，眼轴长度是用于评估近视进展的主要指标之一。
