You shouldn't order contacts with an expired prescription. You will need a valid prescription to make purchase. It is important to schedule a regular eye exam to protect your eyes and overall health.

Once you're received your new prescription, you can upload when viewing the shopping cart.

您不应订购处方过期的隐形眼镜。您需要有效的处方才能购买。安排定期眼科检查对于保护您的眼睛和整体健康非常重要。

收到新处方后，您可以在查看购物车时上传。

Unfortunately YES, you still need a valid prescription to make purchase. Even for contacts that is for cosmetic use / do not correct your vision, a prescription is required as contact lenses are medical devices. They cannot be legally purchased in Malaysia without a valid prescription.

不幸的是，您仍然需要有效的处方才能购买。即使对于用于美容用途/不矫正视力的隐形眼镜，也需要处方，因为隐形眼镜是医疗设备。没有有效处方，无法在马来西亚合法购买它们。

a. OD and OS

They are abbreviations for oculus dexter and oculus sinister, which are Latin terms for RIGHT EYE (OD)and LEFT EYE (OS).

Your prescription also may have a column labeled "OU." This is the abbreviation for the Latin term oculus uterque, which means "both eyes."

Your eyeglass prescription contains other terms and abbreviations as well. These include:

b. Sphere (SPH)

This indicates the amount of lens power, measured in diopters (D), prescribed to correct nearsightedness or farsightedness.

i. If the number appearing under this heading has a minus sign (–), you are nearsighted;

ii. if the number has a plus sign (+) or is not preceded by a plus sign or a minus sign, you are farsighted.

The term "sphere" means that the correction for nearsightedness or farsightedness is "spherical," or equal in all meridians of the eye.

c. Cylinder (CYL)

This indicates the amount of lens power for astigmatism. If nothing appears in this column, either you have no astigmatism, or your astigmatism is so slight that it is not really necessary to correct it with your eyeglass lenses.

d. Axis

This describes the lens meridian that contains no cylinder power to correct astigmatism. The axis is defined with a number from 1 to 180. The number 90 corresponds to the vertical meridian of the eye, and the number 180 corresponds to the horizontal meridian.

If an eyeglass prescription includes cylinder power, it also must include an axis value, which follows the cyl power and is preceded by an "x" when written freehand.

The axis is the lens meridian that is 90 degrees away from the meridian that contains the cylinder power.

a. OD 和 OS

它们是 oculus dexter 和 oculus sinister 的缩写，是右眼 (OD) 和左眼 (OS) 的拉丁术语。

您的处方可能还有一个标有“OU”的栏。这是拉丁语 oculus uterque 的缩写，意思是“双眼”。

您的眼镜处方还包含其他术语和缩写。这些包括：

b. SPH

这表示用于矫正近视或远视的镜片度数（以屈光度 (D) 为单位）。

1. 如果此标题下出现的数字带有减号 (–)，则您是近视眼；

2. 如果数字带有加号 (+) 或前面没有加号或减号，则您患有远视。

术语“SPH”意味着对近视或远视的矫正是“球面的”，或者在眼睛的所有经线上都是相等的。

c. CYL 

这表示散光的镜片度数。如果此栏中没有出现任何内容，则要么您没有散光，要么您的散光很轻微，实际上没有必要用眼镜矫正它。

d. Axis

这描述了不包含柱镜屈光力来矫正散光的晶状体子午线。该轴用从 1 到 180 的数字定义。数字 90 对应于眼睛的垂直子午线，数字 180 对应于水平子午线。

如果眼镜处方包含柱镜度数，则还必须包含轴值，该轴值位于柱镜度数之后，并且在徒手书写时前面带有“x”。

该轴是与包含柱镜度数的子午线成 90 度的镜片子午线。

You can divide the CYL to half and add to your SPH power. Take below as examples

Example 1:

Assume your Right Eye prescription (OD), SPH -2.00 and CYL is -1.00, then it will be -2.00 + (-1.00 / 2) = -2.50

Example 2:

Assume your Right Eye prescription (OD), SPH -2.00 and CYL is -1.25, then it will be -2.00 + (-1.25 / 2) = -2.63 << closest multiple of -0.25 (such as -2.50 or -2.75) will be the most appropriate for you based on many different considerations. Consult Optometrist for more information.

您可以将散光 (CYL) 除以 2，然后加到球镜度数 (SPH) 上。以下是两个示例：

示例 1：

假设您的右眼 (OD) 度数为球镜 -2.00，散光 -1.00，则计算结果为 -2.00 + (-1.00 / 2) = -2.50

示例 2：

假设您的右眼 (OD) 度数为球镜 -2.00，散光 -1.25，则计算结果为 -2.00 + (-1.25 / 2) = -2.63 << 根据多种因素，最接近 -0.25 的倍数（例如 -2.50 或 -2.75）将最适合您。请咨询验光师以获取更多信息。

*Generally speaking, if your ‘Cylinder’ is higher than -1.00, your Optometrist will most likely advise against using the Spherical Equivalent to order contact lenses, as the vision will be too greatly affected. Also remember that using your spherical equivalent with any amount of ‘Cylinder’ in your glasses prescription will result in some amount of blurriness. If you’re that person who cannot tolerate any blur in his/her vision, do not allow your Spherical Equivalent to be used for your contact lenses. You will not be happy with the outcome.

*一般来说，如果您的散光度数高于-1.00，验光师很可能会建议您不要使用散光转度数方程式换来配隐形眼镜，因为这会对视力造成过大的影响。此外，请记住，如果您的眼镜处方中包含任何度数的散光，使用散光转换度数方程式配隐形眼镜都会造成一定程度的视物模糊。如果您无法忍受任何视物模糊，请不要使用散光转换度数方程式配隐形眼镜，否则您肯定不会满意。
