눈 검사 및 안경 처방전 읽는 방법

미국에 거주하는 중국계와 유학생의 경우 적합한 안경을 사는 것은 쉽지 않습니다. 한편으로는 외국 안경은 아시아인의 얼굴에 맞지 않으며, 다른 한편으로는 검안 절차가 더 복잡하여 중국의 어떤 안경점에서도 예약 없이 검안을 받을 수 없습니다. 이 글에서는 미국에서 눈 검사를 하는 방법과 처방전을 읽는 방법을 알려드립니다. 더 이상 검안을 걱정할 필요가 없습니다.

눈 검사는 어디에서 할 수 있나요?

소매점
안과

미국에서 시력 검사와 처방전 작성은 두 가지 별도의 절차입니다. 따라서 안경을 사는 첫 번째 단계는 시력 검사입니다. 하지만 많은 사람들이 눈 검사를 어디서 해야 할지 모릅니다. 특히 미국에 처음 온 사람들은 더욱 그렇습니다. 일반적으로 소매점이나 안과를 선택하여 눈 검사를 받을 수 있습니다. 두 곳 사이에는 몇 가지 차이점이 있습니다.

Retail stores

Retail stores like Costco, Sam’s Clubs, Walmarts, and more will offer an optical center for eye exams. The average cost of prescription glasses is about $50, and the cost of contact lenses and glasses together is about $100. And if you don't have serious eye disease and just want to do optometry, then you can choose an optometry center in retail stores to do an eye exam. The price will be cheaper and more convenient.

Eye clinic

If you have eye diseases like Dry Eye, Glaucoma and so on or you want to prevent ocular diseases then you better choose an eye clinic. Because Ophthalmologists are more professional than optometrists， there are also more eye tests included. But it should be noted that the cost of the eye clinic is higher than retail stores. The average cost of an eye exam is about $200.

Regardless of whether you’re visiting a chain or an eye clinic for your exam, make sure you know what the pricing structure is before committing to avoid any surprise costs.

How to read Eyeglass Prescription?

After you have done your eye test, you can get your prescription, there are generally two types of prescriptions, one is a prescription with only frame glasses; the other is a prescription that includes both frame glasses and contact lenses. First, we’ll show you how to read eyeglasses prescription.

• OD &OS&OU

OD( oculus dextrous) means right eye, sometimes doctors will use RE of right instead of OD; OS( oculus sinister) means left eye, sometimes doctors will use LE of left instead of OS; OU(oculus uterque) means both eyes. They are all Latin abbreviations.

• Sph(spherical)

The degree of myopia or hyperopia, the negative number is myopia, the positive number is hyperopia and multiplied by 100, it becomes the Chinese degree. For example, -2.50 is 250° myopia.

• Cyl: (cylinder)

In astigmatism degree, a negative number is a myopia, a positive number is farsightedness, and multiplied by 100 becomes a Chinese degree. For example, -2.00 is 200° of astigmatism.

• Axis (astigmatism)

The number of axes describes the location of astigmatism in your eye. The smaller astigmatism, the demand for axial astigmatism error is low; the larger astigmatism, the demand for axial astigmatism is high.

• PD ( pupillary distance)

In short, it is the distance between the pupils(black hole) of the eyes. The parameter of pupillary distance is very important in Optometry. Once the measurement of pupillary distance is inaccurate, it will affect the wearer, causing the feeling of discomfort and may even affect the vision. If you can’t find your PD on the eyeglasses prescription, you can use our online tool to measure pupillary distance by yourself.

• Prism

Prisms generally correct and relieve strabismus; for people with nearsightedness or farsightedness, this parameter will not appear on your prescription.

• Add (additional magnifying)

Add means additional magnifying. This column is seen on prescriptions for reading glasses or the lower portion of bifocal or progressive lenses.

Contact lenses have many advantages over frames. Therefore, many people with myopia have replaced frames with Contact lenses. However, when choosing contact lenses, many people have misunderstandings. They directly use the eyeglasses perspective to buy contact lenses, which causes an increase in myopia. The degree of contact lenses is not the same as the frames. Because the contact lens is attached to the cornea, the distance of light refraction is shorter, and the smaller the degree of a concave lens, the faster the refraction distance of light, so the degree of Contact lenses is smaller than the frames. There is some difference between eyeglasses prescription and contact lens prescription, to find a contact lens that suit you, we’ll tell you how to read your contact lens prescription.

How to read contact lens  Prescriptions?

• OD/OS/OU

Same as an eyeglasses prescription, referring to the right eye/left eye/both eyes.

• Power/SPH

 Same as eyeglasses prescription, referring to luminosity, the negative number is myopia, and the positive number is presbyopia.

• BC

BC  is  the  abbreviation of "Base Curve", lens base curve (according to the corneal curvature)

DIA stands for "Diameter", lens diameter (based on corneal diameter)

• Brand

The brand of contact lenses that your doctor recommends for you is based on the condition of your eyes.
