Glasses FAQ


 

What should I keep in mind when I buy a pair of glasses?

We have compiled the key points for purchasing a pair of glasses for you in the following check list.


1. Frame and color which harmonize with your face shape

A pair of glasses should underline the natural shape of your face. In addition to color, brand and style, choose a frame which suits your face shape as well as your type. We will show you how it works.

 

2. The size of the glasses

Just as important as the frame is the size of your glasses which has to match your face.

You can find out more about the ideal glasses size by following this link: Which glasses sizes are available?

 

3. Shortsightedness

Shortsightedness requires lenses which are stronger than those needed when you are farsighted. If you are extremely shortsighted, choose a strong frame which embeds the glass thickness as well as the frame in an optimal way. Plastic frames are particularly well-suited for this purpose. Rimless glasses or glasses with metal frames emphasize the thickness of the glasses and can be inappropriate. If you still don’t want to dispense with thin lenses, try using glasses with a refractive index. For further information on this topic, follow What do I have to keep in mind concerning eyeglass lenses?


4. Farsightedness

If you are farsighted, you have the advantage that convex lenses are generally narrower. They adapt to the frame in an ideal way, no matter whether you opt for a thick frame or a more delicate one.

 

5. Allergy

Are you allergic to nickel? If so, it would be best to choose a frame which is made of plastic or titanium.

Which dioptries do I need?

Depending on your type of defective vision, the following values can be necessary for an order. You can find these values in your glasses pass or in your glasses prescription.

 

Axis

In your glasses pass or your glasses prescription you will find the axis value, indicated by >>A<< or >>Ach<<. The axis value lies between 0° und 180° and provides information about the adjustment of the cylinder for the correction of the warping of the cornea (astigmatism).

 

 

Addition (only for progressive lenses)

Addition >>Add.<< indicates the strength of the lenses which is needed not only for the correction of farsightedness, but also for your immediate surrounding. This value is also referred to as immediate value and supports sharp vision, for example when reading. Addition means that close-range values and distance values are added together in order to calculate the close-range value.

 

 

Pupillary distance

The pupillary distance >>PD<< measures the distance between the center of the pupil and the center of the bridge of the nose. The pupillary distance of the right and the left eye is determined separately and is given in mm. You can find the pupillary distance in your glasses pass. If you find only one value in your glasses case, you can divide it by two and write down the new value for the left and for the right eye. However, you can also measure the pupillary distance on your own: Instruction for measuring the pupillary distance.

 

 

Sphere

The sphere is abbreviated with >>Sph.<<, >>Sphär<<. or >>S.<< and describes the lens thickness. The “+” sign indicates farsightedness (hyperopia, hypermetropia) and the “-“ sign indicates nearsightedness (myopia). If there is no sign available, it is always a “+” value. If a value is marked with the sign “F” or “distance” it refers to distance glasses. The signs “N” and “vicinity” are used for reading glasses.

 

 

Cylinder

The value of the cylinder is often abbreviated with “Zyl.” Or “cyl.” and specifies the strength which is needed in order to correct the warping of the cornea. Please do not forget to enter the “+” or “-“ value prior to entering the cylinder value before you submit your order.

What do I have to keep in mind concerning eyeglass lenses?

The glass type of your glasses contribute considerably to your appearance and to the weight of your eyewear model. The color and polarization of the lenses can also play an important role, as is the case with sunglasses and sports glasses.

 

MrLens offers high quality synthetic lenses, which have the great advantage that they are light-weight and resistant to breakage. The smooth surface of the synthetic lenses is refined with hard coating which protects them from scratches. Due to Anti-reflective coating on the glasses, light reflection can be prevented. The refractive index of your glasses is crucial, because it determines the glass thickness. For further information on this subject, read Which types of glass thickness are available? Which type of glass thickness is right for me?


We are glad to help you if you have further questions on this subject. You can contact us by telephone 041 741 28 87 or you can write us an e-mail.

Can I order non-prescription glasses?

Sports glasses and sunglasses are popular accessories and daily companions. They are often non-prescription glasses. MrLens offers not only lenses for the correction of sight defects, but also so-called plane glasses without a prescription. If you would like to have plane glasses, simply type >>0<< into all values such as axis, cylinder, etc. and leave out the section for the papillary distance (PD). To avoid any misunderstandings, you can also send us an additional note along with your order.

 

We are glad to consult you concerning the topic of plane glasses by phone 041 741 28 87 or you can simply write us an e-mail.

My MrLens glasses do not fit properly. What should I do?

The glasses models which MrLens provides are well adjusted before they are delivered. This adjustment usually ensures a perfect fit. If your glasses are still uncomfortable or don’t fit properly, an optician can immediately customize them by making a few quick adjustments of the frame. Please do not bend the frame yourself, because it could cause damage.

 

Do you have any further questions concerning the proper fit of your glasses? We are glad to be at your disposal anytime. You can contact us by dialing 041 741 28 87 or you can send us an e-mail.

What types of lens thickness are available? Which type of lens thickness is right for me?

The lens thickness of your glasses is decisive for its weight and its optical appearance. Synthetic lenses are produced with a different refractive index. This refractive index contributes significantly to the lens thickness as follows: The higher the refractive index, the narrower the glass.


 

We recommend to you the following glasses index according to your visual deficiency:

 

Defective vision up to ±2,00 dioptries

If your visual deficiency is moderate, you can use standard glasses which have a refractive index of 1,50.

 

Defective vision between ±2,00 and ±4,00 dioptries

If your visual deficiency is in this category, we recommend that you use thin lenses with a refractive index of 1,60.


Defective vision between ±4,00 and ±6,00 dioptries

We recommend that you opt for thin lenses with a refractive index of 1,67 if your visual defect is located at ±4,00 or more.

 

Defective vision ranging from ±6,00 dioptries onward

If you have a strong visual defect, we recommend that the lenses you choose for your glasses have a refractive index of 1,74.

Which glasses sizes are available?

In addition to the shape or color or your glasses, it’s important that the size of the glasses fits your face. At MrLens you can find various measurements that give you information about the size of the glasses:

 

A = Width (total width of the frames)

B = Nose bridge (distance between the lenses)

C = Lens width (horizontal width of a lens)

D = Lens height (vertical height of a lens)

E = Length (side length)

 

Determine the optimal rim size

In order to calculate the rim size of the glasses, simply add together the width of the nose bridge (B) and the lens width (C). By means of the rim size you can find out whether a pair of glasses is an optimal fit for your face and whether the pupils look through the geometric centre of the glasses. Rim sizes that are approximately equal to or slightly larger than the interpupillary distance are ideal. You can find out your interpupillary distance in your glasses pass under the heading of >>IPD<< or you can measure it yourself.
