        Help with your Lens Options

Here at internetspecs.co.uk, we have kept our sunglasses lens options simple and at a great price. Because of their high overheads, high street opticians need to charge you a lot for both the sunglasses frame and any alternative lenses required. Online opticians will often make high profits on just the lenses. We have chosen to do neither! Our overheads are not high so there is no need to have our prices high - good for you!

• If you just require the original manufacturer lenses, please
   simply select 'Original Sun Lenses'. These lenses will be
   PLANO (non-prescription).

Please don't select these lenses if you require
prescription lenses.

They're scratch-resistant, hard coated lenses and have
ultra-violet (UV) protection against the sun. We usually
   whether the lenses are solid or graduated. Solid lenses
have the same shade over the whole lens. Graduated
   lenses gradually become a lighter shade; starting with a
darker shade at the top of the lens and going to a lighter
shade at the bottom.

• Our standard 1.5 Tinted Sun Lenses and our thin and
  lightweight 1.6 Tinted Sun Anti-Reflection (AR) Lenses
are ‘fixed tint’ (they are always coloured and so are for
  day use only). They will absorb 85% of sunlight. Our 1.5
Tinted Sun Lenses come in 3 different colours: brown,
  grey and green, whereas our 1.6 Tinted Sun AR Lenses
  just come in brown and grey. Our 1.6 Tinted Sun AR
  Lenses are only available from us if you have a
  negative prescription (the Sphere (SPH) reading).

• Our 1.5 Nupolar® Polarised sun lenses are tinted and
  eliminate glare, offering 100% protection from harmful UV
  rays. They're ideal for those sunny sunrises and sunsets
  when you can be 'blinded' by the sun, even while wearing
   'normal' sunglasses. Polarised lenses must not be worn
    while driving at night. They come in 3 different colours:
brown, grey and green.

•   Our 1.5 & 1.6 Transition® lenses (known as 'Photochromatic
   Lenses' and available in either brown or grey), change
  colour in sunlight, meaning that you can use them during
    the day or at night. They are temperature dependent,
    darkening better in colder climates such as Northern Europe
    (in snowy conditions, they become extra dark, due to the
   intense ultraviolet light).
   Transitions® need ultraviolet rays from daylight to darken,
   meaning they're not always suitable for behind a car
    windscreen (our Polarised lenses are good during sunny
   driving conditions - please see above). The lenses without
    anti-reflection (AR) coating are darker in sunny conditions,
   whereas with anti-reflection (AR) coating, they are better
   inside and at night because they are lighter in colour. The
   thin 1.6 Transition® lenses come with an AR coating. The
    higher lens index value (1.6) causes reflections to increase.
   Having an AR coating helps to eliminate this.

  Please note:
Our brown and grey 1.5 Transitions® have a more
  limited prescription range than we have for most of
  our other lenses.
   Certain prescriptions will require more expensive
   'surfaced' lenses. If this is the case for you, we will
   contact you very soon after you place your order to ask
       if you wish to pay the extra cost for 'surfaced' lenses or,
   if you wish to upgrade to 1.6 Transitions® or if you wish
to change or cancel your order.

• It's also possible for you to have clear lenses into the
   sunglasses frame (for those who really love the sunglasses
frame but want to have them as prescription glasses). We have
     Clean & Clear 1.6 Thin & Lightweight Anti-Reflection (AR)
Lenses* (Single Vision only). These lenses will be noticeably
thinner and lighter than standard 1.5 or 1.56 lenses.

  (You may have noticed that our Cylinder (CYL) drop-down forms
    opposite for the left and right eyes only go up to -2.00.
   However, for our 1.6 lenses, if you have a negative Sphere (SPH)
    reading, we are still able to supply, for no extra cost, CYL's
   higher than -2.00, up to -4.00. You won't be able to input this
    onto our forms so please either upload a copy of your
    prescription to us or tell us in the 'Any Additional Information'
    form).

•   Our Clean & Clear 1.67 Extra-Thin Anti-Reflection (AR) Lenses
   are even thinner and more lightweight than our 1.6 lenses. (for
   those who really like the sunglasses frame but want to have
clear lenses and use them as prescription glasses). They are
great for any prescription but are particularly good for those
who have a high prescription (sphere (SPH) reading above
+/- 2). Our 1.67 lenses are always Aspheric. Aspheric lenses
   allow the lenses to be made thinner and flatter.

  (You may have noticed that our Cylinder (CYL) drop-down
   forms opposite for the left and right eyes only go up to -2.00.
   However, for our 1.67 lenses, if you have a negative Sphere
    (SPH) reading, we are still able to supply, for no extra cost,
   CYL's higher than -2.00, up to -4.00. You won't be able to
   input this onto our forms so please either upload a copy of
    your prescription to us or tell us in the 'Any Additional
   Information' form).

•   Our Clean & Clear 1.74 Ultra-Thin Anti-Reflection (AR)
lenses are the thinnest and most lightweight plastic
lenses available (for those who really like the sunglasses
  frame but want clear lenses and use them as prescription
  glasses). They are only available from us if you have a
  negative prescription (the Sphere (SPH) reading). We
  recommend choosing a 1.74 lens if your prescription is
higher than -4.50 for the Sphere (SPH) reading (i.e: from
  -4.50 to -8). Our 1.74 AR lenses are also Aspheric which
contributes to the lenses being thinner and flatter.

•   Our 1.59 AR Polycarbonate lenses are good for sport as
     they are tougher than normal lenses. (for those who love
the sunglasses frame but want clear lenses and use them
as prescription glasses). They're know as 'plastic
     aluminium' - weight for weight, they're four times the
     strength of aluminium - the material is used for riot
   shields. Because they're 1.59, they're also thin lenses.

Please note:
Our 1.59 Polycarbonate lenses have a more limited
   prescription range than we have for most of our other
      lenses.
   Certain prescriptions will require more expensive
   'surfaced' lenses. If this is the case for you, we will
   contact you very soon after you place your order to ask
       if you wish to pay the extra cost for 'surfaced' lenses or
   if you wish to change or cancel your order.

* Occasionally, for those with a low prescription (sphere
   (SPH) reading around Plano (0) to 1) selecting a pair of
    semi-rimless (supra) sunglasses, we may have to use a
   thicker lens (1.5 or 1.56) to enable glazing to occur. Here
   is the technical bit! - for semi-rimless sunglasses, the
   edges of the lenses have to be thick enough to allow a
    groove to be cut to hold the nylon thread. On occasion,
   a 1.6 lens will be just too thin. Please be assured that
    we'll contact you before we do this to make sure you're
    happy with us using a thicker lens.

* In the instance that you have a positive (+) prescription
sphere (SPH) reading, you have a small pupillary distance
measurement and you choose a wide frame, we may
have to use a special lens (known as a ‘surfaced’ lens) to
  get the centre of the lens in the correct place. If this
  occurs for you, we will need to ask you for an additional
payment. Please be assured that if this case arises for
  you, we will contact you soon after you place your order
to ask if you wish to pay for the special lenses or if you
  wish to change or cancel your order.

Help with your Prescription

Before you order prescription sunglasses at internetspecs.co.uk, you need to have a copy of your prescription that was given to you at your last eye test. To order from us, this needs to have been within the last 2 years. If it has been longer than this time (or you have never had your eyes tested), please go to an optician and get an eye test.

After the examination, ask for a copy of your prescription - the optician is legally obliged to give it to you. Then you'll be ready to order your sunglasses from us. You can also ask the optician to give you your Pupillary Distance (PD) measurement, although he/she does not have to give you this (there may be a small fee - see our ‘Pupillary Distance' section for more on this).

On your prescription, abbreviations will more than likely be used:

• ‘R’ will refer to your ‘Right Eye’

• ‘L’ will refer to your    ‘Left Eye’

• ‘SPH’ will refer to    ‘SPHERE’

• ‘CYL’ will refer to ‘CYLINDER’

• ‘ADD’ or ‘NEAR’ refers to ‘NEAR
   ADDITION’

SPHERE (SPH)

This figure designates the strength of lens needed to correct your focus: A positive (+) SPH for long sightedness (problems focusing on close objects) and a negative (-) SPH to correct short sightedness (problems focusing on far objects). If you are neither short nor long sighted, on your prescription, you will see the word PLANO or PL, or the figure 0 (sometimes 0.00), or the sign for infinity: ∞   However, this does not necessarily mean you have perfect eyesight as you may have an astigmatism (see below).

CYLINDER (CYL)

The CYL figure helps to correct an Astigmatism - which means the eye has problems focusing at particular angles. The eye will be slightly rugby ball shaped rather than football (soccer for our American customers!) shaped. This box on your prescription MAY BE EMPTY, in which case you do not have to put anything in the ‘CYL’ part on our prescription form. Similarly, an optician may write: ‘DS’ in the CYL box. If you see this, you can ignore the ‘CYL’ part of our form.

AXIS

There will only be an AXIS figure if you have a CYL figure. It tells us where exactly on your eye the astigmatism is. Be particularly careful inputting this figure to us. It is measured in degrees from 0 to 180. Occasionally there will be a 1/2 or .5 figure.

NEAR ADDITION (ADD)

The ADD('s) is the Additional correction needed for READING and/or COMPUTER USE. The figure is almost always the same for each eye so if it is just written once on your prescription, do not be confused - you can just add the same figure into both boxes on our form.


          SOME IMPORTANT POINTS

•   Some prescriptions will include a figure in the
    PRISM section. The prism helps to correct such
    conditions as muscle imbalance problems. If
    your prescription includes a figure in the prism
    box, please get in touch with us through our
    ‘Contact Us’ page and we may be able to help
    you but it will involve an additional cost.

• Please double check you have entered the (+)
    and (-) correctly into our form

• Sometimes an optician may, for example,
   write: +050 or +175 for the SPH, CYL or the
    ADD. He/she has simply omitted the dot and
   you can enter into our form as: +0.50 or
   +1.75

• Sometimes, an optician may write the + or -
    above the figure like this: +       or this:   -
                                                     0.5                 1.5

             Help with your Frame Size

The simplest way for you to get the right frame size is to read the measurements from a comfortable pair of sunglasses (or glasses) that you already own. Often, your sunglasses will have wider lenses than regular glasses (to better protect against the suns rays) so it's probably better to read the measurements from your sunglasses. You can usually find the dimensions (perhaps with the help of a magnifying glass) on the inside of the arms/sides of your sunglasses and occasionally on the inside of the bridge (the part of your sunglasses that sits on your nose).

It is usually written in the format: 56-18-140 Thankfully, it is easy to distinguish what these numbers refer to:

• The much higher figure (140) is the Arm Length (also known
   simply as the 'Sides').
• The middle figure (56) is easily identifiable as the Eye Size (also
known as Lens Diameter).
• The much lower figure (18) will be the Bridge Size/Width.

They do not need to be an exact fit but the nearer they are to your current pair, the more likely the sunglasses you buy from us will be a comfortable fit. Please note that the Arm Length is less important in determining a comfortable fit than the Eye Size and Bridge Size are.

If you cannot identify any measurements (perhaps because they have worn away with time), you can either:

1) Visit an optical shop and find a pair of sunglasses
     (or glasses) that feel comfortable. Note down the
     measurements (ask a staff member if you are
     not sure) and come back to internetspecs.co.uk

2) Measure your own sunglasses (or glasses). Measurements
  are in millimetres so you will need a millimetre ruler:

Bridge Size:
The minimum horizontal distance between the rims on a metal or plastic frame or the minimum horizontal distance between the lenses for rimless frames.

Eye Size:
The eye size is the maximum horizontal width of either one of the lenses on your sunglasses/glasses.

Arm Length:
Measure from the dowel point (the hinge area, where the arm connects to the main part of the frame) to the furthest point of the arm. This involves measuring to the bend and then measuring the drop separately. You can then add together the two measurements to get the final arm length.

What is my Pupillary Distance (or PD)?

Your Pupillary Distance (PD) is the distance between your eyes, measured from the centre of one pupil to the centre of the other. Once we have your PD, we can then ensure that your lenses are made so that the centre of each lens lines up with the centre of your pupils. If you have a high strength prescription, (a sphere (SPH) reading higher than +/-3) a precise PD measurement is very important.

How can I find out my Pupillary Distance Measurement?

Often, your optician will not include your PD measurement on your prescription so you can ask him/her after you have had your eyes tested or get in touch with him/her at a later date (see below on getting your PD measurement from a prescription).

If your prescription is not too high, (a sphere (SPH) reading between -2 and +2) we can make your sunglasses for you using an average pupillary distance measurement.

You can also measure your PD yourself, although we recommend you have someone help you rather than use a mirror:

   • Place a millimetre ruler against your forehead and the bridge
     of your nose.
   • Line up the zero mark of the ruler to the centre of one pupil.
   • Read the millimetre measurement for the centre of the other
     pupil.
   • Repeat this 3 or 4 times for accuracy.

If your sunglasses are for reading or computer work, the measurement for your PD is always slightly less than the 'distance' PD. If you are measuring your PD yourself, the measurement you get will be for 'distance'. If you require reading or computer sunglasses, please enter your PD for distance into our form and tell us in the 'Any Additional Information' box that you measured your PD yourself. We will then adjust the PD measurement if you've ordered sunglasses for reading or computer. If you don't write anything in the 'Any Additional Information' box, we will take the PD measurement you've entered into our form as the PD required for the specific sunglasses you have ordered.

Getting your PD Measurement if it is written on your Prescription

If there are 2 PD measurements shown on your prescription, such as 63/60, this will mean that the 63mm figure is for distance use and 60mm will be your reading or computer PD.
If you have just one PD, this will more than likely be your distance PD. You may want to confirm with your optician as there is the possibility this was written with reading or computer glasses/sunglasses in mind.
Occasionally, your optician may write your PD for each eye, for example: 32/31. In this case, please write these figures into the 'Any Additional Information' box. The first figure is always the measurement for the right eye; the second figure, the measurement for the left eye.

PLEASE MAKE SURE THAT THE PUPILLARY DISTANCE (PD) MEASUREMENT YOU WRITE ON OUR FORM IS FOR THE SPECIFIC PRESCRIPTION YOU WANT US TO MAKE - WHETHER IT'S FOR DISTANCE, READING OR COMPUTER. AN EXCEPTION TO THIS IS IF YOU'RE MEASURING YOUR PD YOURSELF (Please see above, towards the end of the section: 'How can I find out my Pupillary Distance Measurement?').
