CAT CTS 8011 Sunglasses


          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
     1.5 Polarised Sun Lenses and will be PLANO (non-
     prescription).   
     
     Please don't select theses lenses if you require
     prescription lenses.
 
 
     They're scratch-resistanthard coated lenses and offer
     100% ultra-violet (UV) protection against the sun. They're
     great for driving, especially when there's a sunny sunrise
     or sunset and you can be 'blinded' by the sun, even when
     wearing 'normal' sunglasses. Polarised lenses cannot be
     worn while driving at night. We usually specify 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. Please only order these Polarised
    lenses if you want to have prescription lenses or if you
    want to have the anti-reflection (AR) Polarised lenses.
   
This is because the original manufacturer lenses already are
    1.5 Polarised, but are not anti-reflection (AR). 

 

•   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). O
ur 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?').
