POLICE SPL 161 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 Sunglasses Lenses'. These lenses
     will be 1.5 Polarised Sun Lenses and will be PLANO
     (non-prescription). They're scratch-resistant, hard 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 Kodak 1.5 Tinted Sun Lenses and our thin
    and lightweight Kodak 1.6 Tinted Sun Lenses are ‘fixed
    tint’ (they are always coloured and so are for day use only).
    They will absorb 85% of sunlight. They come in 3 different
    colours: brown, grey and green.
 

•   Our 1.5 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 2 different colours:
    brown and grey. 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, grey or green), 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 grey, brown and green 1.5 Transitions® and our
          green 1.6 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,
          in the case of the 1.5 Transition® lenses, if you wish to
          upgrade to 1.6 Transitions® in either grey or brown, 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 
     Kodak 'CleaAR' 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. For those
     who are long sighted (a positive (+) Sphere (SPH) reading), we
     will use 1.6 Aspheric lenses which will make the centre of the
     lenses even thinner.

    (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 Kodak '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). No matter what your prescription is, 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 Kodak 'CleaAR' 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.

*  For the rare occurrence that you have a positive (+)
    prescription sphere (SPH) reading, you have a small
    pupillary distance measurement and you choose a wide
    frame, we would have to use a special lens (known as a
    ‘surfaced’ lens) to get the centre of the lens in the correct
    place. In the unlikely event that 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. 

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

•  ‘L’  will refer to your    ‘Left Eye’   
                        
•  ‘SPH’  will refer to      ‘SPHERE’    
 
•  ‘CYL’  will refer to       ‘CYLINDER’    
 
•  ‘ADD’  or  ‘NEAR’ refers to ‘NEAR
    ADDITION’
