NICOLE FARHI NF 0017 Women's Glasses

          Help with your Lens Options    

Here at internetspecs.co.uk, we have kept our lens options simple and sometimes FREE. Because of their high overheads, high street opticians need to charge you a lot for both frames and lenses. 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!

•   We have FREE Kodak 'Clean&CleaAR' 1.6 Thin & Lightweight
    Anti-Reflection (AR) Lenses for all of our prescription glasses* 
    (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 free, 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 'Clean&CleAR' 1.67 Extra-Thin Anti-Reflection (AR)
     Lenses (at just £22 extra) are even thinner and more
     lightweight than our free 1.6 lenses. 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 Kodak 'Clean&CleAR' 1.74 Ultra-Thin Anti-Reflection
    (AR) lenses are the thinnest and most lightweight plastic
    lenses available and cost just £75 extra. 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.

•   Please select 'Frame Only' if you just require the glasses
    frame. These will be posted to you with 'dummy' (low quality
    plastic) lenses that you can easily take out (we do not
    recommend wearing glasses with dummy lenses).

•   Our 1.5 & 1.6 Transition® lenses (known as 'Photochromatic
    Lenses' and available in either grey, brown 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
    below). 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.

•   Our Kodak BluProtect lenses help to filter out blue light 
    rays that can be found in artificial light sources such as
    mobile phones and tablets. There's been research 
    showing that too many blue light rays could disrupt our
    internal body clock that controls our sleeping and waking
    cycles. BluProtect comes in standard 1.5 thickness lenses
    and thin & lightweight 1.6 lenses.
 

•   Our 1.59 AR Polycarbonate lenses are good for sport as
     they are tougher than normal lenses. 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 grey, brown and green 1.5 Transitions®, our green
          1.6 Transitions® and our 1.59 Polycarbonate lenses
          have a more limited prescription range than we have for
          all 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.

•   Our 1.53 AR Trivex lenses are impact resistant. They are
     just as strong as Polycarbonate lenses but are even
     more lightweight and have slightly sharper vision, 
     although Trivex lenses aren't as thin as the 1.59
     Polycarbonate lenses are.

•   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 3 different colours:
    grey, brown and green.

•   Our standard Kodak 1.5 Tinted Sun Lenses, our Kodak 1.5
    Tinted Sun Anti-Reflection (AR) Lenses and our thin and
    lightweight Kodak 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. They
    come in 3 different colours: brown, grey and green.
    Please note that our Kodak 1.5 Tinted Sun Lenses are not
    scratch-resistant. They are the only one of all the lenses
    that we sell on Internet Specs that are not scratch resistant
    (Kodak 1.5 Tinted Sun Anti Reflection (AR) lenses and Kodak
    1.6 Tinted Sun Anti-Reflection (AR) lenses are scratch-
    resistant).
 

* Occasionally, for those with a low prescription (sphere
    (SPH) reading around Plano (0) to 2) selecting a pair of
    semi-rimless (supra) glasses, we may have to use a special
    'surfaced' lens to enable glazing to occur. Here is the
    technical bit! - for semi-rimless glasses, 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 special 'surfaced' lens. We may need to ask for an
    additional payment for this.

*  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. 

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’
