O'NEILL ONS 'ENSENADA 2.0' 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-resistant, hard coated, anti-reflection
     (AR) lenses and offer 100% ultra-violet (UV) protection
     against the sun. They're Hydrofreak™ lenses which are
     sealed and protected from water damage by adding a 
     repellent hydrophobic coat. They are made from impact
     resistant polycarbonate. 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. This is
    because the original manufacturer lenses already are 1.5
    Polarised. 
 

•   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. 

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

•  ‘CYL’  will refer to       ‘CYLINDER’
