Lenses FAQs

A.

Single Vision (normal lenses)

• If you know what your Pupil Distance is, please let us know when you send us your glasses.
• If the glasses you send us already have your lenses in them, we can take the measurements from that.
• If the frame is brand new, then you could send us another frame that has your prescription in it.  We can take the Pupil Distance from the old pair. We will return both your old and new frames when completed.
• You can take a photograph of yourself wearing your glasses and we can take the measurements from the photograph. (See next question in FAQ’s)

Varifocals or Bifocals

• If the glasses you send us already have Varifocal lenses in them, we can take the measurements from those lenses.
• If the frame is brand new, then you can send us another frame that has your Varifocal prescription in them, and we can take the fitting measurements from them and return both when completed.

• You can take a photograph of yourself wearing your glasses and we can take the measurements from the photograph. (see next question in FAQ’s)

A.

We have been obtaining extremely accurate results from the following method for many years.

Before you post us your frames.

• Provide us with an image of you wearing the glasses you want us to glaze.
• Ensure your eyes are open and you are looking straight at the camera
• Don’t look up or down, or to the left or the right, straight ahead please.
• The image should be far enough away so we can check your head is in a natural position.

Once the Pupil Distance Picture has been taken.

• Email the picture to us ahead of you sending your frames so we can validate the image for Pupil Distance.
• Use the email address hello@lensology.co.uk stating your name and your address & post code.
• We will email you back and let you know that the picture is suitable. Then you can post your frames to us.

Situations where a photograph is not necessary.

• If the prescription lenses in the frame that’s being glazed are yours and you are replacing old for new there is no need for a photograph. We can take the measurements from the old lenses.
• If your lenses are Single Vision and you know your Pupil Distance already and are sure it’s 100% accurate we do not need a photograph.
• If you know your PD but your lenses are Varifocal or Bi-Focal then we still need a photograph as we need to measure the height of your pupil in relation to the frame depth.
• If in doubt send a photograph anyway, better safe than sorry.

If you are still confused, please do call us and we will walk you through the process. 

Most stock Single Vision lenses are likely to take no more than 5-7 working days which is much quicker than our competitors. If you need your glasses back more quickly you can opt for lenses from our ULTIMA range. This will fast track your lenses to within just 24-48 hours of payment. Our ULTIMA range is of the highest specification and quality and we stock thousands of lenses, covering clear lenses, sunglass lenses and Transition lenses. Our ULTIMA range of lenses also come complete with a 12 month warranty, so if you scratch or damage them we will replace them free of charge.

A. For non-stock single vision or any other type of custom-made lenses such as varifocals or bifocals, you can expect to wait up to 10 working days with the exception of mirror finish lenses which can take up to three weeks. Customers who opt for our premium best and state of the art Omni-Vision HD Varifocal will have their glasses automatically fast tracked and can expect to have them dispatched within just 4-5 working days. If you have a specific date that you need your glasses returned by, then please let us know and we will always endeavour to help.

A. Yes, we do. We supply solid tints, graduated tints, polarized tints, sun reactive lenses and mirror finish lenses. These can be supplied for both non-prescription lenses as well as prescription single vision lenses, bifocals and varifocals. If you are unsure what you have or need we can assist you, or match what is already in the frames.

SOLID TINTED

 One colour throughout the lens. The stock range colours are Grey, Green/Grey or Brown. On request we can also tint most colours like pink, blue, yellow and so on.  We can send you a colour chart to choose from.

GRADUATED TINTED

The lenses can be made to be darker at the top, gradually fading down to a light tint or clear tint at the bottom of the lens. These are all custom made and can be supplied with the same range of colour options as solid tints.

POLARISED TINTED

Polarised lenses block glare from light reflecting off the surface of water or snow better than any other type of sunglass lenses. But Polarised lenses aren’t just for sporty people and drivers. Anyone who is bothered by glare outdoors can benefit from these advanced sunglass lenses. They are custom made and available in a choice of three colours, Grey, Brown and Green/Grey.

TRANSITION SIGNATURE  8

These are market-leading lenses that turn to a dark sunglass tint when exposed to the sunshine and go almost clear when back indoors. We supply the fastest reacting lenses on the market, Transitions Signature 8. They come in Grey, Brown or Graphite Green and are available from stock in a limited power range. An extensive range is available as custom made, although these will take longer to make than the stock variety.

MIRROR FINISH

This can be applied on top of any tinted lens for an additional £35.00. Popular colours are Green, Blue, Silver and Gold. Many other colours are also available.

A.  In this case we can supply Transitions XtraActive lenses, which unlike regular Transitions Signature 8 will work well from behind the windscreen of a car. They also go slightly darker and have a quicker reaction time than Transitions Signature 8. This upgrade costs from an additional £40.00 on top of the regular Transitions lenses and is available in Grey, Brown and Graphite Green.

A. We can supply you with our specialist SmartDrive range of lenses which make driving more comfortable and safer, especially at night and in poor weather conditions. We also have a branded version that helps with this from Carl Zeiss and these are called DriveSafe lenses. The SmartDrive coating option can be applied in addition to other coating options for varifocals or ordered as a single vision product.

A. Yes, we do and it’s becoming a more and more popular option. It’s an upgrade coating called “Blue-Light Protect” and we can apply it to most of our lens options. Blue light is produced naturally by the sun but also generated by computer monitors, smartphone screens and other digital devices. Even though it does have some beneficial effects, overexposure and too much blue light at night especially can lead to vision issues, eye strain and sleeping problems. Our Blue-Light Protect range of lenses have a multi-layer design that reduces glare and reflects blue light away from the lens which helps to relieve long-term eye strain caused by modern day overuse of electronic devices. This additional protection can be added to most Anti-Glare options for just an extra £10.00

A. Yes, we supply many non-prescription lenses. We supply non-prescription sunglasses which can be made in solid, graduated or polarized tint options which can all have a mirror finish added. Many of our customers also come to us as they need plain clear lenses for wearing glasses as a fashion item. Also, non-prescription blue light filter lenses which reduce fatigue and eye-strain from prolonged screen use has become very popular over the last couple of years. Many of us here at Lensology are working on computers all day long and we swear by them.

A. Distance correcting lenses, also referred to as ‘everyday lenses’ are used by people who have trouble focusing on objects at a far distance. If you wear glasses for driving or watching TV, then they are probably distance correcting glasses. Near vision lenses which are used in reading glasses are used to correct vision for people who have trouble focusing on close up objects, such as books or a newspaper. Intermediate glasses are most frequently used by people who spend a lot of time looking at the computer screen or other such activities that are at arm’s length.

A. No, they are not. Lensology supply basic generic lenses with any required coatings, and they are perfectly acceptable and good, but we can also supply premium single vision lenses with some of the best lens coatings available. These are often made from thin, lightweight and more durable materials. For example, our ULTIMA range of lenses comes with a 12 month guarantee against scratching and damage. Our very best lenses are the type that most glasses wearers might have avoided in the past as they were so expensive, but with our extremely competitive  pricing they are now much more affordable.

A.

The stronger your prescription, the thicker and heavier the lenses will naturally be. You can compensate for this by ordering higher index lenses. How thick the lenses will be is also dependent on the dimensions of the frame you are sending to us. In our online quotations, we do recommend what we believe will be the best-looking outcome for your prescription. Higher index lenses will be more durable and lighter in addition to being slimmer.

With our ULTIMA Upgrade Offer, we upgrade your lens index to the next best option when ordering lenses from our ULTIMA-Anti-Glare range.

Lens Index

• Standard 1.5 index is basic thickness.

• Thin 1.60 High Index Lenses are on average 20% slimmer and lighter than basic 1.5 index lenses and are the minimum lens required for rimless glazing. This is because standard index lenses are too brittle to withstand being glazed into a Rimless (Frameless) type of frame.

• Thinner 1.67 High Index Lenses are on average 33% slimmer and lighter than basic 1.5 index lenses.

• Thinnest 1.74 High Index Lenses are on average 45% slimmer and lighter than basic 1.5 index lenses.

If you choose from the ULTIMA range to take advantage of the index upgrade keep in mind that ULTIMA lenses as standard come with a “no quibbles” 12 month warranty protecting your lenses against any mishaps or misfortune that may cause damage to your lenses. And to top it off if you choose ULTIMA lenses, they are made, glazed and dispatched within just 24-48 hours!

If you are not concerned with the weight and look of the lenses, we’ll still be happy to offer you the most basic lenses to suit your budget although we’ll still communicate what we think is suitable so that you can make an informed decision.
