    Here are some answers to commonly asked questions regarding our optical products

    How are Signature range glasses different to the other products?

    One of the hallmarks of the Signature, Sunreaders and Sunglasses ranges of glasses by On the Nose is the material they are made from.

    Most commonly available plastic reading glasses are polycarbonate. It is a strong light plastic but it is very brittle and breaks if bent too far. The Signature Range of OTN glasses are made from CP (or Cellulose Propionate). It is a hypoallergenic, extremely clear, strong and flexible plastic.    It is
    reknowned for it’s substantial look and feel. It is so flexible, it needs to have a wire inside the temple. This means that the frame can be bent and twisted to fit one’s face exactly. It is also a thermoplastic, which means that with the application of heat, temples can be shaped for a perfect fit and lenses can be popped in and out with relative ease.

    This does make the frames very suitable for use with a prescription lens, which many customers have chosen to have fitted by their optometrist.

    CP is made from Cellulose, a material which we get from trees and grasses. The CP in On the Nose frames comes from softwood plantation timber - a completely renewable resourse. For every two trees consumed in the production of these resins, three are planted. It is completely environmentally sustain-able.

    Not only are they environmentally CO2 negative, but they last much longer than Polycarbonates made in environmentally unsustainable ways using nasty chemicals and containing the controversial BPA. In many ways glasses made using CP are the Green solution to the problem of Presbyopia.

    If in doubt about the type of plastic used on a glass, look inside the temple (if it is clear), and see if it has a wire - if it does it is either Cellulose propionate [known as CP] or Celluloase Acetate [known as Acetate] - both are clean and green!

    Can I put my prescription lenses in your frames?

    The short answer is yes - but it depends which frame you choose. In general, the Signature Range glasses, specifically those made from CP (see above) are suitable. This is because CP frames become more flexible with heat and lens can be made to fit snuggly.

    Some metal frames are also suitable where they have a screw fit frame which can be tightened to firmly hold a lens.

    Polycarbonate frames are generally not suitable unless you have your lenses specfically cut for this style of frame. They utilise a snap fit lens which is held in place by a ridge of lens on the edge. Mnay lens cutters and optometrists may be reluctant to make and/or fit these lenses, where the lens is an expensive prescrition.

    My glasses are crooked. Are they faulty?

    People will often place a pair of glasses on a flat surface and decide that they are not straight because they do not sit flat.    This may be an
    indication of them being uneven, or it may not. Glasses are not meant to sit on a flat surface so it’s not really a good test.    What is important
    is that they sit comfortably and straight on your customers face. Not everyone’s ears, eyes and nose are completely straight or level. The good thing is that glasses can be adjusted to fit all these different faces.

    If they are not straight it could be that they were not manufacturerd straight, or it could be that the arms were crossed in an unusual way or the frame was put under some pressure accidentally in storage or in transit. Both may be able to be corrected.

    Plastic Frames
    The place to bend plastic frame glasses is at the bridge. Grasp one lens in each fist and twist gently but firmly to correct the twist.    Often this will be enough.

    Metal Frames
    Usually these become bent at the hinge due to squashing whilst folded. Correction can be difficult but sometimes gentle bending of the temple, whilst grasping the nearest lens will correct alignment.

    Don’t worry if the glasses break while performing this operation. It is better to replace a pair having tried to repair them, than to have
    replaced them without trying.

    My lens has fallen out.

    A firm push, or the wrong sort of twist can be enough to loosen or dislodge a lens. Unless the frame has been damaged it is quite possible to put the lens back in by pushing it firmly in. Start by fitting the edge closest to the bridge in position and work along the top edge until the whole lens fits into place. If you cannot get it back in we will happily replace the whole pair of glasses.

    What does polarised mean?

    Polarised refers to the ability of the lens to block reflected light from horizontal surfaces. See our blog story for mor details.
