How To Clean and Care For Eyeglasses

Please keep your eyeglasses clean by washing them in warm soapy water or with the supplied lens cleaner. Rinse well and dry with a soft lint-free cotton towel or special eyeglass cleaning cloth. Do not use cloths washed with fabric softener and never use ammonia or acetone based products.

Don’t wipe your dry lenses with tissue paper or paper towel (paper fibre products will scratch lenses). Always use the proper micro-fibre cloth and cleaner to remove any dust and smudges off of the frame and lenses. Make sure to wash the cloth regularly.

When not wearing your eyeglasses, keep them in their protective case. Never rest them face down on their lenses. Always remember to use both hands to take off and put on your glasses. Grab the temples midway on each side and slide them over your ears. This will help keep their adjustment longer.

However, over time, your frames will need adjusting. While many people like to think they can adjust their frames by themselves, it is recommended to have an eye care professional adjust your eyeglasses to ensure the proper fit and comfort. As part of our promise to you for as long as you own your glasses, you may send your glasses to us for cleaning, free minor repairs and adjustments.

General Frame Selection Guidelines

Whether it is your first or next pair of glasses, you need to be an expect in choosing your best eyeglasses. Remember eyeglasses are no longer for prescription purposes only. It is also a fashion apparel. Though frame styles frequently change, these general guidelines for selecting eyewear always apply:

  • Eye position
    Regardless of the shape of the frame, your eyes should be centered within the lens openings of the frame.
  • Width
    The frame should be wide enough so there is just slight clearance between the frame temples and the sides of your head.
  • Brow
    The top of the frame eyewire should follow (but not cross) your brow line, and should not be noticeably higher or lower than the brow lines. If you have thick eyebrows, consider a thicker, darker frame for balance.
  • Proportion
    The size and weight of your eyeglasses should be in proportion to your body size and weight. if you have a slim or petite build, choose thinner, more delicate frames for a balanced look.
  • Bridge
    Pay particular attention to the fit of the bridge and maximum weight distribution on acetate frames or frames with no nose pads. Also, avoid wide bridges on low or shallow noses.
  • Eye size
    The outer edge of the frame should be even with the widest points on the head (usually just above are ears). The eye size is also contingent upon the Rx and so it is not necessarily correct to put a large frame on a large person.
  • Eyewires
    Long shapes, though sometimes stylish, can be poor lens holders. This is especially true with plus lenses because the higher base curves cause the eyewire to lift off the lens and pop it out. Eyewire barrels that protrude can also be a problem with heavier lenses, which require more tension and usually leave a gap in the eyewire.
  • Lenses
    Thinner, lighter, reflection-free lenses are always the best choice. Choose high index plastic lenses with anti-reflective (AR) coating for the most flattering appearance. If you have a bifocal prescription, choose Progressive lenses to avoid old-fashioned bifocal lines.
  • Endpiece
    Since most of the adjustments on a frame are done with this area, care must be taken to ensure that any adjustment necessary for client comfort can be made in the future, including:
    • pantoscopic and retroscopic tilt
    • temple spread or inward movement and the ability to rotate
    • for proper temple fold
  • If the lenses are very thick on the temporal edge, the end-piece will need to be long enough to allow the temples to close without touching the lenses.
  • Hinge
    The hinge should be appropriate for the weight of the eyewear. A spring hinge may not be able to apply enough pressure to the mastoid area to prevent the eyewear from slipping
  • Temples
    Solid block end pieces are very limiting in their adjustment but are also among the strongest. This goes to show that with a good initial fit, adjustment limitations are not always a bad thing. When selecting temples, make sure they can be curved inward slightly just after the widest point of the head. Temples that are too short will cause problems. Make sure there is enough space between the temple and the back of the ear.

Parts of An Eyeglasses Frame

The first step in finding the perfect pair of eyeglasses is knowing how they work! If your glasses are too tight, too big, or don’t sit on your nose correctly, this diagram can help. Take a look at our detailed glasses diagram below and read more about each frame part below the main image. Knowing the parts of your glasses will help you find a pair that not only improves your eyesight, but that will fit well and look great, too!

  1. Temples – The temples are the long arms on the side of the frame that fit over your ears for a snug fit. Temple length varies and plays a factor in the fit of a frame.
  2. Hinges – Hinges, just like those on a door, are the part of glasses frame that allow the glasses to fold inwards. Spring hinges in eyeglass frames allow for the best fit flexibility in a frame, as the spring temples can hyperextend beyond 90 degrees.
  3. Lenses – Eyeglass parts which hold a wearer’s prescription. Lenses commonly come in clear plastic or polycarbonate. Fully magnified, bifocals, multifocal, reading sunglasses, and blue light lens types are all found on NunaEyecare.com.
  4. Nose Pads – The nose pads are the round plastic pieces under the bridge that sit on your nose. They give your glasses a more comfortable and secure fit. On metal frames, nose pads are plastic, while most plastic frames have built-in nose pads.
  5. Top Bar – Some glasses also include a top bar (or brow bar), which is placed above the bridge between the lenses. It is used for stability and also for clip-ons (and the clip-ons attach to the top bar).
  6. Bridge – The arched portion of the front frame that rests on your nose and joins the two rims together.
  7. Pad Arms – Adjustable pieces attached to the frame on one end and the nose pad on the other.  They allow room for adjustment so the glasses fit the wearer’s natural face shape. Note: not every frame has pad arms; they are most commonly found on metal frames.
  8. Temple Tips – Plastic pieces that cover the temple ends where the temples rest behind the ears. They provide extra comfort to the wearer, especially on glasses with metal frames. Also referred to as earpieces.
  9. Screws – Small metal or plastic pieces inserted into the hinge to connect the temple to the frame’s end piece. Screws may also be found on the bridge to hold nose pads in place.
  10. End Pieces – These are placed at the corners of the frames and act as a connector between the hinges and the front of the glasses.
  11. Rims– Also known as eye wires, this is the front portion of a metal frame where lenses are inserted and held in place.
  12. Bifocal – Our bifocal reading glasses have unmagnified lenses which also contain inserts with the magnification of your choice in the lower portion of the lenses.
