Eyeglasses Frequently Asked Questions

1. How do I know if the frame size fits me?
  Different frames are in different sizes. You can find the frame sizes on our website, incl. frame width, lenses width & height, bridge, suitable papillary distance, etc.
  Then refer to your previous glasses, check the inner temple arm and there may be some numbers there.  The first number is lens width, the second is bridge and the third is temple. If you don’t find the numbers on the inside of your frame, you can always try measuring it by your hand. And then choose frames with same or similar figures.

2. What are the best frames for my face shape?
  Generally speaking, you can stick to this one principle that’s the one that contracts with your face shape.
  If you have a square face, you can choose an oval or round frame, if you have an oval or round face, you can choose a rectangular frame, and if you have a heart-shaped face, aviator glasses or wayfarer glasses are your smart choices.

5. Can I use my contact lenses prescription to order glasses?

  We’re very sorry to tell you that a contact lenses Rx only can be used for contact lenses.


6. Why are the lenses so thick?
  The final lens thickness depends on the strength of your prescription, the size of your frame, and your personal measurements. Fortunately, recent innovations in lens designs and materials have made lenses thinner by up to 60% in some cases. If lens thickness is a concern for you, notify the optometry staff member; he or she will help you select a frame and lens that allow you to use a thinner lens.


7. What does the Lenses Index numbers mean?

  The Lens Index number (1.51, 1.59, 1.61, 1.67, or 1.74) refers to the degree of refraction the lens provides. This means how much light that enters the lens is refracted (bent) as it passes through the lens. Lens Index is also related to the thickness of the lens. The higher the index, the thinner the lens will be. People with higher prescriptions should choose high-index lenses.


8. How often do i need to get new eye glasses?
  This depends on a number of personal factors, such as changing needs, tastes or lifestyle, but you should visit your eye doctor at least once each year. If you notice problems with vision or headaches, then it’s best to consult your doctor right away for a full evaluation and new glasses, if needed.


9. How can I tell if I need bifocals?

  Bifocals and progressive lenses are most often prescribed for presbyopia in those over age 40 and for individuals who have trouble seeing clearly both at a distance and when reading. Bifocals can also help a person who over-crosses his or her eyes when viewing close objects. An eye exam with a qualified eye doctor can assist you with determining whether bifocals are right for you.


10. Instead of bifocals, can I use progressive lenses and choose a smaller eye glass frame?
  Yes. Progressive lenses offer more precision in your viewing range within a smaller lens diameter. However, some frames are too small for a proper fit; a trained optician can work with you to find a frame that is sized correctly for both your lens and your face shape.


11. Will I have to wear eye glasses forever?

  Unfortunately, you probably will unless you elect to use contact lenses or corrective laser eye surgery. The great news is that there are lens and surgical advancements in optometry everyday.
