Frames for Glasses Lenses
Most frames for glasses work with most lenses. There are some exceptions, however, at Eyeglasses.com we will not make a frames for glasses that we do not think will work well. You are better off not studying the exceptions, and just looking for the frame you want.
However, if you are interested to learn more about frames for glasses, and some of the frame/lens combinations that do not work, then read on.
If your prescription is under +/-4.00 sphere, your lenses will work in almost any pair of frames for glasses. If your prescription is stronger than +/-4.00 sphere, or if you want multifocal lenses, there are some additional considerations to make in your choice of frames for glasses.
If your prescription has a minus sphere (like -4.00, -4.25, or more), hard resin lenses will be noticeably thicker. In this case, you can go to a thinner, more expensive lens material. If you prefer hard resin, you should look for thicker frames for glasses in order to cover up some of the edge of the thick lens, and avoid thin metal frames that will accentuate thick lenses. Thick lenses are also thicker when wider or taller: you should stick to smaller eye sizes because the bigger the lens size, the thicker it gets at the edge.
If your prescription has a plus sphere (like +4.00, +4.25 or more) you do not need to avoid thin frames since plus sphere lenses are thicker in the middle and thinner at the edge.
If you do have a strong minus correction, you should also consider purchasing a thinner lens product, like a high index lens and/or one with aspheric design. Also, rimless frames for glasses constructions are not recommended for thick lenses because the heavy lenses often cause the frames to be top-heavy and can slide down your nose more readily, and can loosen up over time.
For multifocal lenses (progressive, bifocal, and trifocal), there needs to be enough height to the frame (known as the B measurement) so that the viewing areas are large enough to see through. We recommend that the B measurement be at least 30mm for any frame that will be getting multifocal lenses.
If you have fallen in love with frames for glasses that has a B measurement of 27mm to 29mm, there are some new short corridor lens choices that may work for you.
Choosing eyewear for children
The most important issues in choosing eyewear specifically for children are safety, durability, cost, and will they wear it?. Regarding safety, children should only wear polycarbonate lenses. Cost and durability are related; you should not pay a lot for children’s frames for glasses as kids are likely to damage, lose or outgrow them. To limit these problems, look for spring hinges that allow for some flexibility and help to avoid breakage at the temples. Stronger frame materials like titanium or flexible frames will last longer, but generally cost more. You may want to buy two pairs of cheaper frames for glasses and lenses instead of one pair of expensive frames.
If your child is very active, you should consider cable temples that hold the frames for glasses to the ears better, but can also be annoying and painful behind the ears. Finally (and most importantly) your child is more likely to wear the frames for glasses if he/she likes them.
Shopping for frames for glasses online for children is difficult because of the special considerations for smaller children. Take them to the store with you and let them help you choose the style and color (and cartoon character!) that appeals to them.
There are many different types of prescription glasses that are out there. For example, there are rimless eyeglasses, titanium eyeglasses, plastic eyeglasses, and flexible eyeglasses. You can also get eyeglass frames with sunclips – clip on sunglasses attachments to turn regular eyeglasses into prescription sunglasses.
