Eyeglass Fitting

I'm concerned that while my prescription may be filled correctly, there was an assumption as to the angle at which they would sit on my face. When I take the temples from behind my ears and place them to the outside of the ears, the glasses can sit at at different angle. Things look better at this angle.

Has anyone corrected for ears that are too high?

Optical lenses work best when the wearer has a small amount of pantoscopic tilt to the frame. Pantoscopic tilt means that the bottom of the frame tilts slightly closer to the face than the top of the frame. BUT, excessive pantoscopic tilt can adversely affect the optics of your eyeglasses. Put your glasses on and have someone stand to the side and look at how the frame fits your face. Have them visualize an imaginary line formed by the lens in your frame. That imaginary line should be slightly different than an imaginary line drawn through the front of your face. The frame's imaginary line should be SLIGHTLY closer to the face's imaginary line at the bottom. If the frame is angled too severely inward at the bottom (which could happen if your ears are somewhat higher than most) then you need to have the frame adjusted to reduce the amount of pantoscopic tilt. This is done with a tool called a temple angle plier. The plier is used to reduce or increase the pantoscopic tilt on a frame. Sounds like this is probably what you need to have done. Hope this helped.

I found a pair of reading glasses I like for about $10. Could I bring these frames somewhere and have them fitted with my prescription? If so, where should I look, and how much can I expect to pay?

But before I buy the frames, would this ultimately be a waste of money? I imagine $10 frames probably aren't the most durable in the world, I just feel like I'm being ripped off at the the big chain frame stores.

Thanks

You shouldn't waste your money on those frames since they weren't made to handle the use they'd get once they were your everyday glasses. Ask your friends who wear glasses where they got theirs. We found a great place to get 2 complete pair for $100. For single vision basic glasses. It's a great place to get glasses for kids since they sometimes break or lose glasses. It costs a bit more for bifocals or glare free, but it's still cheaper than the big mall chains. I know what you mean too about the bigger chains, you go in expecting $100-$150 and come out $250-$300 in debt! Good Luck! 8-)

I want to buy some hand painted frames online. Would I be able to take them to an eyeglass provider and have them give me an eye exam, and fit the lenses to my frames?

They should easily be able to make lenses for your frames. Just be ABSOLUTELY CERTAIN the frames are the correct size or you could get really bad headaches from the lenses being in the wrong position.

Price: $29.75

What I mean is what do they do to the glass so it fits your prescription and how does a prescription for a far-sighted person differ from the prescription for a near-sighted person when it comes to making the lens?

Most plastic single vision lenses in the lower powers are moulded to precise curvatures with the powers already in them. The optical labs buy lenses like that already made , then we just line them up in the lensometer to find the optical centers, and the axis, then cut them for the frame. Most single vision lenses range from 60 to 72 mm across, and are round. They are known as "stock lenses "

All bifocal lenses are ground with special machines called generators . The blanks they use come in predetermined base curves , and the front surface is already moulded, so it is never touched. The back surface of the lenses are ground down to specific curvatures to give the prescription required. Then they are polished on the back surface in 2 different machines, before being ready to cut into the frame. That is the same process for single vision lenses that are out of the " stock lens " range.

The generator is kind of like a lathe with diamond cutting blades, that is mostly controlled by computers now.

The prescriptions can be ground in negative powers for nearsighted, or positive powers for farsighted and presbyopia. Any astigmatism corrections are done during the grinding process also.

Note, the front surfaces are never ground or polished, they are all pre-moulded blanks. That's why scratches can't be removed.

There, now you are ready to go make lenses....

I'm pricing eyeglasses for the first time in many years and I cannot get over the fact that they cost 100, 200 300 and sometimes much more. I know they are made to be adjusted in different places, but they are just plastic and metal. Then the lens price is added on and that's crazy expensive, too. After an eye exam, contact lens fitting/purchase and eyeglass frames and lenses - a person could spend $700 to $1000. Why?

these are all MY OPINIONS...but...there are multiple reasons:

1) the cost of multiple "remakes" and "warranty" replacement is built into the cost of the frame & lenses. something like 15% of all glasses purchases have to be re-done or totally replaced for one reason or another. most of the "warranty" replacement really shouldnt be "warranteed". its patients driving over their glasses, sitting on them, etc etc but they gripe enough that we have to take it back and replace it for nothing.

2) there is no money in contact lens sales anymore

3) there is not very much money in examination fees anymore

so of you buy glasses at a private practice, you're paying for the doctor's student loans, staffing, rent, overhead, materials, expensive equipment, etc etc etc with your glasses purchase. for the record i drive a 1999 dodge pickup, not a lexus or anything ;)
