What’s involved in making eyeglasses?
Once your eye doctor determines your prescription, the lab just makes your lenses, right? No, there’s much more that goes in to the process of making your new eyeglasses. There’s frame selection, lens design such as single vision, bifocal, or progressive lenses. There’s the choice of material for the lenses and the frames. There are issues to determine such as tinting, polarized lenses, adjustable tints, glare-free coatings, scratch resistance, UV protection, and safety concerns. And then there are measurements to determine how best to fill your prescription. These measurements include:
- Frame size. Not only does the frame need to fit your head, it needs to fit the bridge of your nose so it won’t slip. The frames have to be large enough to support your vision needs as well. For example, if you’re ordering a progressive no-line bifocal and the frame is too small the reading portion of the lens may be cut off when edged down to fit the frame. Now you have eyeglasses you can’t use.
- Temple size and shape. The temples are the part of the eyeglasses that fit behind your ear. If they’re too long, the glasses will constantly slide down your nose. If the temples are too short, they’ll hurt behind your years irritate the skin.
- Pupillary Distance. This is the distance between your pupils. This measurement is needed so that the lenses are centered properly in front of your eyes. If this measurement is off, even by a single millimeter, you can have eye strain, headaches, and vision that is not comfortable.
- Seg Height. That’s optician speak for where a bifocal or progressive lens needs to be placed in the frame. If this is too high or too low, the reading portion of the lenses won’t be in the right spot. Headaches and neck strain can be the result.
- Verification. Once an order is filled, all of these measures just reviewed, as well as, the actual power and quality of the lenses is verified before the eyeglasses receive their final adjustment when you pick them up.
So, what about the online eyeglasses on the Internet? Well, they may be less expensive, but there’s a price to pay. When you order online eyeglasses, most of these measurements fall to you for accuracy. Only an optician or optometrist or ophthalmologist have the equipment and experience to collect all of the measurements necessary, and to verify that your prescription is filled correctly. Also, the online opticals will never be able to adjust your eyeglasses or service them. Ordering online eyeglasses is tempting, but it’s always better to leave this to the professionals.
