Do I need trifocals instead of bifocals?

Trifocals vs. Bifocals

Trifocals are bi focal reading glasses with a third lens section. You need trifocal rather than bifocal glasses if you have trouble seeing your computer screen, book or needlepoint (hey, people still do it) within an arm's length.

Bifocal eye glasses and trifocal eyeglasses simply correct more than one vision problem simultaneously, e.g. macular degeneration, presbyopia, myopia, hyperopia. Bifocals primarily correct presbyopia. Trifocals just add eyesight insurance for people whose vision doesn't improve with bifocal reading glasses. If you think you need trifocals instead of bifocals, consult your optometrist.

   
How do I avoid having to crane my neck to adjust my sight with bifocals?

Avoid Rubbernecking

You've stuck your neck out so many times your friends say you look like a giraffe wearing bi focal reading glasses.

One way to eliminate the bifocals rubbernecking problem starts with the computer. Place the monitor so that the center of the screen us at about 17.5 degrees below eye level. Try to align your eyes with the top of the viewing area of the screen. Be sure to do this wearing your bifocal reading glasses.

Consider getting a stand or lapdesk for reading material rather than holding the print down so your neck and the curves of light constantly have to adjust. Read with bifocal glasses with printed matter at eye level.

You have enough to concentrate on during night driving without worrying about your bifocal eye glasses. The plus here is that moving your head during driving, provided you keep your eyes on the road, is actually a requirement. If you have difficulty seeing instruments or the road within arm's length, consider trading your bifocals for trifocals.

What exactly do bifocals do and who needs them?

What Bifocals Do For You

If you have presbyopia, in which the eye lens loses flexibility and can't change focus to see near objects, you most likely need bi focal reading glasses. If you have presbyopia and are over forty, you most definitely need bifocals. These are the most common reasons for needing bifocal glasses. More than 90 percent of people over the age of forty squint at a newspaper or the menu.

The high-tech lenses of bifocal reading glasses are split into two sections:

* Upper for distance vision
* Lower for near vision

Although people over forty overwhelmingly populate the “I wear bifocals” club, children ages 7 to 12 may need bifocal eye glasses. Children can develop strabismus, a vision problem in which the eyes do not look at the same point at the same time, also known as being cross-eyed, or ambylopia, or “lazy eye.” Some children with strabismus or ambylopia may need to wear bi focal reading glasses.

   
What are “E-Bifocals” and are they available on the market?

“E-Bifocals”

The Egg Factory is developing a proprietary technology to create E-bifocal reading glasses. These electro-active bi focal reading glasses can refocus automatically using chemistry and an electrical current on whatever you are looking at.

Wearers of traditional bifocal glasses have to crane their necks and turn their heads to focus thanks to the different curves of light from the two separate lenses.

“E” bifocals can automatically calculate the distance of where you are looking and convert that into a new curve using software, a microchip and the electrical current boomeranging off the field of vision back to the lens.

For now, you'll have to stick to your regular bifocal eye glasses. So far, “E-Bifocals” are only in the patent stage.

   
Can I avoid wearing bifocals that obviously look like bifocals?

Progressive Lenses

Bifocals don't have to look like bifocals. The progressive lens is a special kind of lens for bi focal reading glasses. There are no lines or half-moon “cutouts” in progressive lenses. Progressive lenses for bifocal reading glasses incorporate all corrections from distance to close-up.

Alternatively, the EZ-2-Vue Lens is a round segment for bifocal glasses blended into the distance part of the lens.

Progressive lenses look great and incorporate intermediate vision, e.g. the field of vision around a computer, better than segmented, lined bifocal eye glasses.
