Bifocal Sunglasses

One upgrade to consider is a trifocal lens, which will allow you to more easily monitor your speed and see things that are at those in-between distances (not too far away, or less than arms' length).

The Fit

As far as bifocal sunglasses go, they're supposed to fit overall just like any other sunglasses. The difference comes in when it comes to the placement of the bifocal itself. The tops of the bifocals should sit about two or three millimeters below your bottom lash line. That way, when you look down in regular reading position, your eyes automatically find themselves looking through the special bifocal lenses.

You may ask why this is important since someone else will be filling your prescription and it's not up to you to decide. In a way, though, it is up to you to decide where to put the bifocal lenses. When you choose your frame, you'll need to make sure it feels comfortable. Make sure the nose guards are comfortable. Make sure the legs fit comfortable against the sides of your head and behind your ears. If adjustments to the fit need to be made later, that may disrupt the positioning of your bifocals.

The Downsides

There aren't really any. You may not be used to bifocals at all, so bifocal sunglasses may be a challenge to get used to. If you are used to bifocals, you shouldn't have any trouble--again, as long as they're positioned correctly.

One possible downside is the tinting. It's avoidable and reversible, but the eyeglass lab could initially make the tint too dark for your individual preferences toward the bottom; that could make it difficult to read. If this happens, you simply take them back to where you purchased them from and ask them to remove some of the tint. It doesn’t take long at all as long as they do the work in-office. You could be in and out in as little as 30 minutes with glasses in hand.

Other Options

Up until now, we've been discussing bifocal sunglasses with a visible line to mark the top of a bifocal. The other options are:

• Progressive sunglasses work the same way as the regular, old-fashioned bifocal sunglasses. The only differences are, there's no visible line and the change in lens power is gradual. Also, the measurement is different from the straight top bifocal. When the optician measures you, make sure you're seated comfortably and the frames fit well. Also, you'll want to ask for a gradient tint so that the bifocal lenses will be darker at the top and get lighter toward the bottom.

• Photochromic lenses simply get light indoors and dark outdoors. There is currently not a gradient tint option. However, they are available in progressive or traditional straight top bifocal lenses.

• Trifocal lenses are, as mentioned above, offer one more step between map reading and looking into the distance for driving.

• Reading sunglasses are great for those who don't need glasses to see objects far away. You simply slide them on when you need to read a map or read a book on the beach.
