View Full Version : Progressive or bifocal?

I'm coming back to flying after "some" years and need reading glasses. I am trying to figure out the best type of glasses to get for flying. I was told that progressive lenses were the way to go so I got some and am trying to get used to them, but not sure if I can. For those that use progressive lenses, did you adjust your focal point further out for the reading portion of the lens? Suggestions?

Progressive. However get WIDE CHANNEL. Normal progressives have a very narrow vertical channel to look through. It took about 3 days to get used to where to look with the eyes and some head tilting. Now it’s seamless. Wide channel is the key though. Otherwise you’ll be doing a lot of side to side head movements.

I like progressives because you have more than one power of magnification from which to choose. This helps with intermediate distances -just raise or lower your head a bit to find the magnification you need. Bi-focals or tri-focals are a bit easier on the eyes during a long day, but I have no real problem with my progressives in this regard.

Width of focal channel isn’t as important as segment height. I had them start the transition from a third of the way down from the top of the lens, which gave me basically divided my lens into thirds for distant/intermediate/near.

Good progressives aren’t cheap, and cheap progressives aren’t good. I went with the Varilux S4 Digital made by Essilor. Very good computer-designed lens, no swim effect, and edge-to-edge focus in the distant zone. Pricey but totally worth it. Have em in both clear and sunglass.

Agreed with the above, I used reading glasses only 'till two years ago, I noticed my mid vision was not as good as before, that's when I decided to get the progressive lenses, wide channel also, I took longer than the norm to get used to them but that's just me.

For flying have your opto make you a set of glasses with tint on them ( your prefer color ) and have him mount them on a rap around frame.

This is my opto guy ( Bruce ) if you like you can call him and explain him your needs, he Will work with you to get you the best fit, he has helped at least two of the Reno Racer pilots.

Best of luck.

Excellent idea of dividing the lens progression into three thirds, mid range should enhance doing it that way.

Me like :)

I have yet to fly with anyone that likes progressive's for flying..Bifocals with the cutoff at the top of the instrument panel works the best for most.

No perfect solution... it gets really interesting trying to crane your neck “up” further than normal to get focus on the overhead panel. That upper portion of the glasses is normally set for distance vision.

Hey, there are optics companies that will custom make trifocals specifically for the overhead of the AC you are flying.

I had two glasses made with the progressive-type lens. Hated them. Had them converted to tri/bi-focals.

I usually use a 1.25 reading glasses for reading and intermediate, and look above the glasses for far. That seems to work pretty well.

I just got new bifocals, with a minor far adjustment, and the rest is intermediate. On the aircraft I fly, nothing I am reading (yoke/ipad) is close up, so the intermediate part of the lens works both for reading and looking at the panel.

I use Varilux progressives—super easy to adjust to and use. Loved them from day one. Worked with reading charts, looking cross cockpit and using the HUD.

This is what I've been looking for. A friend of mine has trifocal glasses that have just what I want: distance prescription in the middle, computer/instrument panel middle distance in the bottom third, and the close/reading prescription on the *top* so you can focus on the overhead panel and switches. I will check out this website to see if I can have some of these made in both clear and sunglasses.
