It's that time in the decade..a few yrs ago I transitioned to Hoya progressive lenses with the help of a measuring chart from either AOPA or aviation consumer, I forgot not a surprise.

I'm measuring my distances within the plane I need to see but that is not my question, I'm considering Transitions which get darker in the sun. Does anyone have a recommendation for or against..

Obviously my concern is seeing the moving maps, nav equip etc.

any help would be greatly appreciated

I have progressive and I have photochromatic which darken in the sunlight - both of these work fine. The book for my Avidyne IFD540 says to avoid the use of polarized sunglasses. Most of the moving maps have a coating on the screen so this washes out the light I guess.

I've worn transitions for the last twelve years or so. Usually I'm flying with my polarized sunglasses, but night and most IMC I wear my normal (transition) glasses. My only glass is a 430W, and it's not a problem for either pair of glasses.

Before my cataracts surgery I had progressive with photochromic lenses. They work very well for near and far sight. If your plane or car has tinted windows they will not darken while inside but for sure when in the sun. After the cataract surgery I only use gradient sunglasses for daytime flying and driving. No need for lenses.

I had transitions for 1 year. They were OK in the plane but never got that dark.

The reason I didn't get them on the next pair of glasses was that the lenses would darken in any sunlight. So if I was in the hangar working on the plane and the sun was shining in in any direct angle to me they would darken and I couldn't see what I was working on. It drove me crazy!

I suggest getting a 2nd pair of clear lenses if you're going to get them.

I have transitions and have not had any problems.  They will not darken quite as much as if you were outside but that is not a bad thing.

 

Now for the progressives or I guess bifocals without the lines.  I have these as well and work well.  I have just my normal standard glasses nothing special for flying.  I can reference the GPS (KLN94)  my portable GPS and paper charts equally well.  I personally do not care for them when I'm dong computer work or a lot of reading but I have other glasses for those tasks.
