The lightest full-size pair on this site and the one with the longest eye relief — which makes it the glasses-wearer's pair by a clear margin. Its one weak figure is the one that decides a window.

The Nikon PROSTAFF P7 8x42 is the pair to buy for someone who wears glasses: its published 20.2 mm eye relief is the longest of any full-size pair on this site, comfortably above the 16 mm point where views start to crop. It is also the lightest here at 20.8 oz. The trade is close focus — 9.8 ft, against 5 ft for the Vortex — which makes it the wrong pair for a feeder outside a window and the right one for almost everything else.
On method: we have not handled this pair. Every figure is Nikon's own published specification, read on the date in the sources, compared against the rivals' published figures. Nikon publishes an exit pupil and an apparent field of view that some rivals do not, and both are in the table below. If eye relief is a new term, the glasses guide explains why it decides this purchase for a lot of people.
How this review was built
The four figures from Nikon's table, plus the two extras Nikon publishes.
The eye-relief argument, because it is the reason to choose this pair and it is worth being precise about.
The close-focus caveat, because it is the reason not to, and it is a bigger gap than the others.
The comparison against the three rivals on identical figures.

Every figure is Nikon's own. Field of view is at 1,000 yards.
The eye-relief argument
Eye relief is the distance from the eyepiece at which the full field of view is visible. Glasses hold the eye further back than that distance on most binoculars, and the result is a cropped, tunnel-like image — which is the cause of almost every I cannot get on with binoculars complaint. The usual threshold is about 16 mm. The Nikon publishes 20.2 mm, which is not just over the line but far enough over it to suit thick frames, deep-set eyes and people who have given up on binoculars before.
The rivals here publish 17 to 17.5 mm. Those are fine for most glasses wearers. The Nikon is the pair for the ones for whom fine has not been enough, and it is the first pair on this site we would suggest to anyone who has tried binoculars over glasses and disliked it.

01
Nikon PROSTAFF P7 8x4220.2 mm of eye relief is the most generous figure here by a clear margin, and it is the number that decides whether a spectacle wearer keeps them.Under $250
Vortex Diamondback HD 8x42Nothing here is the best figure in its column, and nothing is the worst — which for a gift is exactly the right shape.Under $250
Celestron Nature DX 8x42The pair nearly every birding guide starts with, and the only one in this group that focuses down to 6.5 feet — which matters more than it sounds.Under $250
The default first pair, and the closest focus here
Athlon Optics Midas G2 UHD 8x428.1 degrees is a visibly bigger picture than anything else in this group, and ED glass is the reason edges stay clean at that width.Under $250
20.2 mm eye relief, which no other pair in this group approaches
Lightest here at 20.8 oz, which matters after an hour around the neck
Nikon's service network is the easiest of these brands to actually reach
What it does not
9.8 ft close focus is the worst in this group — a bird at the feeder ten feet away may not focus
Narrowest real field of view here at 7.2 degrees
Plainer finish than rivals at similar money, if that matters to the recipient
Who it is for
A glasses wearer, or anyone who has previously said binoculars give them a tunnel-vision black ring. That symptom is short eye relief, and this is the fix.
Skip this if
The recipient mostly watches a feeder from a kitchen window. At 9.8 ft minimum focus, a close feeder is exactly the shot these cannot take.
Pick 02
The best balance of the four numbers that matter
Vortex Diamondback HD 8x42
Nothing here is the best figure in its column, and nothing is the worst — which for a gift is exactly the right shape.
426 ft at 1,000 yards is 38 ft wider than the Nature DX, which makes finding a moving bird much easier
ED glass reduces the purple fringing you see on a bird against a bright sky
Magnesium chassis rather than polycarbonate
Lifetime warranty
What it does not
Heaviest here at 23.3 oz
Least familiar brand of the four, which can matter for a gift recipient looking for help later
The wide field makes the pair physically bulkier in the hand
Who it is for
Someone who already owns a cheap pair and has said they struggle to find the bird. Field of view is the fix for that complaint, and this has the most of it.
Skip this if
The recipient has neck or shoulder problems, or will carry these all day. Two and a half ounces sounds trivial and is not, after three hours.

Two clear wins — eye relief and weight — and two clear losses — field of view and close focus. The field-of-view loss is small: 377 against 388 or 393 ft is a few percent. The close-focus loss is not small: 9.8 ft against 5 ft is nearly double, and it is the difference between a feeder outside the window being usable and not.
The close-focus caveat, stated plainly
If the recipient watches a feeder from a window, do not buy this pair. A feeder six to eight feet from the glass sits inside its 9.8 ft minimum and will not come into focus. That is not a flaw for a walker, a hiker or anyone watching birds in a hedge or a tree, where nothing is that close; it is a disqualifying flaw for the kitchen-window watcher, who is a large share of the people this site is buying for. The from-home roundup is where this pair does not appear, and why.
The honest downsides
9.8 ft close focus. The longest of the four, and disqualifying for a window feeder.
Narrowest field of view here, though only by a few percent.
Warranty terms were not on the page we read. Check Nikon's current cover before gifting; the rivals here all publish theirs.
Nikon publishes fewer size figures than Vortex, so smaller-faced users cannot check the interpupillary range in advance.
FAQ
Questions people ask about this
Is the Nikon PROSTAFF P7 8x42 good for bird watching?
Yes, and especially for glasses wearers and walkers. It publishes 20.2 mm of eye relief, the longest of any full-size pair here, and 20.8 oz, the lightest. Its 9.8 ft close focus is the one figure to check: it is too long for a feeder outside a window.
Is the Nikon PROSTAFF P7 good with glasses?
It is the best pair on this site for glasses. 20.2 mm of eye relief is well above the roughly 16 mm threshold where the view crops, and comfortably more than the 17 to 17.5 mm the rivals publish.
What is the close focus of the Nikon PROSTAFF P7?
9.8 ft (3.0 m), per Nikon. That is the longest of the pairs reviewed here and rules it out for watching a feeder a few feet outside a window. For anything further away it is not a limitation.
Nikon PROSTAFF P7 or Vortex Diamondback HD?
Nikon for glasses (20.2 mm against 17 mm) and for weight (20.8 against 21.8 oz). Vortex for close focus (5 ft against 9.8) and for the unconditional warranty. Decide on whether the recipient wears glasses and where they watch from.
How much does the Nikon PROSTAFF P7 8x42 weigh?
20.8 oz (590 g), per Nikon — the lightest full-size 8x42 on this site, and the reason it leads the hiking roundup.
