Our eyes are on the front of our head, giving us excellent binocular vision but poor peripheral vision. “Their lateral fovea is used more for distance vision.” Eagle eyes are on the sides of their heads for a reason “Their central fovea is for close inspection,” Hodos explains. You might compare an eagle’s eye to a modern computer screen, with densely studded pixels giving extraordinary clarity and sharpness to every image.

Not only do eagles have two foveae per eye, each is packed with a million cones per millimeter. In a human, he explains, each fovea has 200,000 cones per millimeter. That depth allows eagles’ eyes to act much like a telephoto lens to capture images. The fovea in an eagle is like a convex, deep pit, according to Hodos, and in humans, it’s like a shallow bowl. In the center of the retina is a special area called the fovea where the cones are incredibly densely packed. The eagle’s vision “is so far superior to ours that we can only try to imagine what their world must look like,” says William Hodos, an expert in bird vision and a distinguished professor emeritus at the University of Maryland.īoth human and eagle eyes are built like a camera with a lens, containing light- and color-detecting cells on the retina called cones. So how does an eagle do it? How are its eyes like our own, and how are they different? Will technology and science ever help us catch up to the eagle and bring us our own version of raptor vision? Maybe so! How good is eagle vision? No wonder we use the term “eagle eyes” to describe superb vision. That means that what looks sharp and clear to us at 5 feet is just as clear to an eagle from 20 feet away. If you had an eagle’s ultraviolet light perception, you could track a tiny vole from the sky by the UV rays reflected from its urine.Īnd while most humans have 20/20 vision, eagles are blessed with an astounding 20/5 vision. If you were an eagle, you could see a rabbit running from three miles away.

My thanks to Dorrett and Sapna for their excellent customer service.Of all the eyes nature has ever produced, those of the eagle - with its large, hooked beak, pale yellow iris and powerful talons - may be the most extraordinary.Įmbedded on either side of its face, an eagle’s eyes give it nearly panoramic vision. Dorret worked with the head of the lab where the glasses are made and called me to follow up to ensure we made the best choice possible.With a colour change on the front, I received my new second sun glasses with exactly the view from within I was expecting (matching my original set) and I couldn't be happier.With so many choices within a 30 minute drive, I am thankful to have found such a highly rated location and the many 5 star reviews are well deserved.

Visiting Dorret and Sapna again we discussed all options and with the promo pricing they had on, for only few dollars more I picked up a second reading pair of glasses (as a backup set) versus buying just the sun glasses.When the glasses came in - the sun glasses had a small issue - the combination of the tint, colour and polarization made the view through them much brighter than I hoped.We discussed the options, figured out why it was happening and sent the frame back. They helped me choose out a pair of reading glasses and sun glasses, going through all the options and why I should choose them.You also get the warm feeling that if you ever need to stop in - as I do time to time - for a quick adjustment and screw tightening - they are happy to see you.I decided 2 months ago to pick up a second pair of sun glasses for sport activities.

This is actually 2 reviews in 1.Around 5 months ago I required wearing glasses once again (many years glasses free from laser eye surgery) and my thanks to all the previous reviewers - choosing this location near my home was an easy choice.Sapna and Dorret are awesome. Thank you Dorret for great service and i will be recommending my family and friends to come to your store. Well they came to her store she called me, and with in 15 minute she had the old lenses which were prescription poped out and put in the new frames. Well they were ans she asked them to send it to her store and she told me they should be here tomorrow July 20th. She looked the number up and called another store which was at Mavis and Britania which said they had one pair left, to make sure they were the ones she ask that store if they could send a picture of the glasses to make sure they were the ones. She went through her box of Bolles which they were there. They were Bolles which i believe had been discontinued. Just broke my sunglasses which i had since 2018, but she knew exactly which ones they were by looking at them.
