Contacts vs. Glasses

I have been going back and forth in terms of whether to bring contacts or glasses on my trip. Fox wore two-week throwaway contacts. His hands were always dirty and every night he would remove the lenses and place them in their respectable holders along with a layer of dirt making each lens look like a bubble in a stagnant puddle. However, he did not get an eye infection until he got off the trail. Very interesting…

Morning Glory, wears glasses but did not wear them on the trail, which is probably why her vision got worse, she laments. She said on the trail she felt like she could see better and did not need glasses.

EYE on the other hand wear both contacts and glasses and have decided to list the pros and cons of each and weigh out the benefits.

Contacts

Pros

1. Ideal for exercise
2. Provide perfect peripheral vision
3. Stay suctioned to the eye
4. Comfortable
5. Don't obstruct view
6. No glare
7. Don't fog up
8. Don't collect rain droplets 

Cons

1. Require the added weight of contact solution and contact holders
2. Reduces the amount of O2 that can penetrate the eye
3. There is a risk that they will fall out when swimming
4. If you get something in your eye (e.g. a black fly of knat) you need to first remove them
5. At night you need to take them out; In the morning you need to put them in (Both of which require hands to first be washed)
6. If you drop them they are difficult to find
7. If you need to get up in the middle of the night to “heed nature’s calling” you must first wash your hands then put them in, only to again wash your hands and take them out before drifting back off to sleep.
8. You are touching your eyes at least twice a day which enhances the chance of infection
9. Require dexterity and possibly a mirror
10. Require lots of maintenance 
11. Expensive 

Glasses

Pros

1. You do not need to take anything other than a holder which your pot can double as
2. Allows O2 to fully penetrate the eye
3. Before swimming you simply take them off as opposed to taking contacts out
4. If you get something in your eye you can leave your glasses on
5. It is much easier to take your glasses off then take contacts out
6. If you drop them they are easy to find
7. Which makes going to the bathroom in the middle of the night much quicker and easier
8. You don’t have to touch your eye
9. Maintenance is much easier than that of contacts
10. Less expensive 

Cons

1. Need to be careful not to break them
2. Need to keep them in a case (Fox kept them in his 9000ml titanium pot)
3. Not ideal for exercise (slip)
4. Not as comfortable
5. Do not provide perfect peripheral vision
6. Fog up
7. Collect rain droplets 
8. Obstruct view
9. Produce glare 

I think it makes more sense to wear glasses on the trail, not only will it reduce the amount of weight in my pack, it will also keep my eyes enriched with oxygen and free of infection. Plus putting glasses on or taking them off is way easier than putting contacts in or taking them out because I do not have to have clean hands,  a flashlight, a mirror or dexterity.

Please offer some of your insight, thanks!
