How to tie a winter scarf

October 22, 2009

how_to_tie_a_scarfThere are plenty of ways to tie a winter scarf; but after a friend showed me this method, I don’t think I’ll ever tie a scarf another way again. Most scarf tying methods I’ve found are bulky and uneven; but this method yields a knot that distributes the mass of the scarf evenly. So, it looks dandy underneath your winter coat. keep on reading »

Contact Lenses for Dry Eyes

August 03, 2008

Back in the good ol’ days, I could spend countless hours on my computer without much care – except for ergonomics, maybe. I noticed over the last few years that I was able to spend less and less time on my computer – my young supple eyes aren’t getting any younger. Apparently this is creatively referred to as Dry Eyes Syndrome. I figured there was no hope – that my days of spending long stretches on my computer were over; but a friend of mine told me to try Acuvue Oasys contact lenses. The Acuvue Oasys lenses – when used with Clear Care – have worked great for me. I’ll tell you more about it in this video.

Here’s a summary of the video:

Apparently, the problem is that most contact lenses are made with too much water. The contact lenses dry out during the day, and then wick moisture from your eyes. Which is a bad thing. One alternative is to switch to Gas Permeables, but they require an adaption period – though the vision they provide is supposedly superior to soft lenses.

Lenses like Acuvue Oasys are made with a Silicone Hydrogel, which contains less water than most lenses. Apparently this doesn’t fix dry eye discomfort for everyone, but it definitely works for me. Silicone Hydrogel is also used to make lenses that can be worn for 30 days at a time without removing them. That just sounds painful to me!

The Clear Care lens care system is a hydrogen peroxide system, which works great for me. For times that I’m traveling though, it’s not always convenient for me to use this system. In these cases, I’ve been advised to use straight saline solution because the chemicals in the multi-purpose solutions will get embedded into the lenses. I’ve got to wonder if I can just use hydrogen peroxide instead of the Clear Care system, though 😛 It would be much cheaper! (PS don’t try this – of if you do, it’s at your own risk. you may end up like this poor girl)

You can buy Acuvue Oasys lenses at 1-800-CONTACTS, and Clear Care at Amazon.
