I have them and love them . It is going on my second year with this pair. I have had contacts since I was 16 ...almost 62 now !! So I have a lot of experience. I tried the ones with long distance in one eye and close in the other..couldn't do it. I can't wear glasses at all so couldn't wear reading glasses with the contacts. I had "borrowed" as much as I could from my distance vision to help the close. My eye dr said last year that the bifocals had come a long way and that he would work with me and he thought we would be able to pull it off. Boy did he. I have all of my distance back again and my reading..I also have all the midrange for computer and piano that I could possibly want. The real kicker is that not only do I have the bifocal but I also have distance in one eye and close in the other ! He was able to combine the best of all and give me the best vision I have had in years. I see 20/10 now. I sure hope you will go to someone that will work with you as well as my dr did. I had to get 3 different left eye lenses as he made some subtle changes ...he sent them back and no charge to me at all. I am very very pleased. c

Joe's making a good point -- what focal length means has gotten a little confusing these days for the amateur photog with the advent of digital sensors in various sizes. Here's some more info: Focal length is the distance from the nodal point (center) of the lens to the film (sensor) when the lens is focused at infinity (the far horizon). Lenses come in three basic groups: short or wide angle, normal and long or telephoto. For any given camera the normal focal length lens is the diagonal of the film (sensor). 35mm film has a 46mm diagonal therefore the normal lens is 46mm (rounded up) 50mm. Focal length is related to angle of view which is likely what you're concerned about. Angle of view is a functon of focal length and the size of the film format. Simply put angle of view is how much the lens takes in. For what it's worth here's the math: Where V = angle of view, F = focal length, and N = length (width) of the negative: V = arctangent((N/2)/F)*2. Short lenses have a wide angle of view -- they take in more information. Long lenses have a narrow angle of view -- they take in considerably less information. Consider the two sunset photos below. The first was taken with a normal lens (45mm for 35mm film). The second was taken from the same camera location with a telephoto lens (135mm for 35mm film). Notice how the second sunset is just an enlargement of the central section of the first with most of the first photo cropped away. The photo below of the cross was taken with a wide angle lens (24mm for 35mm film). Notice how the shape of the cross appears distorted in the photo. The cross does not taper up yet in this photo the base appears larger than the top. This is because the camera is so very close to the cross. The human eye from the camera position would not be able to see the entire cross like this camera lens does. Standing there you would have to scan up and down the cross. Wide angle lenses (especially when used in close quarters) can show us aspects of the world our eyes do not show us and these photos can appear odd at times. Focal length is related to perspective. Perspective is a function of where you put the camera. Camera placement determines the apparent 3D relationship of objects in your photo. If you place yourself close to the objects in your photo the 3D space between them will appear emphasized and even exaggerated (common with wide angle lenses). If you place yourself far from the objects in your photo the 3D space between them will appear de-emphasized and even suppressed (common with telephoto lenses). This begs the question: Is there a correct focal length that will show viewers of my photos the scene the way it looked to me when I was there taking the picture? Yes there is; for a 35mm film camera that lens focal length would be 75/80mm. If that was all too esoteric and you're still with me here's a few tips for how to best use the different types of lenses. Short: expansive landscapes, tight places, buidlings and architecture, crowds and street photography. Normal: snapshots, family and friends. Long: isolate distance subject, wildlife, sports, fashion portraits. Joe

Often a fixture like that has little tabs you can't see that lock the glass dome in place. Put both hands in place on the glass and then try to rotate it firmly counterclockwise. It should turn, while the base stays in place. After you have turned it as far as it will go (maybe only an inch, maybe more), it should drop down...so keep a good grip. Let me know if that works for you. Good Luck.

I order contacts from Walgreens or through my eye doctor. Contact lens brands sometimes offer special promotions through the doctor. I go for the best deal of the two. There was no processing fee when I ordered from Walgreens or through my doctor. Walgreens online promotions vary from 20% - 25% off. After brand rebates that range from $30 - $50 off, you save money. I’ve never ordered from 800 contacts or other online places because I saw reviews complaining about looming expiration dates. With Walgreens or my doctor I get contacts with expiration dates 4 years into the future! That’s important to me.
