How to Choose Eyeglasses - Multi - Focal eyeglass lens advice

I’m Melissa with Woolenton Optometry for Expert Village here to tell you how to choose your eyeglasses. At every point in a person’s life they are going to need bifocal lenses, and there’s three major types that you can choose from. The first would be a line bifocal like this one here, where you have your distance at the top and then you actually have a line with a half circle and in that half circle is your reading. It’s great for somebody that just needs something simple and inexpensive and does not really care about the cosmetic appearance of a bifocal lens. The next step would be a trifocal lens like this here, where again you have your reading and you have your half circle at the bottom. Midway through this half circle is your intermediate distance. Great for computer work, or for anything at an arms length away and then at the bottom of your second line is where you’re reading is at. This is good for people who aren’t able to get adjusted to a progressive lens, because not everybody is. And then the last step is a progressive lens, it looks the same as a single vision lens, the difference being that it is done in the hourglass formation; at the top you have your distance, then you have your intermediate in the middle and your reading at the bottom. Again though since it’s done in the hourglass the outer portion of the lens and the inside portion of the lens there does have some distortion that lies in there, so you’re not able to cut your eyes from side to side to look at things you actually need to turn your head and look. With the newest technology some of the lenses have cut out a lot of that distortion but everyone still has a little bit so you still want to be careful of which ones you choose and obviously the better the lenses the less distortion there is going to be. So you might have to put a little bit more money into it but it’s usually worth it to do that. And if you aren’t able to get adjusted to the progressive check with your optician because most of the time they will go ahead and trade it out for lined trifocal or a lined bifocal at no charge since you are not able to adapt and those are your three types of bifocal lenses.
