Many of us put of wearing Eyeglasses for a longer time than we should. We try to cope with using the squinting technique or holding books and phones at arm’s length to try and get a clearer view. It does reach the point though, when your arm is not long enough and the squint still leaves you with blurry vison and at this point, we give in to needing eyeglasses. Then comes the one hundred questions of what eyeglasses do we need? What strength do we need? What frame do we wear? What if we look and feel funny wearing a pair of eyeglasses? Well, none of this matters any longer when you find the perfect pair of eyeglasses and you have lost that blurry vision.
Eyeglasses are mostly used for vision correction, more commonly with reading glasses and glasses used for nearsightedness. There are various types of eyeglasses that are best suited to the different kinds of eyesight that is affected. A visit to our local optician can help us to know which eyeglasses will help us the most. There are different focal types including single vision, bifocal and trifocal.
Single Vision Eyeglasses – Single vision lenses are a type of glasses lens that correct vision for a single distance. That means that they work for people that are nearsighted or farsighted, but not for those who are both.
Bifocal Eyeglasses – This type of multifocal lenses has two prescriptions, one for distance at the top and one for near vision at the bottom. Bifocal eyeglasses have a visible dividing line or curve on the lens. There are four types of bifocal – D Segment, Executive, Round Segment and C Segment. Your optician will prescribe one of these shapes depending on your lifestyle and visual needs.
Trifocal Eyeglasses – Trifocal lenses correct three types of vision: close-up, intermediate, and distance. You may be more familiar with correction for distances far away and near, but you likely use your intermediate vision quite often. When you look at an object that’s a few feet away, like a computer screen, you’re using intermediate vision. Correcting all three types of vision may be necessary as you age. Trifocal glasses and some types of contacts can do this.
Those of us who wear single vision lenses will usually find the options to be fairly simple, and a store that has a laboratory on site can often have them made relatively quickly. Others with bifocal or multifocal prescriptions, however, have several options to choose from. The most inexpensive lens is a lined bifocal (or trifocal), which has strengths in it, they are a reading strength and distance strength. These strengths are separated by a line that can be seen pretty easily. There are many different frames to choose from to so we do not have to be overly concerned about how we may look with our new eyeglasses. There are a variety of shapes and sizes and we will be sure to find a pair that we love and feel are suited to us.
