The progressive lens is not for everyone, however, anyone can learn to wear it. With proper education and instruction, adaption to a progressive lens is easy. The line that is normally on a bifocal is not just zapped off the front of the lens.

Generally your near distance is measured at about 16 to 18 inches or elbow distance. The intermediate distance is between you elbow and about 6 inches beyond your finger tips. The far vision is anything beyond the ends of your finger tips. When wearing a progressive for the first time you must tilt you chin toward your chest and look over the intermediate blend to see the floor since it is beyond your fingertips.

An increasing number of people who are in need of near vision help are turning to the progressive lenses for their vision needs. The need for near vision correction happens when the muscles and the interior lens of the eye begin to loose their elasticity much like a rubber band does as it ages. Progressives is more commonly known as the no line bifocal however it is more than a bifocal or even a trifocal.

This lens has a design much like an hourglass. The line that was present on a bifocal lens is blended into the outside or peripheral and the inside or the nasal part of the lens. The space that is created by this blend is the channel or corridor and that is where the intermediate or computer distance power is. This is also where the prescription power gradually changes from distance in the top to the near in the bottom.

A progressive lens is not designed to have clear vision throughout the entire lens. In learning to wear a progressive lens you must remember that like an hourglass the corridor is narrower in the middle than the top and bottom. To use the middle portion you need to use your nose like a pointer and turn your head slightly to look directly at your object to get the full advantage of the intermediate area. If you glance to either side you will run into the blended area and your vision will blur slightly. To adjust the power between the distance and the near you must move you head slowly up or down which changes the power according to how far away the object or reading material is from you.

In actuality, the progressive is a multifocal with many vision areas. The progressive lens gradually increases or decreases in power, much like the eye used to, as you move your eyes up or down the lens. So it maybe need time for you to get used to them.

It is a popular practice among people in those days to keep several pairs of s bifocal glasses in different colors, among which no line bifocal glasses stand out.

These glasses come in single vision type only. Prescription of a pair of reading glasses should be determined by an eye doctor, in the same way as prescription glasses for other refractive errors. Even if reading glasses are available over the counter, it is advisable to purchase customized ones from eye care practitioners.

However, a single pair of reading glasses is no longer capable enough if a person still has nearsightedness. Actually, such a combination is quite common in modern days. Many people suffer presbyopia after entering the 40s, before which nearsightedness has been existent for some years. Before the invention of bifocal glasses by Benjamin Franklin, this group of people had to use two separate pairs of prescription glasses, one for nearsightedness and the other for presbyopia. Fortunately, bifocal glasses in a single pair are designed to deal with these two problems at the same time.

Closely associated with natural aging, presbyopia is a health condition where the eye suffers a progressively diminished ability to focus on near objects, explained by Wikipedia. A noticeable symptom of presbyopia is that those old individuals have to hold books or newspapers at a distance farther than the normal. Only with such a distance can they get a clear view. The exact cause of presbyopia is still uncertain. Some professionals claim the research evidence supporting a loss of elasticity of the crystalline lens.

There are even more advanced options for presbyopia. Trifocal glasses add a third power for computer vision to bifocal glasses. In this case, a trifocal lens has three vision zones in separate. Progressive reading glasses have a smooth gradient of powers, rather than several separated lens powers.

Meanwhile, there is still studying evidence showing that changes in the lens’s curvature have also been discovered. In fact, all these symptoms or causes are to some extent an inevitable result of natural aging. This also explains why most presbyopic patients are over 40 years old. Without proper treatment, presbyopia can be quite bothersome in daily lives. The presbyopic may have much inconvenience while conducting even small chores on a daily basis. When the condition is advanced enough, some patients resort to a laser eye surgery. But the simplest way is to use corrective eyeglasses. Until now, there are several types of prescription glasses for presbyopia: reading glasses, bifocal glasses, trifocal glasses as well as progressive reading glasses.

No line bifocal glasses are the original version for presbyopia. With positive diopters only, reading glasses are capable enough of helping presbyopic individuals focus properly on near objects.
