Single Vision vs Progressive: What Are Their Differences

In this part, we will show you some differences between single vision and progressive lenses. They differ in several factors, so here we will compare them one by one.

Progressive lenses generally have their reading zones just in the lower half of the lenses, while single vision glasses have the reading power all over the lens. So if you are working on something above your head and you need to see some small details, the progressive lenses will not work. And you can not see through the reading zone in progressive you need to switch to single vision reading glasses.

Single vision glasses are cheap than progressive lenses. Compared to progressive glasses, single vision glasses hold way fewer distortions in the periphery. So, there is no need to customize the lens design to the max. In addition, single vision glasses are often available in the optical store while the progressive often needs to be produced for you. In other words, the delivery time of single vision lenses will be shorter for you.

You can use your progressive glasses optimally just in an upright posture. As soon as you lay down on your couch, this will lead to blurry vision. The reason is your changed position which forces you to look lower through the lenses on the screen. However, with single vision glasses, you can change to an upright position and it would not be a problem anymore. You can position yourself on your couch as comfortably as you want and you can still see clearly with your single vision distance glasses.

The frame of prescription glasses

At present, the more common materials for frames are non-metal and metal. Non-metals mainly include TR90, sheet material, etc., and metals include alloys, titanium, and so on. TR90 and sheet material are actually plastics, but they are firm and are not easy be deformed at room temperature. Also, they have good formability so that they can be made in many fashionable styles. The general alloy material has good firmness and flexibility, but the disadvantage is that it is easy to fade. The pure titanium frame is corrosion-resistant and very strong. It is about 40% lighter than the general alloy frame. It must be welded and electroplated in an oxygen-free state, which requires high equipment and technology. Relatively speaking, the price of TR90 and alloys will be lower, and pure titanium will be more expensive. You can choose according to your budget.

Why are blue light glasses yellow?

The material of the lens makes it turn yellow. If it's just blue and the lens is yellow, that's the material itself. Blue light glasses can weaken blue light entering human eyes. Blue light is mainly produced by mobile phones and computers in life. The blue light on the electronic screen is unchanged, so a film can only be designed on the lens to absorb blue light. This can effectively reduce blue light. The complementary color of blue light is yellow, so the yellowing of the anti-blue lens is normal. The material of an anti-blue light lens can effectively shield the blue light. If the blue light is removed from the white light we usually see, it will show yellow, which is a normal phenomenon.
