What Are Single Vision Lenses?


Single vision lenses are surfaces of lenses with the same power along the entire lens. There's some amount of vision correction along the lens – either for nearsightedness, farsightedness, or astigmatism. Yes, you heard it right. You cannot treat your nearsightedness/farsightedness with a single piece of single-vision lenses. Uniform prescription through the entire surface corrects for one field of vision. Single vision lenses treat specific vision - that is myopia (nearsightedness), presbyopia (farsightedness), or astigmatism with constant correctness. 

What Are Digital Progressive Lenses?

 

Unlike single vision lenses, digital progressive lenses have varying power along their entire lens. The smooth transitioning in between the lens has 3 regions for vision. The top region assists in viewing the far object clearly without blurring out the field for your nearsightedness. Whereas the bottom region of this lens helps you to see the words. More sharply on a book while you're reading. The intermediate lens surface between the top and bottom helps astigmatism. These multifocal lenses correct your nearsightedness, farsightedness, as well as everything in between. 

Advantages and Disadvantages of Single Vision Lenses:


Advantages Of Single Vision Lenses:


Let's get through the advantages of single-vision lenses:


1. Simplicity:


Simple things are the easiest to adapt. Similar is the case with single-vision lenses. Their inability to focus on multiple visions makes them less complicated. These are straightforward and singlehandedly handle your either nearsightedness, farsightedness, or astigmatism!


2. Cost:


Who doesn't go for affordability? If you have vision impairment in a single direction, then single-vision lenses are the best option. They are cost-effective because there's no transitioning of multi-focal surfaces.

3. Clear Vision:


The phenomenon of a single-vision lens is the simplest. These are optimized for nearsightedness, farsightedness, and astigmatism. You don't have to tilt your head upwards or downwards to ensure vision correctness. 

4. Easy Use: 


People tend to buy single-vision lenses. Now, forget the different vision zones and enjoy the single frame for your eyesight correction!


Disadvantages Of Single Vision Lenses:


The following are the disadvantages of single-vision lenses:

1. Limited Range:


The biggest drawback of buying a single-vision lens for your frame is its limited range. It either deals with nearsightedness, farsightedness, or astigmatism. People above 40, with presbyopia and myopia end up buying multiple frames. With single vision lenses which costs them far more than digital progressive lenses.

2. Presbyopia Challenges:


A single-vision lens can't kill two birds with a single stone. These lenses do not correct seeing nearby objects. So older adults with presbyopia end up worsening their already damaged eyes. 

3. Appearance:


In the case of bifocals or trifocals, people get lenses with visible lines. These lines divide the portion of the lens. This seems off-aesthetic and tougher to adapt. 


4. Adaptation for Multitasking:


You could be driving and still find the need to look at the map. The task changed. You need two pairs of lenses with single-vision lenses. One navigates the way distantly while the other - at a map looking closely. This often gets exhausting without digital progressive lenses. You end up losing your focus with this less convenience.


Advantages and Disadvantages of Progressive Lenses 



Advantages Of Progressive Vision Lenses:


Let's dig deep into the advantages of digital progressive lenses:

1. Smooth Transition:


The natural and seamless appearance of prescription progression from distant to intermediate to near lies in digital progressive lenses. There are no harsh lines on the surface of your lens reducing the quality of your vision.


2. Multifocal Convenience:


Unlike single-vision lenses providing a single-vision zone correctness, progressive lens provides 3 zones of vision. There are no telltale lines like bifocal lenses differentiating the near and far zones. Enjoy several prescriptions in a single pair of glasses.



3. Aesthetic Appeal:


As mentioned above, there are no lines on digital progressive lenses distorting the vision or visual appeal of your frame. The lens is modern and aesthetically pleasing as compared to single-vision lenses with the same thick conventional surface.


4. Versatility:


It supports multitasking. With a pair of digital progressive lenses, you don't have to worry about where is your frame. Either for long-sightedness or short-sightedness. You can multitask. Read a book as well as ask your roommate to leave (face recognition) without switching the glasses!



Disadvantages Of Progressive Vision Lenses:


Following are the disadvantages of progressive vision lenses:

1. Adaptation Period:


While tilting your head and finding the right vision area of the lens for a specific distance. This adaptation period becomes back-breaking. It takes a good amount of time for a person to adapt to progressive vision lenses.


2. Cost:


Despite all the goodness. The cost of progressive vision lenses is slightly high. The technology involved in the seamless transition portion and customization level according to the wearer's comfort requires extra money. The difference between single vision lenses and progressive is higher cost too.


3. Peripheral Distortion:



While digital progressive lenses correct the vision of nearsightedness and farsightedness all along. The peripheral vision suffers. It gets exhausting to focus on all three dimensions together with this highly focused pair of lenses!


4. Frame Limitations:


You cannot choose every frame. Cause there is a chance that the small frame might not be effective. The small frame limits the portion of the lens and hence the vision impairment.

Difference between single vision and progressive 

There are two types of eye prescription. One includes single-vision lenses and the other one is digital progressive lenses. Single vision lenses account for correcting the single vision at a distance. Identical correction lies on the entire surface of single-vision lenses. Whereas, the progressive lens enables the vision correctness at different distances. Progressive vision lenses reduce the work. In a single frame, you get two lenses. 



Let's find out the in-depth difference between the design and functionality of single vision and progressive:


1. Correction Range

Single Vision Lenses:


Vision correction for either near, far, or astigmatism.


Progressive Vision Lenses:


Multifocal lens transitioning from top (distance vision) to bottom (near vision) through an intermediate zone in between.

2. Transition Zone

Single Vision Lenses:


A single prescription lens with no transition.


Progressive Vision Lenses:


Gradual transition seamlessly shifts the focus from distance to close.

3. Use Cases

Single Vision Lenses:


Suitable for children/adults with conditions like myopia, hyperopia, and astigmatism.


Digital Progressive Lenses:


Suitable for older adults usually above 40 with presbyopia. 

4. Appearance

Single Vision Lenses:


Uniform appearance and no harsh lines differentiate the portions of different prescriptions.


Progressive Vision Lenses:


Contemporary and aesthetically appealing look with no visible lines on the surface of the lens.

5. Adaptation

Single Vision Lenses:

Since there's only one prescription, the adaptation period is small with easy and simple use.

Progressive Vision Lenses:


The adaptation period is lengthy. It takes time to adjust the farsightedness, nearsightedness, and astigmatism all at once.


Enough swapping the frames. Whether you're driving or reading a book. Put on your frames with digital progressive lenses and help your daily life!
