Have you ever visited an eye doctor? Maybe at some part of your life, you might have undergone visual acuity testing. Nowadays, eyes problems are more than before. It is because of many reasons; for example, we use a smartphone that emits dangerous rays that can affect our normal vision. Apart from that, many other known factors may cause visual problems.

 

Moreover, with the advancing age, you can assume the visual problems are due to muscle strength issues. Overall, we need to measure visual acuity to diagnose vision problems. In this article, we will discuss the role of acuity charts.

 

Chapter 1: Vision Charts Basics

 

What is Vision Chart?

 

When visiting the eye doctor, you might have heard of vision 6/6 or 6/36. Can you decode these terminologies? Remember, these are nothing but indicators of visual acuity.

 

So, a vision chart, also called an eye chart, is a diagram upon which different words are printed. Those words may be numbers or, sometimes, alphabets. The most important thing to mention here is their sizes. The size of the digit or alphabet determines whether you are 6/6 or 6/60.

 

When it comes to the eye doctor, the doctor commands the patient to look at the eye chart and determine what is written on it. A normal vision person can point out the exact while the diseased patient will either be hyperopic or hypermetropic. That's how eye charts help the eye doctor diagnose the vision acuity problems in the patients.

 

What is the ultimate goal of using an Eye Chart?

 

The purpose of using the eye chart is nothing hidden. Every eye patient knows why the doctor asks him to look at the eye chart. However, let me list the reasons behind this fact.

 

• Eye doctors can quickly diagnose eye disease.  
• It ensures the accuracy of the treatment being prescribed to the patients. For example, if you recommend contact lenses, it is no longer a problem determining the accurate lens of contact lenses.  
• It assists in measuring visual acuity for better vision in the future.  

 

So, a visual acuity chart is much more beneficial for eye doctors.

 

Why do I need the Eye Chart?

 

A good question is here. What do you do? Are you an ophthalmologist or optometrist? If you are one of many doctors, it is essential to keep the health level of your patients optimal. So, how will you do that?

 

Obviously, by checking the many variations in one eye and the other eye-related to vision disease. Moreover, it will help you accurately diagnose one eye or both eye diseases. Many doctors around the world check the patient's vision through eye charts.

 

Chapter 2: What are the different types of Eye Charts?

 

Eye charts come in different varieties. Some will have the different sizes of digits written on them, while others will contain single letter e with different sizes. So, eye charts comprise the following types:

 

Snellen Eye Chart

 

Who doesn't know the Snellen eye chart? The first letter on the Snellen acuity chart is the big letter E. A dutch eye doctor Herman Snellen created this type of eye chart to help diagnose near vision and far vision diseases. When reading the capital letters on the Snellen chart, you can observe the same letter size in one row while decreasing size from top to bottom. The Snellen chart is a standardized eye chart to measure the visual acuity in hospitals and clinics.

 

 

 

Tumbling E Chart

 

The tumbling E Chart is a visual acuity chart with different sizes and shapes of the letter E. It is mainly designed for those children or people who can not read the alphabet. The eye doctors ask the patient to lift their hand and tell what the orientation of the letter E is on the Tumbling E chart. Sometimes the same size word is available in a row but in different directions.

 

Landolt C

 

Landolt C is a visual acuity testing tool that has different sizes of Letter C printed. Sometimes, we call these letters to be Landolt rings. The muted children or adults have to look at Landolt rings and speak what they see. Simples pictures are helpful for vision examinations in these cases.

 

 

 

ETDRs

 

ETDRs are not an eye chart but help in vision screening in the patient. We call it the Early Treatment diabetic retinopathy study. Nowadays, it is also a standard for vision testing to overcome vision problems.

 

Chapter 3: What should you look for in a digital vision chart?

 

Are you going to buy the digital eye chart for distance vision? Great! Never fall prey to the scammers. It is better to check the eye charts available worldwide to test the visual acuity and use them.

 

When finding a better eye chart, you must look at the following points that are helpful in pointing out eye diseases.

 

Automatic functioning

 

Basically, there are two types of eye charts available out there. One is in the form of static. That means you can't change the graph. Other is a digital eye chart. In digital eye charts, you can observe the slides and, surprisingly, change them.

 

Digital eye charts reduce the efforts and investments in buying multiple eye charts at a single time. So, when looking for ideal eye charts, it is better to determine the characteristics of the given eye charts and make sure it is automatic or digital.

 

Control System

 

In digital eye charts, you need to check the control system. Whether the tool is easy to operate and control or not. Some digital eye charts facilitate the users with numerous features, but one thing is missing in them. You know, what that is? It is a better control system available in them.

 

Usually, digital eye charts enable the users with automatic features. The remote control setup makes it easy to change the slides, point out specific parts during the vision, and implement other changes required for vision testing.

 

So, it is better to check out the control system of your ideal eye charts.

 

Types of eye Charts Available

 

Remember, there are more than four types of eye charts. When looking for an eye chart, you need to ensure whether it provides all the numbers or Alphabets with different sizes or not. If it does, it is simply fantastic.

 

A digital eye chart must function like slides changing, showing different charts with colors. So, check all these things when finding the best material.

 

Pricing

 

Who does want to invest again and again? Or even no one wants to buy something at a higher price. This thing compels eye doctors to focus on the pricing as well.

 

When looking at the price, compare different equipment at the same time. Check out their feasibility of working and land on the best one. The premium strategy is to find cost-effective eye charts.
