In today’s busy world a lot of people are looking for an eye test online Either they are looking for eye test charts or some other online tool to help assess their vision or eye health.
We have given you information here about eye testing online and provided you with some charts for eye sight test charts for you to use at home.
One of the eye conditions we routinely see is macular degeneration. Also known as Age-related macular degeneration or ARMD. This is a condition that affects the central most part of the retina and vision gets blurred. Sometimes patients are not able to say if their vision is affected or not because vision is only marginally affected. It's obviously very important that this disease is caught as early as possible to enable most beneficial treatment. This test has multiple squares on it and sometimes patients refer to it as the squares eye test.
This is where the Amsler chart plays its role and you can download it below.
Here is how to use it.
If you are doing this test for the first time and notice wavy lines or black spots you need to be seen by a doctor as soon as possible to rule out a retinal disease.
If you are already a patient who has ARMD
If you have done this test before and have the previous recordings then this test serves as a follow-up. If your new recording is the same as the previous recording then nothing is needed. If however there is a change in your new recording then you need to see an eye doctor.
Many of our patients look to do a free online eye test to assess their vision. Even though online eye testing may not be the best there are a few options for you. These online eye tests have to be standardized because of the size of your screen, font, color contrast, and even brightness, all play a role in assessing your vision. When it comes to an online eye testing chart these things are difficult to standardize because of changes at the user end. Because this is not offered in all the available online tests there is no one best online vision test.
Many offer online eye testing but we doubt the authenticity of all of them. We have done our own research and found a few sites and give you some basic forms of online tests.
1) The first is from Essilor. The tests they have provided are basic for the reasons we have mentioned above.
2) The second is from Zeiss and this site does have some form of calibration to enable you to get an accurate result.
Here too we did some online research but no one has color vision testing with calibration. For online color vision testing, calibration of your own computer is the most important thing. we have found that the online chart for eye testing for color vision doesn’t have a system in place to calibrate your computer. We thus would recommend you to not try this at home/office but visit an ophthalmologist for the same.
ASTIGMATISM TEST ONLINE
Astigmatism is a condition where one has to wear glasses to see clearly. These glasses would mainly be for far but can be for far and near also. There are some eye tests online for this too. Here is one eye test online.
DIFFERENCE BETWEEN AN ONLINE EYESIGHT TEST AND A DOCTORS CLINIC?
When you visit a doctors clinic they would check for the following
In an online eye test, the following is checked
Ophthalmology is a very technology dependant specialty. Thus, ophthalmologists the world over are fairly technology savvy. There are also significant advances in technology being used in ophthalmology to diagnose certain eye diseases like diabetic retinopathy. As time goes by we are sure that usage of this technology will only increase.
That being said at the current time, the accuracy of these online eye testing sites is really doubtful. As mentioned in earlier there is a lot of standardization that goes into vision testing in a doctor's clinic. Very few online sites actually focus on the calibration of your computer screen to enable this standardization.
What these online eye tests currently do is give you a rough idea about your vision and if you should go see an ophthalmologist and that too to a small extent. They do not detect other serious eye conditions and you may be having.
