What is eye screening?
There seems to be a growing interest in eye screening among the general public, but very few people know what it is. According to eye screening experts at https://www.drchelvinsng.com/eye-screening/
“Eye screening involves assessing the presence of some types of cataracts (cloudy lens), glaucoma (increased pressure inside your eye), or retinopathy (irregularly shaped tissue around the back of your eye).”
As for when you should go for an eye checkup, there are numerous opinions out there. The American Optometric Association says that it needs to be done every 5 years. The Mayo Clinic says that it shouldn’t be done before age 35 and at least once every 5 years after that. The American Academy of Ophthalmology recommends not getting an eye test done before 40 and again less than 5 years later, but then again in 5-8 years after that.

This is all just a bit of guesswork from experts who aren’t really experts at anything else. It’s best for a software company to take a more conservative approach, because even though we have experience and expertise within the industry, our product isn’t one which you can rely on for any sort of medical advice about your eyes, so we need to make sure we’re doing our part by educating others about the risks involved with going blind from their use if they do go wrong.
Going blind isn’t something which anyone should ever have to worry about — especially if they are using our product as intended — but in reality it is something which can happen thanks to many different factors connected with how each individual user interacts with our app. There are many ways this could happen:
- The user might fall victim to a virus or other malware while logged into their own computer via our proxy server; this could mean that their computer has been hacked by malicious software and they may have no way of speaking up until they go offline and re-boot their computer; unfortunately this could also mean that they will lose access entirely;
- The user might log out of the app through an error message on some other app (or another proxy server); this could lead to them losing access altogether; or it could simply mean that their internet connection has been interrupted for whatever reason;
- An unrelated issue like a power cut may restrict access from outside sources completely; if so, even if someone has managed to interrupt the internet connection from outside sources during their last session with our
2. What are the benefits of eye screening?
There are currently two types of vision screenings available: eye examinations and optical tests.
Eye examinations use instruments that measure different things about the retina. They are useful for many things, but most optometrists will have you do them only if you experience some kind of problem with your vision like headaches, blurred vision or photophobia (the sensation of being squinty).
Optical tests, on the other hand, make use of spectacles that detect lines and colors on the retina. This is useful when dealing with medical problems like cataracts or retinal disorders.
In most cases, optometrists will recommend a pair of spectacles to cover all your eyes. The downside is that they can be cumbersome; if you want to wear them around the house or out at night, then they’ll be a hindrance to your normal activities. So what happens when someone has “optical problems?” What should you do about it?
There are several ways an “optical problem” can manifest itself:
- Dimming – It happens when your eyes are too wet from tears or sweat, causing the lens to dry out and become less clear (a condition known as glaucoma). The best way to prevent this is to stop looking at bright lights around 2-3 hours before bedtime (and make sure you keep drinking water after this time).
- Cataracts – Cataracts in the lenses of your eyes cause objects inside them to be blurry; every time you look at something else bright, it causes a tiny bit of damage which builds up over time until it becomes a problem (think of a thick layer of mucus covering one side of your eyes).
- Retina disease – It is a common vision loss symptoms caused by degeneration in the retina in front of the eye. Symptoms include blurring or loss of sharpness in images seen from both sides (perifoveal) and problems seeing fine detail due to distortion (perifoveal scotoma), as well as problems seeing colors near objects (perifoveal color blindness). The best treatment for cataractous retinopathy is surgery and glasses with lenses designed for people with this type of vision loss.
- Glaucoma – Glaucoma occurs when fluid builds up behind the retina; with repeated exposure over time it leads to irreversible tissue damage so that there can be no recovery afterwards — even if treated early enough.
- Macular degeneration
3. When should you go for an eye checkup?
Writing an article about eye screening can be a daunting task — we all know that we need to eat and drink pretty much constantly, but you also have to take care of your eyes. Your eyes are in charge of your brain, and the important thing is that your brain is in charge of your eyes. You need to take care of your eyes and they will do the rest.
So what is eye screening? Here’s a quick summary:
– Screening means looking at things you want to look at (the screen) rather than things which you don’t want to look at (the monitor).
– Eye screening is a regular checkup when you need it, not a daily ritual. We all need our eyes checked several times each year so we don’t get blind or develop cataracts, but there are many reasons why it may not be possible for you to go for an eye checkup on a regular basis:
– You might be too busy or tired or anxious (so having the time gives up some value). – You could be going on vacation or traveling somewhere and it wouldn’t make sense (it would put too much pressure on you) – There might be an emergency, like driving over an icy road and the sun goes down while driving (not good) – The issue might be physical disease or injury (like vision loss) – You might not have access to an eye doctor – The issue might just not be worth spending the money on (a specific type of cataract is hard enough to treat without testing again every year)
Eyes are extremely valuable; so there should always be some kind of screening for them. But why must we go for this regular checkup? Why can’t it just wait until something bad happens? Let’s say you have a very serious problem with vision loss — maybe something like corneal damage from diabetes, macular degeneration from glaucoma, retinal detachment from diabetes etc. — then this would justify going for an eye test twice per year instead of once. And if the problem has already started affecting something else like hearing or speech perception then this would justify going through a more comprehensive exam like hearing tests or speech therapy as well. The point here isn’t whether these tests are worth doing sometimes vs other times but how they work together: if one factor has gone untreated then the other factors suffer as well. That is why we only go
4. What are the different types of eye checkups?
In the past, eyeglasses were worn to help people see better. Of course, this is a much more complicated issue than it used to be. Today, we have developed a lot of different technologies for trying to help people see better.
The first step to using these technologies is finding out what you need to do, and when you should do them. Next is figuring out what you don’t need to do anymore and when you should stop doing it all together (e.g., we don’t need glasses for reading text). Of course, we also have medical reasons why we should not wear glasses at all times and so on.
I heard an interesting story recently about a young woman who was diagnosed with an eye disease (a rare case of glaucoma) in her early 20s by a doctor who was not familiar with modern ophthalmology (or why glaucoma could happen). The doctor had been told that she would likely become blind anyway; she didn’t know that this was a possibility even if they did find out she had glaucoma at some point in her life.
In the face of modern ophthalmology, this doctor should have realized that there was no way he could actually treat his patient with anything but glasses — so he prescribed them for her — which may sound weird but actually isn’t: most doctors today know that glasses are the only thing that will help patients like this one without putting them at risk for serious side effects from medications or surgery. But there are still many cases where doctors simply don’t have the knowledge or resources to do any other kind of treatment; therefore, they can’t get rid of the symptom either through surgery or medication — so instead use their “hands-off approach” and just watch patients suffer in silence as they wait for their condition to get worse before they can pay any attention to stopping it or treating it.
I think this is particularly important today because many people are going blind because they cannot afford eyeglasses! With current technology available, there is no reason why someone like me couldn’t go blind even if I never needed eyeglasses in my life (if I really wanted), but I depend on people around me who rely on me for things like reading text. If I go blind soon enough without my sight being improved by something else (i.e., glasses), then I will not be able to read
5. What are the common eye diseases?
Here is a list of the most common eye diseases. I’ve written this article several years ago and it was the first time I came across this information, so my apologies if any of the links are outdated or wrong, but it should give you a good idea of what to look for.
The following list is by no means complete ; just a snapshot of what to look for in your own eyes. If you have any questions then please feel free to contact me at [email protected].
Conjunctivitis is an infection of the eye's surface. It can be caused by bacteria, fungus, viruses or allergies. Sometimes it may be accompanied by other inflammations, such as lid swelling and corneal ulceration. Symptoms can be quite different from one person to another and vary from mild to severe (sometimes even resulting in blindness). Any inflammation of the conjunctiva causes redness, tearing and itching. Conjunctivitis may also cause eye pain or pressure (elevated intraocular pressure), blurred vision or photophobia (painful light sensitivity).
Herpes simplex virus infections: acyclovir valacyclovir valacyclovir acyclovir acyclovir Various antiviral medications are available but some are contraindicated due to side effects . These include antifungals such as fluconazole (which should not be used if you have diabetes , heart disease , kidney failure or liver disease) or ketoconazole , which has been associated with cardiac arrests . Liver transplant rejection also increases your risk of having an immune-mediated reaction that could cause serious damage to the liver after receiving a transplant.
6. How can you prevent eye diseases?
I went to an eye doctor once. He was very good, and very thorough. All the same time, he was not my doctor. I went to see a different doctor the next day, who was also very good — he was much more thorough than the first one had been. Anytime I’ve taken a preventative eye test in the past few years, however, I’ve come back with a prescription for my own screening test.
This is an obvious example of a high-quality screening test — but what exactly is it? And why are we doing it?
Eye screening (or ophthalmology) is a convenient yet completely useless diagnostic tool that is widely used by doctors to choose between different treatment options (e.g., surgery vs. medication) and detect certain diseases early on. It’s called “screening” because you don’t need to prove that you have any particular disease when you take it; you just need to be healthy enough for your eye doctor to want to do something about it. In fact, most of these tests are non-specific: they succeed only in detecting some (probably minor) risk for an otherwise healthy person — which usually turns out not be true for at least 95% of the population at any given time. So how can we avoid wasting our money and time on these tests when there isn’t even any evidence that they might be useful?
The eye screening industry is based on five assumptions: 1) There is something inherently bad about your eyes 2) Someone somewhere has said so 3) Your eyes are getting worse 4) You should do something about them 5) You will get better if you do something about them
The first assumption is clearly false: There isn’t anything intrinsically bad about our eyes; anyone who has spent time around us knows this much already. Many people assume that everyone with poor vision must have sight loss of some kind; this isn’t true either; there are people who have perfectly good eyes but whose vision isn’t good enough for them to use them normally (a condition known as amblyopia). A simple exam will usually show that your vision isn't actually bad at all, but rather seems fine despite this fact because all that damage has been done in early development anyway without your conscious awareness. For example, take a look at Figure 1 below (it shows two photos from two different people with slightly different levels of astigmatism.
