Programmers Vision Problems and Computer Vision Syndrome

Programmers and other people who need to concentrate for a long time on computer screen suffer from two major maladies:

Less typical but still common for programmers is progressing of shortsightness even in advanced age (over 40) when for most people reverse processes take place due to loss of water in eye tissue due to aging.

Format of Eyeglasses prescriptions

Prescriptions have a certain format that is always followed. The first line of your prescription is always for the right eye, typically designated the “OD”. The second line is for the left eye, typically designated “OS”. The prescription for each eye is divided into Sphere, Cylinder, and Axis values.

It is common to have no values for any one of these, in which case you might see the letters “PL” or “plano”, or to have values for all of these. Sometimes the prescription may say “OU” which means “both eyes”.

Allergic conjunctivitis

Allergic conjunctivitis occurs when the clear layer of tissue lining the eyelids and covering the white of the eye (conjunctiva) become swollen or inflamed due to a reaction to pollen, dander, mold, or other allergy-causing substances.

 When your eyes are exposed to anything to which you are allergic, histamine is released and the blood vessels in the conjunctiva become swollen. Reddening of the eyes develops quickly, along with itching and tearing.

The allergens that cause symptoms vary from person to person 

Allergies tend to run in families, although they are not inherited in any obvious way. It is hard to know exactly how many people have allergies, because many different conditions are often lumped under the term allergy.

 Symptoms may be seasonal and can include:

 Your health care provider may look for the following:

Treatment of Allergic Conjunctivitis

The best treatment is to avoid what causes your allergy symptoms. It may be impossible to avoid all of your triggers. However, you can often take steps to reduce your exposure to triggers such as:

Lubricating eye drops can help decrease symptoms. You can relieve discomfort by applying cool compresses to the eyes. Over-the-counter oral antihistamines can provide more relief. However, they can sometimes make the eyes dry.

If home-care measures do not help, you may need treatment by a health care provider. This may include:

You may also use eye drops that prevent certain white blood cells, called mast cells, from releasing histamine. These drops are given along with antihistamines for more severe symptoms. They work best if you take them before coming into contact with the allergen.

Worked like a charm

5.0 out of 5 stars Worked like a charm Reviewed in the United States on November 3, 2020 Verified Purchase I've been skeptical of "online prescription" services since they first started popping up, but with the pandemic and generally not wanting to leave the house, I decided to roll the dice on this one. I was intrigued by the fact that it uses an actual motorized device and your phone to generate a prescription (eyeglass numbers, technically), and I figured it was worth a shot.

I've seen a lot of reviews that it's impossible to use, doesn't work, or generates an incorrect prescription. I'm not sure how much of that is defects in manufacture or operator error, but I can say that my unit worked perfectly. I can see people being confused by the process, and how you have to give it the 'thousand yard stare' to properly see the lines through the tiny slots, but I was able to line everything up and order a pair of glasses from a prominent online retailer the same day my VisionCheck unit arrived.

The prescription, or 'eyeglass numbers' was right on the money. I made a mistake in my choice of frames (didn't notice the ones I ordered were narrower than my old ones), but the difference between my old, outdated glasses and the new ones was night and day.

My only real complaints about the VisionCheck are that you need to manually pair it every time you use it (doesn't just automatically connect after the first successful pair), and that there is no way to cancel or undo a step when taking the test. At one point I fat fingered the "go to the next step" button on the VisionCheck instead of pushing the button to move the lines, and I had to manually go through each step of the test and then void the results instead of simply backing up a step and redoing it. A bit of a pain, so I recommend being extra careful about which buttons you push while taking a test.

Other than that, it worked great, and I'll be passing it on to my family members so they can use it too.

Very Interesting Product

5.0 out of 5 stars Very Interesting Product Reviewed in the United States on October 6, 2019 Color: A-white Size: 1 Count (Pack of 1) Verified Purchase I suffer from chronic dry eyes and puffy eyes. So I gave this product a shot.

I found it to be a bit heavy in a upright seated position, however, reclining or lying on a bed it is not heavy at all.

My first use was a bit surprising. The device does exactly what is described, massage, heat, vibrate, and music.

The eye massage applied a lot of pressure to my eyes and at first it was a bit uncomfortable after a couple of uses it was a non factor. The heat was nice and it feels good. The built in music leaves a bit to be desired and definitely is not my taste in music, HOWEVER... the Bluetooth feature allows you to connect to your phone and you can play whatever suits you. I like that feature a lot.

I use this device daily now and whether or not it relieves my dry and puffy eyes is not important to me any longer. It leaves my eyes feeling good and... I frequent fall asleep while using the device.

There are multiple built in settings lasting various lengths of time, and combinations of the features.

Over all, I think it is a good product and have recommended to a friend of mine because it makes my eyes feel good and I think it could make their eyes feel better. >

Arsalan Alizadeh 5.0 out of 5 stars Read my review before buying Reviewed in Canada on July 1, 2020 Color: A-white Size: 1 Count (Pack of 1) Verified Purchase First, these eye massagers are designed to massage the orbital rim not the eye itself.
Don't be surprised if they don't message your eyeballs.
Cons:
The nose piece might annoy the nose.
It might press too hard on temporal areas but not touches enough where it must touch.
No way you can know how much charge remaining.
Low volume for MP3.

Pros:
Ability to adjust temperature and pressure.
Ability to turn off pressure and just use as heat pad for those who have dry eye.

Update:
Overall: I ordered Osito and Breo as well as I wasn't happy with Renpho first. After seeing their performance being worse, I cancelled my return and decided to stick to Renpho. I think considering the price and options, Renpho is the best cost-effective choice on Amazon. >

Steven Paetkau 4.0 out of 5 stars Definitely worth it! Love the high heat option! Reviewed in Canada on April 18, 2020 Color: A-white Size: 1 Count (Pack of 1) Verified Purchase I bought the eye massager a few weeks ago and wanted to use it for a while before leaving a review. I've used the massager almost everyday, it has held up well and is very relaxing. At first, the pressure on your eyes is hard to get used to, and can cause some tension, but once you've used twice or so you're on to blissful relaxation! There is also some noise from the airbags/mechanisms inside the massager, but I'm not sure how they could get away from that. All in all I would really recommend this to a friend, and am looking forward to falling asleep with it on my face tonight!

[Mar 20, 2021] VisionCheck - Vision Test From Home - EyeQue

Mar 20, 2021 | www.eyeque.com

I got the first PVT in December 2017, and I liked it. I'm wearing glasses resulting from the numbers generated from that device right now.

The VisionCheck device is much faster than the PVT. It also is more repeatable, and I"m getting higher confidence values when I take the tests.

I was confused by the buttons, but I think I've figured them out. You have to tap them to get them to activate. Just pressing them doesn't seem to work.

As far as the PDCheck is concerned, I'm not as happy. I have yet to get the app to actually lock onto my pupils correctly. However, it does seem accurate if you adjust the crosses yourself with the app.

Super Fast & Accurate - But be mindful of the buttons! Overall Rating 100% I had the first PVT and the VisionCheck is much faster! But it's a completely different device with different buttons. I wanted to press down on them hard, but they're more like touch pads so I had to get used to how to tap them. The tutorial and practice helped, but it still takes some getting used to!

[Feb 15, 2013] What Is Your Favorite Monitor For Programming

Slashdot

Bigger tends to be better, but shoot for a 16:10 ratio screen. The 16:9 screens are nice but that extra shortness tends to be really annoying when your code really starts to grow.

Keith Mickunas
I too prefer a pair no matter the size. When developing in something like Visual Studio I have to run it in full screen. So the second monitor gets used for e-mail, web browser, references, etc.

I use 2 U2711 at home and it's wonderful. I also use a 17" alongside those. I use the smaller monitor for consoles or running something like uTorrent. Some people get caught up on the whole 16:10 vs. 16:9 issue, but at 2560x1440 there's plenty of vertical resolution there.

At work I use a pair of 22" 16:10 monitors. That's an ok setup and I've been using something similar at three jobs now. I'm considering picking up another pair of 27" monitors to use at work though. Either the 2713HM or perhaps some of the cheap Korean ones. Perfect color isn't a must for me when coding, so I don't need the 2711 or the better 2713 model.

AdamWill
I have 2xU2211H, both oriented portrait. I can see having one landscape if you need to work on video or something, but I don't.

I'd always go for the smallest display at a given resolution, to get the highest DPI: I much prefer 22" 1920x1080 to 24" 1920x1080. Still, I wish someone would make 200+ DPI desktop displays. Some day.

ChunderDownunder
I'm glad someone else gets it - many tasks are suited to length rather than width. Whenever a company supplied me with 'pivotable' monitors, I used to get strange looks in the office, even from supposed techies, about why one of my monitors was rotated pi/2.

Monitors that come with a pivotable base aren't the norm, so perhaps it's worth investing in one of those dual vesa mounts that clamp to one's desk. They're typically adjustable for a variety of angles.

[Oct 06, 2012] Computer vision syndrome

Wikipedia

Dry eye is a major symptom that is targeted in the therapy of CVS. The use of over-the-counter artificial-tear solutions can reduce the effects of dry eye in CVS.

Asthenopic symptoms in the eye are responsible for much of the morbidity in CVS. Proper rest to the eye and its muscles is recommended to relieve the associated eye strain. Various catch-phrases have been used to spread awareness about giving rest to the eyes while working on computers. A routinely recommended approach is to consciously blink the eyes every now and then (this helps replenish the tear film) and to look out the window to a distant object or to the sky-doing so provides rest to the ciliary muscles. One of the catch phrases is the "20-20-20 rule":[citation needed] every 20 mins, focus the eyes on an object 20 feet (6 meters) away for 20 seconds. This basically gives a convenient distance and timeframe for a person to follow the advice from the optometrist and ophthalmologist. Otherwise, the patient is advised to close his/her eyes (which has a similar effect) for 20 seconds, at least every half hour.

Decreased focusing capability is mitigated by wearing a small plus-powered (+1.00 to +1.50) over-the-counter pair of eyeglasses. Wearing these eyeglasses helps such patients regain their ability to focus on near objects. People who are engaged in other occupations-such as tailors engaged in embroidery-can experience similar symptoms and can be helped by these glasses.

A Pacific University research study of 36 participants found significant differences in irritation or burning of the eyes, tearing, or watery eyes, dry eyes, and tired eyes, that were each improved by filtering lenses versus placebo lenses.[3]
