Eyesight is one of the main senses that a person relies on, but in the modern world it is more vulnerable than ever before. Every day around us are full of bright monitors, screens and other eye irritants especially if you are a student or your job is connected with computers and texts as editor/proofreader. It is eyesight that suffers from them in the first place. To keep it as long as possible, it is worth adhering to certain rules – to observe the so-called hygiene of eyesight.
Workplace Engineering of a Document Editor
To find a good document editor service is no longer a problem. Any document editing let alone proofreading especially if it is professional is time-consuming. Far from everyone is an academic editor or proofreader, which is why such online services are a real catch for any student who needs help. With such a company as essay-editor.net, you will improve your business English too because this is the company, which makes college students’ dreams come true. The less time you spend on working on your assignment on english, the healthier your eyesight is.
Most of us often have to sit at a computer monitor or read texts printed on paper. Ophthalmologists advise remembering a few important things when organizing the workspace where many people spend most of their time doing editing/proofreading or else.
- The light should be uniform and not flickering, and its sources should not affect the chemical composition and physical properties of the air.
- While reading, or academic writing, the light source should be behind the person’s shoulder. When writing for left-handers – on the right, for right-handers – on the left, so that there is no shadow from the hand.
- The printed text or text online should not be brought closer to the eyes than 30 centimeters. And when working with a monitor, this distance should double.
- It is better not to put a table lamp behind the monitor. If this cannot be avoided, it is better to direct its light towards the ceiling. The monitor itself is not recommended to be placed next to the window, and if there is no other place to provide one`s services, it would be good to hang blackout curtains or window shades.
- Subdued diffused light is suitable for working at a computer, but in no case is darkness – such conditions can greatly harm the eyes.
- Professional scientists from the USA have recognized the Verdana font (size 10-12) as the most optimal for eyesight.
- The screen is best positioned at an angle of 90 degrees. The top edge of the monitor should be slightly below eye level. It is important to wipe it regularly without damaging the special protective coating.
- The liquid crystal display must be set to a refresh rate of at least 85 Hz. Ideally, its illumination and the illumination of the workplace should match. If the document on the screen looks like a light source, the brightness should be reduced, and if it seems gray, increase. The contrast between the background of the text and the letters should be as high as possible.
- If your business is connected with working at a computer, it is important to take breaks after about 40-50 minutes. This time is for everyone individually – you need to listen to your feelings and avoid excessive eye strain.
Those who are fond of reading on the subway or bus should remember that ophthalmologists are categorically against this. Due to shaking, the distance to the text is constantly changing, and if for a person as a whole this is not noticeable, then it requires a lot of effort from the eyes. They are forced to reconfigure almost every second, which greatly wears out the eye muscles. Doctors are also against reading on the go and even lying down. And, as in working at a computer, sometimes you need to take breaks of 3-5 minutes while reading.
Even hairstyle can affect eyesight. Bangs hanging over the eyes, for example, can be very tiring for the eyes. Therefore, experts recommend choosing other styling options whenever possible, especially for children.
Rest is the best medicine
Timely rest for the eyes plays a huge role in maintaining good eyesight. Severe overwork can lead to pain due to increased intraocular pressure, inflammation, ophthalmic migraine or dry eye syndrome. Doctors emphasize that chronic eye fatigue increases myopia and hyperopia, and also leads to spasms and deterioration of visual acuity.
Doctors advise you to regularly ventilate the room, look away into the distance, and preferably out of the window, get enough sleep, eat foods that are good for your eyesight, do not forget about walking in the fresh air and pamper your eyes with massages and herbal compresses.
Here Are Some Tips on How to Help Tired Eyes:
- the easiest way is to close them and imagine something pleasant as soon as discomfort arises;
- “20-20-20 rule”: every 20 minutes you need to look at an object located at a distance of at least 20 feet (about 6 meters) and look at it for at least 20 seconds;
- if your eyes are working hard, you should learn to blink more often to give them enough moisture. If the loads are very large, you can use special drops that are used before starting work and during increased loads.
- those who spend a lot of time in front of the monitor should take 15-minute breaks every two hours. At this time, you can walk, jump, squat and do gymnastics for the eyes: move your eyes, rotate your eyes, look at your nose, blink intensively, and so on;
- palming, invented by the American ophthalmologist William Bates over 100 years ago, is considered a simple but effective exercise. In his opinion, in order to give the eyes a rest, it is necessary to close them tightly with rounded palms and sit like that for a while.
If something gets into the eye or you feel discomfort, do not rub it with a handkerchief or bare hands. To do this, it is better to use clean disposable handkerchiefs or special sterile sanitary napkins for the eyelids. If simple manipulations do not help, you should seek medical assistance.
Contact Lenses and Glasses
Speaking about hygiene of eyesight, it is impossible not to mention glasses and contact lenses. With the first, everything is more or less clear: the doctor always picks up glasses, and taking care of them is as easy as shelling pears – just store them in a case, periodically wipe them with special sprays and napkins, and wash heavy dirt with water.
For Those Who Use Contact Lenses, There Are Hygiene Rules:
- You can only clean contact lenses with special means, among which there are multi-purpose ones, but it is absolutely impossible to use water or saliva for such purposes – this can lead to unpleasant complications;
- You can sleep in contact lenses only if they are intended for this;
- Even with the best care, you should not forget to change the lenses for new ones at the end of their service life.
Increasingly, contact lenses are used to correct eyesight in children – doctors prescribe them from the age of seven. It is important that the child approaches hygiene issues with all responsibility: carefully store the lenses and properly care for them. Doctors say that children often follow instructions even more strictly than adults. This means they are less likely to experience complications.
It is impossible to take care of your eyesight in hot weather without sunglasses. If you choose them correctly, they will be a real salvation for sun-weary eyes. Ultraviolet light can severely damage the eye tissue, cornea, lens and retina. Glasses not only protect against this, but also give the picture greater contrast and protect the eyes from blinding light, which is necessary, for example, while driving a car.
- It is important to pay attention to the degree of protection. You can check it by special markings. There are different quality standards depending on the country of production of glasses. Europe marks quality products with CE symbols (Conformite Europeenne), the USA – 400UV or UV100%.
- The more UV the glasses can absorb, the darker the lenses. However, it is impossible to focus only on this sign. If the glasses are made of ordinary plastic, they will not protect against harmful effects. What’s more, it can make things worse: the darker the lens, the wider the pupils, allowing more UV light to enter.
- It is better for children to buy sunglasses with durable polycarbonate lenses. And for those who have problems with eyesight and wear glasses all the time, it is better to take lenses with a slight darkening for the summer.
- The shape of the glasses also affects the protective properties. If bright light enters the eye from above the frame or from the side, the effectiveness of protection will be greatly affected. Correct glasses should fit snugly on the nose, but so that the eyelashes do not rest on the glass.
The quality of the lenses can be checked with a simple test: place the glasses at a comfortable distance, cover one eye, and look through the center of the lens at an object with straight lines with the other. If you slowly move the glasses up and down and from right to left, there should be no distortion of the lines.
