The Ultimate Eye Guide For Screen Eyes

Published on

#ContributedPost

Screens are an important part of all of our lives. The daily use of smartphones continues to grow among adolescents, with more than 90% spending more than two hours in front of the screens every day. New technologies allow for better communication, relaxation, and fun at the same time. High-tech companies have managed to transform the habits of college students and adults at work in depth.

Strategies to adopt 

Let's start with this misconception: No, you don't have to give up new technologies and screens to see well! However, it has been proven that looking at a screen for a long time can alter vision and also cause visual fatigue. If you are a teenager (or adult), the first piece of advice is to make sure that your visual acuity is good. Don't forget to regularly check your eyesight since a necessary correction may appear that had previously gone unnoticed. When in doubt, visit the ophthalmologist. Even if your vision seems perfect, you need to see your doctor every year. It's better to prevent than to cure. When in front of the screen, do you notice that your eyes feel dry or itchy? Here are some solutions to avoid these problems:


  1. The presence of reflections on your screens can make reading more difficult. You can adjust the contrasts in the parameters of your computer.
  2. In front of the computer or television, always place the screen perpendicular to the window and not right in front to avoid too strong of a light intensity.
  3. Do you use a smartphone or tablet? Consider changing the space between your eyes and the screen. Exercise a different distance or new approach every so often.
  4. Finally, remember to air the room you're in to avoid dry eyes.

Like every organ in your body, your eyes need frequent rest to stay at one hundred percent. So give them a break to relieve them!


Protect yourself from blue light

Every day that you use your smartphone, tablet, or PC, you're exposing your eyes to blue-violet light. The problem is that this light is partly responsible for the development of DMLA, a serious disease of the retina that occurs with age. Moving forward, you can take action by choosing to use lenses that are specifically designed to filter this harmful light such as Essilor® Eyezen™ (recommended from 20 years old). It's never too early to worry about your eyesight!

Blue light is the most dangerous region of visible light for the human visual system. Its wavelength is between 380 and 500 nanometers. It is emitted by natural sources such as the sun, but also by artificial sources such as LED bulbs or the screens of electronic devices (tablets, televisions, computers, smartphones, etc.). Exposure to blue light has increased a lot in recent years mainly due to the increase in the use of LED-type lights, leaving incandescent lights behind. On the other hand, the use of electronic screens both at work, home, and schools has also increased exponentially in recent years. Therefore, we must be aware that we are constantly exposed to this type of light in our daily lives. There is also evidence that blue light can interfere with people's circadian rhythms. This makes it more difficult to fall asleep due to the dependency on light and temperature. When the ambient light decreases and we expose ourselves to the wavelengths emitted by the screens, our biorhythms can be sped up rather than slowed to allow us to rest better.

External agents harmful to the eyes

There are also environmental factors that can also be harmful to eyesight. Examples include allergens such as pollen or mites, as well as pollution, color, and even excessive heat or cold. To avoid those elements inherent in the air, the use of sunglasses is ideal. Protecting your eyes from the sun is important, and not only in summer. While the main intention is to protect the skin, the eyes are more sensitive to the sun. This makes their protection against the sun's rays crucial. Sunglasses are the overall best solution, and you should wear them whenever the sun is out. Even during autumn and winter, the sun can still cause damage. Look for sunglasses that offer benefits for eye protection.

Healthy eyes


For good visual health, eat oily fish and boost your intake of vitamin A (carrots, spinach, tomatoes, or peaches). Vitamins C (citrus fruits) and E (oils, cereals and nuts), as well as lutein and zeaxanthin (spinach or chard) slow down ocular aging and prevent diseases such as macular degeneration or cataracts. The following tips will be largely beneficial for your eyes:

  • Eating habits play an important role in our visual health. A healthy diet with the presence of vitamins (A, C, E ...) and antioxidant elements has many benefits for eye health.
  • Eye hygiene is also important. You should not touch or rub your eyes with your hands, as you could expose them to infections.
  • It is essential that you protect your eyes from the sun with approved solar lenses, which you can find at your trusted optician.
  • We must avoid unnecessary efforts in our sight. Not wearing the correct optical correction forces our eye to make harmful extra efforts.
  • Little sleep causes the eye to recover poorly from the aggressions of the day. During the night, there is a regeneration of the epithelial cells that line the front of the eye.
  • It is critical to properly illuminate the object we are looking at (a book, a mobile, the TV, etc.) Avoid reflections and light falling directly on our eyes.
  • We must maintain an adequate distance from the objects we are looking at.

Wearing glasses


You may need glasses after prolonged computer or screen use. Glasses can protect your eyes and prevent them from having to work as hard. There are a range of different glasses available - you can choose here. Some people may choose to use contact lenses, but there are things to note if you make this decision. A prolonged use of contact lenses (more than 8 hours) can cause intolerances, allergies, or infections. Stop use immediately if you have redness, blurred vision, or pain. Also, avoid using them in the pool or in the sea as the microorganisms present in the water can adhere to them and cause serious infections.

If you want to keep your glasses in good condition for a long time, clean them every day with soap and water or a microfiber cloth. This removes grease and moisture without leaving marks on the glass. Also, take off the glasses with both hands to avoid damaging or stretching them and store them in a hard case to prevent them from getting cracked or damaged further.

If you still wear glasses or contacts but find that you are getting dry eyes, you should proceed with caution. Do not expose yourself to drafts, as they favor the evaporation of the tear. For example, do not point heaters or fans towards your face and refrain from driving with the windows open. Also, avoid wind in the field or beach, house dust, tobacco smoke, or solvents. Use room humidifiers at home.
