02. Laptops, Tablets and Smartphones. 5 Tips


Use adequate lighting, with ambient light and avoiding being in darkness on the screen. Choose a dimmed contrast and a smooth glow from your screen. Your visual effort will be reduced.


Adopt a comfortable and appropriate position in front of the screen with a correct angle, avoid neck and back pain.

Screen viewing distance

No closer than 40 cms is an adequate distance. Below this distance our eyes make a greater effort of focus and accommodation causing eye dryness, headaches and visual fatigue.

Rest every 20 min.

Take a short break every 20 min, look remotely by focusing on some object at a distance for a moment and go back to it again.

Eye testing

Any uncorrected visual defect can cause visual fatigue without knowing it. As simple as an eye exam and much better and without discomfort.

03. Your eyes in great shape

Protect yourself from the sun

Do you use sunscreen to protect yourself from the sun? In the same way you should be careful because the sun, and in particular UV rays, can cause serious injuries to your eyes. Choose sunglasses with the appropriate protection. Don’t gamble with your eyes !.

Are my glasses good quality?

Who has never suspected the quality of their sunglasses ?. The simplest and safest way, if they are not from a recognized brand is to go to the nearest Optician to check the protection of your lenses.

Dangerous imitations

It is easy to pay attention to “offers” almost irresistible in times of crisis. However, if those euros that you save reduce that are your visual health, do you think it’s worth it? Don´t put a price on the health of your eyes. What guarantees do you have to ask for:
-Pay attention to the “CE” brand as the minimum quality standard.
-The glasses must have the filter category number, that is, the absorption factor. It goes from 0 to 4, depending on the amount of absorption

Vegetables and fruit and Omega 3

As part of a healthy diet, in fruits and vegetables, especially of the green leaf variety, six nutrients have been identified: antioxidants, lutein and zeaxanthin, essential fatty acids, vitamins C and E and zinc mineral, which help protect the sight and promote eye health.

04. Good habits and your glasses

Use a microfiber cloth (not your shirt!)

A drop of hand soap and rinsing the lenses under warm water is enough. Dry them with a microfiber cloth, they are washable. Never with your clothes or packs of wet paper towels, you will scratch them over time. If it is dirty, replace it. Always keep your glasses in their case.

Be careful with lacquers and colognes!

Some products, such as lacquers or colognes, can be abrasive and harmful to glasses, as they can affect surface treatments. Be careful when using them.

Avoid heat sources.

Don´t leave your glasses near a source of intense heat, especially if your frame or glasses are made of plastic material.

In their case and facing up

Always leave the glasses facing up to avoid scratches on the glass. Whenever possible, keep your glasses in their case for protection.
