We spend a large part of our day in front of a screen: whether for work with a computer, for leisure with a smartphone, or in the evening in front of the TV. This constant digital exposure has led to an exponential increase in an annoying and widespread disorder: dry eye syndrome.
If at the end of the day you feel a gritty sensation in your eyes, burning, or redness, you might be suffering from what is known as Digital Eye Strain.
In this article, we will look at why this discomfort occurs and how an innovative and practical remedy can make a difference for your eye health.
Why does computer use cause dry eyes?
Our eyes remain hydrated thanks to the continuous renewal of the tear film, a liquid layer that is distributed over the ocular surface every time we blink. Under normal conditions, we blink about 15-20 times per minute.
However, when we stare at a screen, something involuntary happens: our attention becomes focused, and the blinking frequency drastically decreases, even by half. Consequently:
- Tears are not distributed evenly.
- The eye surface remains exposed to the air for longer.
- The aqueous layer evaporates rapidly, leaving the eye dry and irritated.
In addition to all this, aggravating environmental factors such as air conditioning in summer or heating in winter often contribute by reducing humidity in work environments.
What is evaporative dry eye?
Not all dry eye is the same. In most cases related to screen use, it is referred to as evaporative dry eye.
The tear film is composed of three layers, and the outermost one is lipid in nature (made of fats). The role of this layer is fundamental: it prevents the underlying water from evaporating too quickly. If the lipid layer is altered or thins due to infrequent blinking, the eye dries out rapidly, even if the glands produce tears.
To solve this specific problem, classic aqueous-based eye drops may not be enough, as they cannot restore the protective lipid barrier.
The practical solution: Lacrisek Plus Spray
For those who work many hours on the PC or for those who simply cannot tolerate the annoying sensation of a drop falling directly onto the pupil, there is a technological and decidedly more comfortable solution.
This is Lacrisek Plus Spray by Fidia, a medical device specifically formulated to counteract the alteration of the lipid layer of the tear film.
How does liposome technology work?
Lacrisek Plus Spray uses a formulation based on liposomes (composed of phospholipids), associated with Vitamin A and Vitamin E. When the spray is applied to the eyelids, the liposomes deposit on the eyelid margin and, with each subsequent blink, mix with the tear film, rebuilding and stabilizing the lipid component. This prevents premature tear evaporation and provides immediate relief.
The benefits of closed-eye application
One of the greatest strengths of this product is its mode of use: it is applied with closed eyelids.
- Absolute convenience: Ideal for those in the office or traveling who don't want to risk missing the target with a traditional bottle.
- Compatible with make-up: It can also be used over make-up (taking care to spray it at the correct distance of about 10-15 cm), without smudging.
- Hygiene and practicality: The compact 8 ml spray bottle is not easily contaminated and reduces waste.
Useful tips to prevent eye strain
In addition to using targeted supports such as tear substitutes, you can adopt some good daily habits to protect your eyesight:
- The 20-20-20 rule: Every 20 minutes of computer work, look away from the screen and focus on a point about 6 meters (20 feet) away for at least 20 seconds. This helps relax the eye muscles.
- Adjust screen position: The monitor should be about 50-70 cm from your eyes, with the top edge at eye level or slightly below.
- Use blue light filter lenses: If you spend many hours in front of digital devices, discuss with your trusted optician the use of glasses with specific anti-reflective lenses to block the blue light emitted by screens.
Take care of your eyes and don't underestimate the first signs of dryness. If you want to experience the effectiveness and convenience of this treatment, you can purchase Lacrisek Plus Spray directly online from our Ottica Paoletti store or visit us in-store for personalized advice.
