On Sunday, March 29, 2026, at 2 AM, we will switch to daylight saving time. One less hour of sleep, brighter evenings... and a direct impact on our visual health, especially after 40.
At Varionet, certified opticians and lens manufacturers, we know that presbyopia is not just about "poor near vision." It also means greater sensitivity to eye strain, light variations, and screens. And the time change exacerbates these fragilities.
Why does switching to daylight saving time tire your eyes?
Moving the clocks forward by one hour disrupts our circadian rhythm. Direct consequences for your eyes:
Shorter sleep, which reduces nocturnal ocular recovery.
Prolonged screen exposure in the evening, favored by later daylight.
Abrupt light transitions between indoors and outdoors, particularly troublesome for presbyopes.
Result: stinging, dry eyes, headaches, and difficulty focusing on near or intermediate vision (computer, reading, DIY).
Presbyopia: a fertile ground for visual discomfort
After 40, the lens loses its flexibility. The eye has to make a greater effort to accommodate, especially at the end of the day. With the time change, this effort is amplified.
Classic single-vision lenses (like "magnifying glasses" from a pharmacy) only correct near vision. They leave your eyes to work alone for intermediate distances (screen, dashboard, workbench), which increases fatigue.
The Varionet solution: degressive lenses for all-terrain comfort
Varionet glasses are equipped with exclusive degressive lenses, designed by French opticians. Their advantage? They offer clear vision from 30 cm to over 1 m, without changing glasses.
✅ Near vision (reading, smartphone, sewing)
✅ Intermediate vision (computer, cooking, DIY)
✅ Optional blue light protection to reduce screen-related fatigue
Unlike single-vision lenses, Varionet lenses naturally support your eyes in all daily vision zones, thereby limiting accommodation effort and eye strain.
5 simple steps to smoothly transition through the time change
- Anticipate the shift: go to bed 10 to 15 minutes earlier starting Thursday evening.
- Enjoy natural light in the morning to recalibrate your biological clock.
- Limit screens 1 hour before bedtime or use blue light filtering lenses.
- Blink regularly and hydrate your eyes to combat dryness.
- Wear suitable glasses: a pair of Varionet reading glasses provides optimal visual comfort from breakfast to bedtime.
