Choosing the right sunglasses: comfort and protection for your eyes

To choose the right sunglasses, it is essential to know the sun protection factor, which indicates the degree of visible light absorption (expressed as a percentage).

• Index 0 ( 0-20%): indoors and on overcast days
• Index 1 (20-57%): overcast skies
• Index 2 (57-82%): in fine weather
• Index 3 (82-92%): bright light, mountains and beaches
• Index 4 (92-97%): extreme brightness (not suitable for driving)

Depending on your activities, certain advanced technologies can improve visual comfort:

• Photochromic lenses: automatically darken or lighten depending on light intensity

• Polarized lenses: filter horizontal light to reduce glare, ideal for driving, water sports, and snow sports

The glare index does not guarantee protection against ultraviolet (UV) rays. However, exposure to UV rays without adequate protection can cause lasting damage to the eyes and lead to:

• cataracts,

• macular degeneration,

• corneal lesions.

All eyeglasses sold at Optique Moitzheim filter 100% of UVA and UVB rays in accordance with CE standards.

In addition, the optical quality of the lenses is essential: avoid lenses with bubbles, streaks, or impurities, which can strain your eyes and alter color perception.

Each glass color has specific properties, in addition to its aesthetic appeal:

• Gray: reproduces natural colors, neutral and comfortable

• Brown: increases contrast, ideal for nearsighted people

• Green: pleasant, slightly alters colors, suitable for people with hyperopia

• Yellow: increases contrast on gray days, but causes glare in sunlight

• Pink/Blue: changes colors, limited effectiveness, more decorative

The choice of color therefore depends on your personal taste, visual comfort, and optical correction.

• Always check the UV protection before purchasing.

• Adapt the protection index to your activities and lighting conditions

• Choose lenses of optical quality, without visible defects.

• Choose the color of your lenses based on comfort and your visual correction.
