Our optometrists suggest 3 essential elements to take into account when to choose the sunglasses that best suit you.
1. UV protection
Repeated exposure to UV radiation can cause serious eye problems.
The sunglasses you choose should offer 100% protection against UVB and UVA rays. Although UVB is known to be more harmful to the skin and eyes, doctors suggest avoiding both types of radiation. The lenses should also block UV rays up to a wavelength of 400 nm (nanometers).
In addition, you can take care of your eyes by choosing glasses with sunglasses polarized and anti-reflective. They reduce glare and offer the best UV protection, blocking all rays ultraviolet horizontal.
How to choose the right protection?
When choosing your sunglasses, make sure they are marked “CE”, followed by their sun protection factor. A number from 0 to 4 means that the tint of the lenses corresponds to the European legislation on UV protection. So it’s not just tinted lenses.
The filter index or sun protection category is pretty much the same thing. Both are determined by the amount of light filtered through the glass.
The higher the index, the more it reduces light intensity.
These glasses are usually comfortable sunglasses or fashion accessories. They hardly protect against glare. The filtering of UV A and UV B rays is too low to ensure a high level of sun protection effective.
Do not wear these sunglasses in strong sunlight or in the summer sun!
These glasses usually have a slight tintoften gray or pink-purple. They offer limited reduction of solar glare and have little UV protection.
The index 1 protects the eyes in case of weak sunlight or cloudy days.
These sunglasses offer good UV protection UV protection and a medium level of solar glare reduction.
Category 3 offers good protection against visible light and UV rays. These lenses block more than 80% of the light. Ideal glasses for places with strong sunlight such as the sea, the mountains, sunny cities or during winter sports.
Category 4 sunglasses are special purpose glasses that provide a high level of solar glare reduction. They offer exceptional UV protection, as they block more than 90% of the light.
They are therefore suitable for extreme light where the sun is reflected in the snow (mountaineering, glaciers, etc.).
Be careful, these glasses should not be worn while driving, they are too dark.
2. The shape of the face
The round faces have the same height and width. It is better here to choose sunglasses a little wider.
Rectangular or square sunglasses are good options for this face shape.
If you have an oval-shaped face, you can wear almost any frame you want. Darker colored lenses will accentuate your cheekbones.
You can even try the “Cat-eye” frames, back in fashion!
Square faces often have angular features that form a straight, clean line from forehead to jaw.
Slender, rounded frames that are slightly wider on the side can give a harmonious, natural look to square faces.
The frames round or oval will be ideal for this face shape.
Heart-shaped faces are wider at the forehead and narrow to the chin, with high cheekbones.
Cat eye frames, round glasses, small rectangular glasses and rimless glasses are good options for this face.
3. The color of the sunglasses
Colored sunglasses are not only a fashion accessory: they help filter the light!
The right lens tint improves your depth perception. It also reduces eye strain without affecting your ability to see clearly.
