How to choose sunglasses?
In sunny weather, have an outdoor activity and give your mind and body a SPA. However, strong light can cause some damage to our eyes. How can we protect our eyes while enjoying the beautiful scenery freely? Choosing the right pair of sunglasses is the best choice! !
How to choose sunglasses? Choose tinted lenses or Polarized Lenses? After looking at the following two comparisons, I believe you will make a choice that suits you.
1.What are sunglasses?
Ordinary tinted lenses
The transmittance of the lens is reduced through the tinting process (immersion or coating), which reduces the light intensity, similar to the "sunglasses" effect. The depth of color (such as gray, brown, green) determines the degree of shading, but it cannot filter glare in a specific direction.
Polarized lenses
Adding a polarizing layer (polarizing film) on the basis of tinting is similar to the principle of "blinds", which only allows vertical light to pass through, and can effectively block horizontal glare reflected from water, snow, and road surfaces.
2.Core function differences
Ordinary tinted lenses
Sun protection : Reduce strong light and reduce eye fatigue.
Ultraviolet protection : Requires additional coating to achieve, not all tinted lenses have it.
Multiple color options : such as gray (natural color difference), brown (enhanced contrast), green (balanced color).
Polarized lenses
Glare elimination : For reflected light (such as water, glass, snow reflection), improve visual clarity.
Ultraviolet protection : Usually comes with UV protection (polarizing film superimposed coating).
Contrast enhancement : Reduce scattered light interference and make the field of vision sharper, especially in strong light environment.
3. Comparison of applicable scenarios
Ordinary tinted lenses
Daily sun protection (such as shopping, walking).
Environment with medium light intensity and no obvious reflection.
Polarized lenses
High-reflection scenarios : driving (reducing windshield reflections), fishing/skiing (glare on water/snow), outdoor sports (mountaineering, cycling).
Activities that require precise visual judgment (such as golf, skiing).
4. Differences in visual effects
Ordinary tinted lenses
Overall reduction in brightness, which may affect color authenticity (such as red lenses enhance contrast but have color cast).
Polarized lenses
Clearer vision, more natural colors, and more prominent details after glare is eliminated.
Note: It may affect LCD screen display (such as mobile phones, navigators) due to the conflict of polarization angles, causing the screen to darken.
5. How to choose?
Choose ordinary tinted lenses :
Limited budget, only basic shading is required.
Daily use, no high-intensity glare environment.
Choose polarized lenses :
Frequent driving, fishing, skiing or outdoor work.
High requirements for visual clarity, willing to pay for professional functions.
Notes
Polarized lenses are not suitable for night driving (too low light transmittance), you need to choose night polarized lenses (special coating).
When fitting glasses, polarized lenses may affect the accuracy of the degree due to thickness, and professional adjustment is required.
Summary : The essential difference between the two lies in whether they have the ability to filter polarized light . Ordinary tinted lenses are "basic sunshades", while polarized lenses are "professional anti-glare tools", you can choose as needed
