Selecting the right pair of sunglasses can be a challenge, as different types are suited to different needs. For example, cyclists often benefit from lightweight resin-made sunglasses, while athletes might prefer sports sunglasses with a larger curve for better coverage. People with farsightedness may find sunglasses clips or special optical sunglasses more comfortable. So, how do you choose the right sunglasses for you?
Key Features of Quality Sunglasses
A good pair of sunglasses should not alter the color of objects. Polarized lenses, typically made from lightweight synthetic resin, consist of seven layers: the outermost layers are super-hard and wear-resistant, the second and sixth layers provide shatter-proof reinforcement, the third and fifth layers filter UV rays, and the middle layer is the polarizing filter. Polarized lenses effectively block reflected light and harmful UV rays while offering durability against shattering and wear. These features make polarized sunglasses a popular choice.
How to Identify Quality Sunglasses
When assessing sunglasses, look for a pair that doesn’t distort your vision or make objects appear blurry. A simple test is to look at a playing card through the lenses; the colors should remain true to life. Poor-quality sunglasses may have issues such as misaligned lenses, uneven dyeing, or improper grinding, which can cause blurred vision, eye fatigue, and even long-term damage to your eyes.
Myth: Darker Lenses Offer Better Protection
Many people believe that darker lenses provide better protection against the sun. However, this is a misconception. The ability to block UV rays is determined by the lens’s UV standard, not the darkness of the tint. For example, UV400 lenses block 100% of UV rays, while UV100 lenses block 96-98% of UV rays. Therefore, when choosing sunglasses, focus on the UV rating rather than the darkness of the lenses. Dark lenses can actually impair visibility and strain your eyes if they allow too little light to pass through. Ideally, sunglasses should allow about 30% of light to pass through, with gray or green tints being the most recommended.
Tips for Selecting Reliable Sunglasses
To ensure you pick a reliable pair of sunglasses, consider the following:
- Examine the Lenses: Avoid sunglasses with scratches, impurities, or air bubbles. Hold the sunglasses up to a fluorescent light; if the reflection appears wavy or shows water-like patterns, the lenses are not flat and could harm your eyesight.
- Check the UV Protection Label: Quality sunglasses will have UV protection labels, indicating their ability to filter UV rays. Look for labels marked with UVA (320-420 nanometers), UVB (275-320 nanometers), or UV400 (below 400 nanometers).
- Test for Optical Clarity: Ordinary sunglasses should not have any optical “degree” or diopter. If the lenses have a diopter exceeding 15%, you may feel dizzy when wearing them. Optical shops can test this for you.
Recommended Lens Colors for Driving
When driving, the color of your sunglasses is crucial. Dark lenses can hinder your vision, while lenses that are too light might not filter out enough light. A simple way to assess your lenses is to put them on and look in a mirror; the ideal tint should allow you to faintly see your pupils.
For driving, brown or gray polarized lenses are recommended. Brown lenses filter out blue light, enhancing contrast and clarity, which is especially helpful in polluted or foggy conditions. Gray lenses evenly absorb all color spectrums, reducing brightness without distorting colors.
