Choosing A Pair of Sunglasses: Making an Informed Decision

Choosing A Pair of Sunglasses: Making an Informed Decision
The sunglasses you elect to wear are not just a fashion statement, or a way to look “cool” to your contemporaries or peers, they are also needed to safeguard your vision. Therefore, the sunglasses you choose to wear should not only complement your facial features, they should also be highly functional. As a result, a number of criteria must be considered before you make a sunglass purchase.
Don’t Just Look at the Frames – Look at All the Features of the Sunglasses You Buy
Like the looks of those aviator glasses or that designer brand of sunshades? Well, you also have to consider such things as UV light protection, polarization, and the lens color in addition to the frame. Ultraviolet or UV light is definitely a hazard to one’s optical health. Therefore, you need to buy a pair of sunglasses that will address this vision concern.
Do the Glasses Provide Sufficient UV Protection?
Not only do UV rays cause skin cancer, they can also cause such vision disturbances as macular degeneration and cataracts. While only about one percent of UV rays actually reach the earth’s surface, they still are a major worry for people who spend any amount of time outside. Therefore, a good pair of sunglasses should be designed to bar 98% or more of the optically unfriendly light. If they do not provide this kind of protection, you need to look for another pair.
Are the Glasses Polarized?
If you do a good deal of driving, then polarized glasses can help cut the glare from the roadways or from any oncoming traffic. Drivers who travel long distances are better able to see with polarized spectacles as polarization not only eliminates glare, it also increases the definition of objects and reduces eye fatigue.
Glare can indeed be a concern as it can cause eye pain and reduce visibility. While tinted lenses will absorb bright light, they cannot stand up to polarization when it comes to eliminating this kind of reflective light. However, that being said, lenses that are tinted do influence vision with respect to visual contrast and clarity.
The Color of the Lens
Therefore, lenses with a grey cast reduce the brightness of light but have no influence on colors or contrasts in the outdoor environment. Brown or green lenses, on the other hand, enhance depth perception, contrast and clarity. That’s why these colors are frequently used in sunglass designs.

      A little while back I lost my sunglasses, and I was curious about how I would get a new one for the summer. I really like that you say to find out if the glasses are polarized to help you while you are driving. Since I do drive around a lot in the afternoon, that would be a very nice thing to have.

      We'll be going on a tropical vacation soon, and I think sunglasses would be an essential accessory to bring with me. I like how you emphasized on looking for sunglasses that provide sufficient UV protection. I certainly don't want to harm my eyes any further. I'll be keeping this in mind.
