Points to consider while choosing sunglasses:
- Always look for sunglasses that block 99 or 100 percent of UV radiation thereby protecting your eyes.
- Also see to it that the lenses are dark enough to filter out 75 to 90 percent of powerful sunrays that makes you squint.
- The lenses should not cause eyestrain, headache, and give ugly wrinkles.
- Use colors for your lenses that will help you see the world's true colour ie, grey, brown, or green. Avoid yellow or amber lenses they make it hard to distinguish the traffic signal.
