Power of Sunglass
Introduction:
Sunglasses are a popular accessory that not only enhance our style quotient but also protect our eyes from harmful UV rays. The power of a sunglass refers to its optical power or the degree of curvature of the lens.
Options:
a) 0 Dioptre
b) 1 Dioptre
c) 2 Dioptre
d) 4 Dioptre
Explanation:
The correct answer is option 'A' which is 0 Dioptre. This means that a sunglass does not have any power or refractive property. In simple terms, it does not correct any visual problems like myopia or hyperopia. Its only function is to reduce the amount of light that enters the eye and protect it from harmful UV rays.
The lens of a sunglass is made of high-quality materials that are specially designed to block out UV rays. They also reduce glare and make it more comfortable to be outside on bright sunny days. However, the lens of a sunglass does not have any correctional power and cannot be used as a substitute for prescription glasses.
Conclusion:
In conclusion, the power of a sunglass is 0 Dioptre. It does not have any corrective power and is used primarily for protection against UV rays and glare. It is important to note that wearing sunglasses with UV protection is essential for maintaining good eye health and should be worn whenever one is exposed to sunlight.
