Purchasing a pair of sun glasses or shades is not matter to be taken lightly and is not similar to buying clothes and shoes as the right choice matters for our eyes! Most often, folks opt to buy low quality shades, which cause excessive damage to the eyes; hence prevention is definitely better than cure.
Let us first look at the benefits of using a pair of sunglasses;
01] Its fashionable
02] Reduces the sun’s glare
03] Protects the eyes from ultra violet radiations from the sun
04] Protects eyes from external hazards
According to the above, any pair of shades/ sunglasses sold in the market can be used for fashion, can reduce inconvenience caused by the sun’s glare and protect those peeps from external hazards, but to protect the eye from UV rays, it is compulsory to use a sun glass with UV blocking lenses.
In addition, the sun glass- lense- production method contributes to its quality. One way of producing lenses is by excessively heating and fitting the colorful flat glasses with a curved effect. Due to minor changes in the curvature of such lenses, the images visible to the eye can be somewhat blurred. Also, these lenses are not capable of blocking UV light.
The second method of producing sun glass lenses is the direct production of sun glass lenses. These lenses do not have above mentioned defects.
With these lenses, the UV blocking lens is also best suited for use as sunglasses.
Some folks choose to ignore these minor concerns regarding quality and choose shades at random but this may have a debilitating effect to the eyes. Once the naked eye is exposed to the sun the pupil contracts and a small amount of the sun’s rays goes in to the eye. In view of this, the UV rays also decreases.
