The sun emits three types of rays: visible, infrared and ultraviolet (UV).
The UV rays are what is most responsible for eye damage.
Exposure to bright sunlight over time can damage the cornea, lens and retina.
A few diseases cause by exposure to bright sunlight are known as pterygium (a fleshy growth on the corner of the eye), cataracts (clouding of the lens), and macular degeneration (a breakdown of the macula).
Hopefully after being educated on how serious exposure to harmful UV rays can be, people in general and also those using prescription glasses will choose quality sunglasses that are capable of blocking these harmful rays.
Prescription sunglasses are specially designed for people who have eye disorders but want to be more fashionable by not using the common spectacles.
Now many popular sunglasses companies such as Oakley and Revo make fashion appealing prescription sunglasses.
Prescription sunglasses are purchased based upon the power of the lens as prescribed by an oculist.
The special lens has the capability of either magnifying or diminishing images determined by the needs of the user.
Prescription sunglasses are designed to protect the user from the harmful ultraviolet radiations of the sun.
A special polarized lens can also help protect the eyes from glare from light reflecting surfaces such as water or snow.
Photo-chromatic sunglasses are becoming popular because of their ability to darken in the sun and lighten up indoors.
Until recently prescription sunglasses were not available in the wraparound style because any curvature of the lens would cause distorted vision.
Now the prescriptions are available with a little wraparound making them more fashionably appealing to consumers.
Custom made prescription sunglasses are generally higher priced and usually no refund is offered.
Make sure you work with a reputable company that offers quality prescription sunglasses and service.
