Prevent Cataracts Eyes With Prescription Sunglasses
One of the best investments a wearer of eyeglasses will ever make is the purchase of prescription sunglasses. These glasses can have your normal prescription and be tinted to protect your eyes from the sun.
Prescription sunglasses protect your eyes from harmful UV radiation. The same damaging rays from the sun that cause sunburn and skin cancer can affect you eyes, causing you to develop cataracts, which cloud the eyes. While cataracts can be removed by surgery, why take the chance of cloudy vision.
If you drive a car, you will need to have prescription sunglasses to be able to see and drive safely. While persons that only need reading glasses may still be able to get away with over the counter sunglasses, persons with astigmatism or who are near sited will need prescription sunglasses in order to see the dangers that lie ahead. This will allow you to see clearer than you can with clip on sunglasses.
Prescription sunglasses lenses are ground just like normal lenses for prescription glasses. They are then soaked in a tinting solution to add the color. The longer the lenses soak, the darker they become. Persons that are extremely light sensitive usually like to have their lenses tinted as dark as possible. This will block even more glare from the sunlight from getting into your eyes.
If you have never had a pair of prescription sunglasses, you are going to be amazed at the difference they will make in your vision on sunny days. Because these sunglasses are prescription quality, the lenses are optical quality plastic. Normal sunglasses actually distort images as the lenses are usually not ground to an optical quality. The sunglasses made by the dispensing optician are ground to an optical quality so that there is no distortion of the images you see.
Persons that normally wear bi-focal glasses sometimes only need single vision sunglasses. The choice will be with regard to your use of the glasses. If they are just for driving, then you do not need the readers added. However, if you are the type that likes to lounge in the sun while reading a book or magazine, you will find that you prefer the bi-focal sunglasses so that you can focus on the text in your book.
Check with the optical shop to see if there are discounts for purchasing two sets of glasses instead of just one. The second pair can be your sunglasses. If you need to wait to order the sunglasses, most states allow the prescription to be filled for up to a year, so you can wait a few months before you purchase your new prescription sunglasses.
