Traditional photochromic eyeglass lenses gradually darken in response to ultraviolet light. They remain clear or nearly so indoors and inside vehicles because window glass blocks most ultraviolet light rays. Although many people appreciate the convenience, others choose to order prescription sunglasses from an eye doctor instead. These consumers find that certain advantages connected with sunglasses outweigh the convenience factor.
Daytime Driving
Because of the protective glass in vehicle windows, traditional photochromic lenses do not respond well to ultraviolet light. This is a problem for people who prefer to wear darker lenses while driving during the day. In addition, many manufacturers have developed lenses that darken in response to visible light, a product specifically designed for driving. However, those lenses never become completely clear. As such, this is not always an option for everyone who wears glasses.
However, having a pair of prescription sunglasses can be especially appealing for people who drive a lot during daytime hours. Examples include delivery drivers and drivers of semi-trucks. Agricultural workers in tractor cabs and heavy equipment operators working behind a windshield also may prefer to wear sunglasses.
No Transition Time
Some individuals may feel annoyed about needing to wait for photochromic lenses to darken and fade back to clear. When walking outside into bright sunshine, they have to deal with the discomfort until the lenses fully darken. When going inside, their vision isn't clear right away because they are still wearing dark lenses. In contrast, sunglasses and regular glasses can be switched for immediate results.
More Control
Someone wearing photochromic lenses has no control over how dark or light the glass gets in any environment. Sunglasses are available in a broad range of hues and darkness levels, allowing consumers to choose exactly what they want for driving and outside activity.
Fashion
Many consumers want an extra pair of eyeglasses in the interest of fashion. They may like having a stylish pair to wear to outdoor events and activities. It's easy enough to keep the regular glasses in a purse or automobile glove box. Inside an eyeglasses case, the products are protected from breaking.
Making a Choice
By considering the advantages of prescription sunglasses, consumers are better informed when making a choice between those products and photochromic eyeglasses. The main advantage of lenses that automatically darken and regain clarity is convenience. However, sunglasses offer a few other distinct advantages. During an appointment for an eye exam, patients can ask the eye doctor and optician questions they have about these options. Contact an eye doctor for more information.

I began wearing eyeglasses at a young age, but as a child and teenager, when it came time to choose a new pair every year after my annual eye exam, my parents always let me choose the style and then chose the lens coatings and other options for me before they ordered them. After I moved out on my own as an adult and went to my eye exam and picked out my glasses alone, I was so overwhelmed by all of my glasses options that I had to call my parents for advice! Since then, I have dedicated myself to learning all about eyeglasses, so I can make the best choices on my own without my parents help. I have learned a lot about them and want to share what I have learned with others on a blog! I hope I can help you make the best eyeglasses decision!
