Determine Your Vision Prescription
The first step in choosing bifocal sunglasses is to determine your vision prescription. Consult with an optometrist to complete an eye exam, and get an accurate prescription before purchasing bifocal sunglasses. Getting the right prescription is essential since bifocal lenses come in various diopters. The diopter values for the top section and the lower section of the bifocal lenses vary to match individual needs, so it is imperative to have the right prescription to prevent any issues later on.Choose the Right Tint
Bifocal sunglasses typically come in several tint and color options, ranging from clear to dark. The amount of light transmission determines the tint you choose. A high light transmission lens is suitable for low light conditions, whereas a lower light transmission is suitable for bright conditions. In addition, different colors can enhance your vision in specific environments; therefore, it is essential to match the environment you'll be wearing your glasses to get the optimum benefit.Consider Lens Material
Bifocal sunglass lenses are made from various materials, and each has its properties. The three typical materials used in making bifocal lenses include polycarbonate, trivex, and glass. Polycarbonate lenses are strong, durable, impact-resistant, and lightweight, making them ideal for sports activities. Trivex lenses are lightweight, thin, and more comfortable to wear than other materials. Glass lenses provide excellent optical quality but are more delicate and heavier than polycarbonate and trivex.Frame Considerations
Frames contribute to the overall appearance, comfort, and durability of your bifocal sunglasses. When selecting frames, it is essential to consider several factors such as material, style, weight, and size. Metal frames are generally more robust than plastic frames, but plastic frames are more comfortable to wear. If you have a larger head, it is essential that you choose a big frame size, and similarly, smaller frames should be chosen for smaller head sizes. A comfortable frame, combined with a perfect fit will ensure that your glasses stay in place, and you'll be able to wear them for an extended period without discomfort.UV Protection
Bifocal sunglasses provide dual functions of both vision correction and UV protection. Ensure that the lenses you choose have a 100% UV protection coating, which will protect your eyes from harmful UV rays. It is also essential to consider the wraparound design, which stops light from entering your eyes from the sides, providing optimal protection.Polarization
Polarized bifocal lenses are beneficial since they reduce glare and provide a better view in bright environments but should be reserved for use in specific conditions. When wearing polarized bifocal lenses, it can be difficult to read liquid crystal displays or see icy patches when skiing. If you will be operating machinery or driving, be sure to avoid using polarized bifocal lenses, as it can be challenging to read digital screens and gauges.Cost and Quality
Bifocal sunglasses vary in price, and quality often correlates to cost, so spending a little more can result in a better product. Keep in mind that you are purchasing bifocal lenses, which are more expensive than regular lenses, and therefore, be prepared to pay a premium for quality. However, this additional investment is worthwhile for most people since bifocal sunglasses offer the convenience of vision correction and UV protection in a single product.Conclusion
Purchasing bifocal sunglasses can be different from choosing regular sunglasses due to the additional considerations such as prescription, lens material, frame considerations, UV protection needs, and the need for glare reduction. By using these tips and considering your specific needs, you can find the perfect bifocal sunglasses to fit your needs. Remember, choose quality over price, and pair your sunglasses up with other sun-safe habits such as wearing hats and staying out of the sun, and you can enjoy optimal protection from harmful UV rays.Related Topics You Might Like
