If you do wear bifocals, though, you may want to get the opinion of an optician before committing to a purchase, so visiting a brick-and-mortar store that offers Bellagio frames to try on a few pairs will be in your best interest.
This remarkable feat is accomplished through photochromic technology, and even better is the fact that these special lenses are compatible with a wide range of prescriptions, including bifocals and trifocal recommendations.
If you didn't have bifocals, you'd have to take off one pair of glasses to replace them with a pair of readers every time you needed to shift from viewing something at a distance to looking at something up close.
Nobody will know you're wearing bifocals (important for those who are worried about looking young), and your prescription will gradually shift from your distance prescription to your near prescription.
If you have to wear eyeglasses for reading signs, watching television, driving, or other activities where the ability to see at a distance is required, you'll thank your lucky stars for your bifocals.
Since bifocal lenses often cost a bit more than single vision ones, bifocals that stick onto regular lenses are a good alternative for those who can't afford to spring for the pricier pair of lenses.
Previously, a fixed lens would be implanted, and although the patient's eyesight was improved, they still needed bifocals or tri-focals to be able to see clearly both close up and at a distance.
The good news is, even if you wear a complicated prescription (as with the bifocals, trifocals, and progressive lenses mentioned above), you won't have a hard time finding a pair of sunglasses that fit all your needs simultaneously.
Visionworks runs different promotions throughout the year, such as two pairs of eyeglasses for $99.00, one pair of prescription reading glasses for $29.00, and two pairs of no-line bifocals for $149.00.
Keep in mind that if you're currently wearing no line bifocals, you may not enjoy wearing the stick on variety, as there is a visible line and the shift from distance to near vision is more drastic.
