For your lenses, a few simple steps and a visit to your eye doctor is all you need to find your prescription. Once you have it, you can begin shopping for glasses that will best suit your needs. It's important to keep in mind that not all prescriptions are created equal. Some prescriptions will require more specific lenses than others. For example, if you have a high prescription, your lenses will be thicker and will likely require a stronger frame. In general, the higher your prescription, the more expensive your lenses will be. That said, there are many trendy and affordable eyeglasses available from online retailers like LNKO. So don't let a high prescription scare you away from finding the perfect pair of glasses!
