Frequently Asked Questions (FAQs)
What is FSA/HSA?
FSA stands for Flexible Spending Account, which is an employer-provided account designed to save on taxes and pay for qualified expenses. The IRS sets limits on contributions from both you and your employer. It’s important to note that funds in the FSA expire at the end of each calendar year. You can use a debit or credit card linked to your FSA for qualified expenses, or you can personally pay and submit a receipt for reimbursement through your account manager.
HSA stands for Health Savings Account, which is a type of flexible spending account specifically for qualified medical expenses. By enrolling in a High Deductible Health Plan and opening an HSA, you can lower your monthly insurance premium. The HSA funds, which are tax exempt, can be used to pay for higher deductibles, copayments, coinsurance, and other health-related costs. The balance in your HSA rolls over from year to year, allowing you to save for future medical expenses.

What is pupillary distance?
Pupillary distance (PD) is a crucial measurement when ordering glasses online. It aligns the power of the lens with the center of your eye, determining the exact point through which you’ll be looking. You can measure your PD at home using a ruler, as demonstrated in this helpful guide from GlassesUSA.com. Alternatively, if you don’t have a ruler, you can use a credit card by following the YesGlasses guide for measuring PD with a credit card.
What are the main differences between lens types?
When ordering glasses online, you have three main options for lenses:
1. Single Vision Lenses: These lenses hold one prescription and are suitable for people with either nearsightedness (myopia) or farsightedness (hyperopia).
2. Bifocal Lenses: Bifocal lenses are typically prescribed for presbyopia, which is age-related farsightedness. They separate your distance prescription from your reading prescription with a distinct horizontal line.
3. Progressive Lenses: Progressive lenses accommodate your distance, mid-range, and reading prescriptions all in one lens. They allow for a smooth transition between different fields of vision.
