Selecting the right frame depends on your face shape. For example:

• Oval faces: Most frame shapes work well.
• Round faces: Rectangular or angular frames add definition. 
• Square faces: Round or oval frames soften strong angles. 
• Heart-shaped faces: Oval or thin, light-colored frames balance features.

Common lens options include:

• Single vision lenses: For one field of vision (distance or reading).
• Progressive lenses: For multiple vision needs without visible lines. 
• Blue light filtering: Reduces eye strain from screens. 
• Anti-reflective coatings: Minimize glare and improve clarity.

You should update your eyeglasses whenever your prescription changes or if you notice discomfort or vision issues. It's recommended to have an eye exam annually to ensure your prescription is current.

Yes, most vision insurance plans, as well as FSA (Flexible Spending Account) and HSA (Health Savings Account) funds, can be used to purchase prescription eyeglasses. Check with your provider or retailer for accepted plans and the reimbursement process.

Buying eyeglasses online is safe and convenient, especially for single vision prescriptions. Ensure you have your current prescription and pupillary distance (PD) measurement. For complex prescriptions or progressive lenses, an in-person fitting with an optician is recommended for best results.
