How to Pick Prescription Sunglasses
Choosing the right prescription sunglasses requires considering several factors to ensure both clear vision and a comfortable fit. Here's a step-by-step guide to help you pick prescription sunglasses:
1. Determine Your Prescription Needs:
- Visit your eye doctor and obtain an updated prescription specific for sunglasses. This will include information about your lens power (for nearsightedness or farsightedness), cylinder (for astigmatism), and pupillary distance (PD) measurements.
2. Choose the Right Frame:
- Pick a frame that fits comfortably on your face and offers adequate coverage for your eyes. Consider factors such as face shape, size, nose bridge width, and temple length.
- Select frames made of high-quality, durable materials that can withstand outdoor conditions.
3. Select Lens Materials:
- Opt for lenses made from materials that offer UV protection and are impact-resistant. Common choices include:
- Polycarbonate: Lightweight, durable, and provides excellent UV protection.
- Trivex: Similar properties to polycarbonate but slightly clearer.
- CR-39 (plastic): A good choice for low-impact activities and lighter prescriptions.
- Glass: Offers excellent clarity but is heavier and more susceptible to breakage.
4. Consider Lens Features:
- Polarized Lenses: These reduce glare, are excellent for outdoor activities, and enhance visual clarity and comfort.
- Photochromic Lenses (Transitions): Change from clear indoors to tinted outdoors, providing sun protection without the need for separate sunglasses.
- Anti-Reflective Coating: Eliminates reflections on the back surface of lenses, improving clarity and reducing eye strain.
- Mirror Coating: Adds a touch of style and provides additional sun protection.
5. Consider Lens Color:
- Choose a lens color that suits your needs and personal preferences.
- Gray: Maintains neutral color perception, making it a versatile choice.
- Brown/Amber: Enhances contrast, making it a good option for low-light conditions.
- Green: Offers high contrast and is especially useful for outdoor sports.
6. Adjust the Fit:
- Once you've chosen your sunglasses, ensure they fit properly. The bridge should sit comfortably on your nose, and the temples should be snug but not too tight.
- Ask your optician to make adjustments if needed. Proper fitting is crucial for comfort and optimal vision.
7. Purchase from a Reputable Source:
- Buy prescription sunglasses from a reputable optical store or eyecare professional who can verify the authenticity and accuracy of the prescription lenses.
Remember: Your eye doctor or optician is the best resource for guidance and personalized recommendations based on your specific needs. They can assist you in choosing prescription sunglasses that provide clear vision, protection, and comfort for your eyes.
