Ray-Ban Mega Balorama (RB2289 901/31): The undisputed legend of sunglasses in Black / G-15 Green. The exact same classic you see everywhere. What makes us different is that we adapt it exactly to your optical prescription — because a legendary look only works when you see clearly. Available prescription-adapted or solar.
Mega Balorama. The oversized, ultra-thick bold evolution of the classic active silhouette. Aligned with Ray-Ban's bold design trend, this model maximizes the frame thickness and temple size, adding eye-catching circular metal hinge rivets. At Centro Óptico Alpedrete, we specialize in prescription-adapting them so you enjoy a bold styling with perfect medical-grade vision.
You slide them on and immediately feel their distinct character. The premium propionate chassis provides a robust, highly protective wrap-around fit, keeping wind, glare, and dust away. The wide temples featuring the Ray-Ban raised logo offer an extremely secure hold. Its G-15 Green lenses deliver maximum visual comfort.
Ray-Ban manufactures this model in various calibers to accommodate different facial profiles. The manufactured calibers for this code are: 60 mm, 63 mm. If you need assistance choosing the ideal width for your cheeks, our optical team is standing by to help.
A curved, thick-profile frame requires tailored lens surfacing. At Centro Óptico Alpedrete, we calculate the optical center and digital beveling with prismatic compensation software to eliminate fishbowl distortions. Partnered with Shamir, Essilor, and Prats, your customized sun lenses are ready in 7 to 10 days.
When purchasing your glasses you will receive: (1) Original Ray-Ban Case to safeguard your frame and lenses, (2) Official manufacturer cleaning cloth/documentation, and (3) Our gifted premium, washable high-density digital cleaning cloth from Centro Óptico Alpedrete.

Are they heavy since they are so thick?
No, not at all. They are crafted from premium propionate, a highly durable yet lightweight material engineered to keep thick frames comfortable for all-day active wear.
Do thick frames hide thick prescription lenses?
Yes, definitely. The thick bezel of the Mega Balorama chassis is excellent at concealing the outer edges of high diopter lenses, resulting in a very clean aesthetic finish.
