Cermin mata dan bingkai patah

Pagi ni, bila terjaga dari tidur aku terasa aku sedang berbaring di atas sesuatu yang keras. Bila aku check apa benda kat bawah badan aku tu, I found that it was my glass. The frame was broken. Luckily I had another glass. The other glass was multi-coated transition lens which is perfectly suitable for outdoor activities; but I don't really like it because the frame is a bit outdated. I'll use it when I have site visit and sort. The broken one used to be my normal wear. It was cheap,clear and very light. That's explain why that fast and easy.

Anyway, I want to do a new one today. So, I did some readings on the glass prescription and related stories. It was difficult to understand it so I end up with these lines in my blog. I'm a hyperopia (farsightedness) with a 2D degree of blur. Which one is suitable for me? The CR-39 or the polycarbonate.

"CR-39 is transparent in visible spectrum and almost completely opaque in the ultraviolet range, it has high abrasion resistance, in fact the highest abrasion/scratch resistance of any uncoated optical plastic."

"Polycarbonates are a particular group of thermoplastic polymers. They are easily worked, molded, and thermoformed; as such, these plastics are very widely used in the modern Chemical industry. Their interesting features (temperature resistance, impact resistance and optical properties) position them between commodity plastics and engineering plastics."

"Polycarbonate lenses are the lightest and most shatterproof, making them the best for impact protection. Polycarbonate lenses offer poor optics because of a low Abbe number of 31. CR-39 lenses are the most common plastic lenses, due to their low weight, high scratch resistance and low transparency for ultra violet and infared radiation."

OK then, I will go for the CR-39. Wait! There's more. This Essilor product making me more confused. Macam nilah, time now is 4:20 pm. It's still very super-duper hot out there. These days, the weather is extremely hot. It's the global warming. I would like to write about it later. Right now, let's go shopping!
