What type of metal is the metal part? I'm allergic to certain types of metal and want to make sure I don't have a bad reaction. Thank you!

Dear Customer, thank you for contacting Firmoo. The frame is made of metal material which is very lightweight, flexible but durable. However, if metal frames cause a reaction, nickel is usually the culprit because most metal frames are made of a nickel alloy. Moreover, if you are allergic to nickel, I would suggest you choose Titanium frames which are very popular because they are lightweight, durable, strong, and corrosion-resistant. Titanium frame can be made in a selection of different looks, from modern to classic. They are also hypoallergenic, and they retain their shape better than other metals. They bend according to force but retain their shape due to the resistance alloy provides. You can also check here for more information about our frame materials. Hope this is helpful. Please stay safe and healthy!

My current glasses is 51-23-148. however when I bought these last year, I didn't really look into the measurements. Is it a big of a difference for the temple length? Will I be comfortable wearing these?

Hi Jiya, we suggest getting a frame with a 1 or 2 mm difference from your current glasses. If your current glasses are too big/small, you can go up/down 1-2 millimeters (example 50 to a range of 48-50). If the temple arm of your current glasses is a bit long on you, this frame temple length size will work, however, the nose bridge distance has 17 mm measurement only and it might be too small for you. Choosing a perfect frame size online can be tough sometimes so recommend to kindly check how to measure eyeglasses size and find the perfect size. Thank you and have a great day!
