Are All Blue Light Glasses Created Equal?

Not all glasses are created equal. The difference between high quality and low quality blue light glasses can be found by comparing lens materials, blue light filters, anti-reflective coatings and frame materials.

In this video I'll be using Felix Gray to represent the high quality eyewear options.

Though Felix Gray sponsored the review, it could have been better as an unbiased review, with other products mentioned.

Im working in optical can i make eyeglasses and put amber colors with anti reflection coating on top

Oliver: I have a pair of Maui Jim Clear Lens Prescription ((MJO2100). Maui Jim themselves describe it as :- " Clear Ophthalmic Lens with "Computer" protection. That is the 1.67HEV Blue Light Protect lens."  & " That lens if neither blue or brown. It is a clear lens, with a film built in that protects against harmful blue light." . So my questions are:- (A) they use the term "film", so I suppose they are not the "built-in" type you describe? or are they? (B) Would you say these are the correct prescription Lens to supply, for someone who works a lot at a screen / mobile devices? Without going the whole hog and getting "computer glasses" and finally (C) although the glass lens is described by maui Jim as "clear" and they do not show an obvious tint of colour. On close inspection they do look a very very light brown/beige lens color. is this normal?  Thank you very much...

The difference between "molded plastic frames" and "Acetate frames" you mentioned in the video is not exactly accurate. BOTH required a form of injection and machining:

With molding, the machining happens on the mold itself, then, you would inject the melted plastic into the mold to mold the shape of the glasses frame. Injection molding may appear cheaper because most people doesn't see what happens in step one and the cost associated for the step 1 (creating the master mold). However, if you were to only mold 1 glasses frame out of it, the cost of the mold will be fully passed on to that ONE glasses frame, then, that is not a cheap exercise at all.

While with acetate, the acetate could be applied in layers, but are also "molded" into a block. THEN, you machine the shape of the frame out of the acetate block. Very often Acetate glasses are more expensive because you are milling more than 80% of the material out of the block, leaving you a frame, means there's a lot of material wastage, and because you need the machine to mill out acetate one by one, the production time increase, hence, cost increase.

When you pay for a pair of glasses made of acetate frame, a lot of your money actually gone to the time of one by one machining and the material that has been threaded out and thrown into the bin. That's why, most Acetate frames wouldn't' be made in large quantity, because making more wouldn't reduce the manufacturing cost, hence, why, there may be less quantity of them produced, i.e. more unique.

The 2 different manufacturing processes does not equate to better or worse precision or quality, it is purely different process used to achieve different purpose.

can u explain what is the difference between expensive bluelight / computer glasses?

[square]

can you have blue light in prescription glasses is the somting i have to ask my optician to add inn

[JSFrederic]

I understand that computer glasses have power in it because of computer screen being close and help reduce fatigue. Would't reading be close as well?

[JSFrederic]

Can a blue light glasses claim to block 99% blue light but still no orange/red tint?

Good info and I am the first who watch this video and doing a comment!

Y is there a huge craze over blue light filtering lenses with no scientific evidence that blue light causes fatigue?
