Objective lenses are convex lenses.
who invented the bifocal lenses
Microscope objective lenses are the lenses that you can select on the microscope to change to field of view and magnification.
We use corrective lenses in spectacles. Near sight is corrected with diverging lenses and far sightedness with converging lenses.
you use two convex lenses.
In reference to Ray-Ban sunglasses, their GPL lenses are polarized. The GPL stands for Glass Polarized Lens.
A polarized lens cuts more reflected glare but the actual protection of polarized lenses and G15 lenses are the same. Polarized sunglass lenses reduce glare reflected off roads, bodies of water, snow, and other horizontal surfaces where the G15 lenses do not.
Yep. No difference in lenses except for the polarized coating.
Not all pairs are. You have to buy Polarized lenses for them to be polarized.
No. Polarized cost about $100 more.
no
I have heard several times that polarized lenses cause slight depth perception issues. A good article that discusses this is found at probaseballinsider.com. I found this article after a sunglsses salesman who played baseball suggested I would be better off without polarized lenses.
Polarized sunglasses are designed to vertically filter out glare from sunlight or bright lights. Self-tinting, or transitional lenses, are lenses that turn brighter or darker depending on the intensity of sunlight hitting the lenses.
No. Light bulbs produce non-polarized light.
UV lens coatings are designed to block UV rays from reaching your eyes. Polarized lenses block glare (light reflected off of water or snow, for example) and improve vision that way. Polarized lenses do not offer UV protection - they would need to have a UV coating applied.
Tint is mostly cosmetic. Polarized lenses block the harmful rays and are better for your eyes.
No they do not. Transitions cannot be tinted because it will not be effective. However, Polarized lenses can be tinted darker.
