Is it possible to change clear lenses to transitional lenses?
No, clear lenses cannot be changed to transition lenses. Transition lenses have a special treatment that reacts to UV light to darken in sunlight, which cannot be added to regular clear lenses. You would need to purchase new transition lenses to have this feature.
How do self-tinting glasses work?
Self-tinting glasses, also known as photochromic lenses, contain photochromic molecules that respond to UV light. When exposed to UV radiation, the molecules in the lenses undergo a chemical process that causes them to darken, providing protection from sunlight. Once the UV light is removed, the lenses gradually return to their clear state.
What is the function of a nose piece in a microscope?
The nosepiece in a microscope holds and rotates multiple objective lenses, allowing the user to easily switch between different magnifications without needing to manually switch out lenses. This feature enables smooth and efficient transition between magnification levels during observations.
Are there any swim goggles that fit over glasses?
yes, as a matter of fact, there are hundreds of online stores that offer goggles that fit over glasses. websites like nextag.com offer goggles with prices around $36 to $140 depending on the quality and size.
What 2 things does a microscope have?
A microscope has lenses and an adjustable stage. The lenses magnify the specimen being observed, while the adjustable stage allows for precise positioning of the specimen under the lenses.

Is there sunglasses that you can also see with?
Yes, there are sunglasses available with lenses that can transition from dark to clear when exposed to sunlight. These lenses are called photochromic or transition lenses, allowing you to wear your sunglasses indoors or at night as they adjust in darkness.

How do photochromatic lenses work?
Photochromatic lenses are commonly called transition lenses. The lens is clear, but when exposed to the sun's UV rays, they will darken like sunglasses.
What are transition lenses and how do they work to darken in the sun?
Transition lenses are a type of eyeglass lenses that automatically darken when exposed to sunlight. They contain special photochromic molecules that react to UV light, causing the lenses to darken. When the UV light diminishes, such as when indoors, the lenses gradually return to their clear state. This allows the lenses to provide both vision correction and sun protection without the need to switch between regular glasses and sunglasses.
How do transition lenses work to darken in the sun and lighten indoors?
Transition lenses contain photochromic molecules that react to UV light. When exposed to sunlight, these molecules darken to protect the eyes from harmful UV rays. Indoors, where UV light is minimal, the molecules return to their clear state, allowing the lenses to lighten.
How much are transition lenses?
The price of transitions lenses will depend both where one buys them and exactly what type of transitions lens. Most of the time transitions lenses cost between $25 and $50 though can be as high as $100.
How do transition lens work?
Transition lenses contain photochromic molecules that darken when exposed to UV light, and become lighter when the UV light diminishes. This allows the lenses to automatically adjust to different lighting conditions, providing both clear vision indoors and UV protection outdoors.
How do self-tinting glasses work?
Self-tinting glasses, also known as photochromic lenses, contain photochromic molecules that respond to UV light. When exposed to UV radiation, the molecules in the lenses undergo a chemical process that causes them to darken, providing protection from sunlight.

Do tears damade contact lenss?
No.While crying, wearing lenses, the lense wouldn't be damaged: In fact, it might be cleaner. But it's still dangerous and not recommended to swim or take a shower with lenses.
Which bifocal lenses provide the smoothest transition from close-up view to far view?
try RGP bifocul lenses as a starting point but please check with an optomotrist becauses they can tell you which one is the best.
What makes transition lenses transition?
http://en.wikipedia.org/wiki/Photochromic_lenshotochromic lenses are lenses that darken on exposure to UV radiation. Once the UV is removed (for example by walking indoors), the lenses will gradually return to their clear state. Photochromic lenses may be made of either glass or plastic. The glass version of this type of lenses was first developed by Corning in the 1960s. More recently, plastic versions of these lenses have been commercialized. The first of these was the Photolite lens sold in the early 1980s by American Optical Corporation. The first commercially successful plastic photochromic lens was introduced by Transitions Optical in 1991.[1] The glass version of these lenses achieve their photochromic properties through the embedding of microcrystalline silver halides (usually silver chloride), or molecules in a glass substrate. Plastic photochromic lenses rely on organic photochromic molecules (for example oxazines and naphthopyrans) to achieve the reversible darkening effect. The reason these lenses darken in sunlight but not indoors under artificial light, is that room light does not contain the UV (short wavelength light) found in sunlight. Automobile windows also block UV so these lenses would darken less in a car. Lenses that darken in response to visible (rather than UV) light would avoid these issues, but they are not feasible for most applications. In order to respond to visible light, it is necessary to absorb it, thus the glass could not be made to be clear in its low-light state.
