Do not allow the high power objective to tough the lenses
1. Always carry the microscope in an upright position with two hands. One hand should support the base and the other should be on the on the arm. Use lens paper and lens cleaning solution to clean the lenses on the microscope. Paper towel will scratch the lenses. Use a soft cloth to clean other parts of the microscope. Lens cleaning fluid and paper is a must. Do not substitute paper towel, which is far too coarse and will scratch the lenses. Always set your microscope on a clean, flat surface. 5. Always remove slides from the stage and rotate the nosepiece to the lowest power before returning the microscope to its storage area.
I had a small crack in my frames near the lense (should of popped out lenses) and fixed them with gorilla glue. I got a little bit on one of the lense, most came off with alcohol while the glue was still wet, once it dried, it was stuck there. I used nail polish remover to remove the glue, worked like a charm, it will take a bit of rubbing and wiping the lense, or lenses, but it should work, it did for me.
All microscopes have lenses. Some types of lenses are eyepiece lenses, objective lenses, and condenser lenses.
A lenses that curve outward is convex.A lenses that curve inward is concave.
When preparing a wet mount specimen for viewing, it should be covered with a coverslip. This thin piece of glass or plastic helps to flatten the specimen, prevent contamination, and protect the microscope's lenses. Care should be taken to lower the coverslip at an angle to avoid trapping air bubbles.
You should always store them in a contact lens container before you put them in again. This should have some contact lens solution in it, to sterilize the lenses. If they are disposables, then just throw them away and then you can buy contact lenses online
Do not allow the high power objective to tough the lenses
The may be made of glass or plastic, but in either case they ARE always actual lenses.
Diverging mirrors and lenses always produce virtual images that are upright and smaller than the object being viewed.
When shopping for contact lenses you should make sure that they are doctor prescribed. You should also consider buying them in bulk.
Smaller
If the lenses are properly cleaned before they are put back in, it shouldn't affect the eyes.But lens users should ALWAYS wash and thoroughly rinse their hands before touching the eyes, or handling contact lenses. Contamination under or inside the lenses can cause problems with eye surfaces (scratching, irritation, or infection).* If you suspect a problem with your lenses, consult your ophthalmologist right away.
Concave and Diverging
Diverging mirrors and lenses always produce virtual images that are upright and reduced in size. These images are located on the same side as the object being observed.
Yes, you could die from contact lenses by not puting them in right
You should always follow the instructions your eye care professional gave you or follow the instructions usually printed as a patient leaflet that is inserted into your contact lens box. Usually daily wear contact lenses should be thrown away after 6-8 hours or according to your ecp. Nowadays some lenses can be worn up to 6 days and nights without having to take them out. These lenses are manufactured and distributed by companies such as Johnson & Johnson (Vistakon), Cibavision (AirOptix) and some Bausch&Lomb.
