Researchers have linked ultraviolet (UV) light to the creation of cataracts. Disclosure to too much UV light also may effect in a state called photokeratitis.
That’s why a few contact lenses now integrate a UV blocking agent. You can not notify if contact lenses have a UV blocker just by looking at it, the UV blocker is offered in obvious form, so as not to disturb vision. The contact lenses packaging will state if the contact lenses product has a UV blocker or you can ask your eye doctor.
Very Significant: UV blocking contact lenses are not intended to replace sunglasses. A contact lens covers up only your cornea, not your whole eye.
Though, UV blocking contact lenses do assist protect the part of the white of your eye that is covered from structure of growths such as pingueculae and pterygia.
Sunglasses with UV protection can cover more of your eye and the components of your face that envelop the eye, depending on the size of the sunglass lenses. That’s why contact lenses by UV blockers are intended to match sunglass utilizing as an added safety.

Eye Makeup and Contact Lenses
Getting makeup in your eye is annoying. But it’s even worse with contacts, because it can stick to the lenses instead of flushing right out. Follow these tips to keep your eyes looking and feeling good:
Put in your contact lenses before applying makeup. And always wash your hands thoroughly before touching your contacts, so you won’t transfer any oils, creams, or lotions to the lenses.
Use only non-allergenic makeup. Almay and Clinique have eye-friendly products, but there are other brands as well.
Cream eye shadow is less likely to get in your eye than powder. However, creams can also irritate your eyes more if they do make it into your eyes. Choose water-based rather than oil-based creams.
If you prefer powder, keep your eyes closed during application. Then, brush off any excess powder before opening your eye.
Never apply eyeliner between your lashes and your eye. Apply eyeliner only on the portion of your lashes that is well away from your eye.
To remove eye makeup, wash and dry your hands. Then remove your contacts, being careful not to bump them into any makeup. Finally, use your eye makeup remover.
This composite NASA image of the spiral galaxy M81, located about 12 million light years away, includes X-ray data from the Chandra X-ray Observatory (blue), optical data from the Hubble Space Telescope (green), infrared data from the Spitzer Space Telescope (pink) and ultraviolet data from GALEX (purple). The inset shows a close-up of the Chandra image. At the center of M81 is a supermassive black hole that is about 70 million times more massive than the Sun.
A new study using data from Chandra and ground-based telescopes, combined with detailed theoretical models, shows that the supermassive black hole in M81 feeds just like stellar mass black holes, with masses of only about ten times that of the Sun. This discovery supports the implication of Einstein’s relativity theory that black holes of all sizes have similar properties, and will be useful for predicting the properties of a conjectured new class of black holes.
