By holding up a #14 welder’s glass, or a mylar or glass solar filter, to your eyes and looking through it at the sun.

There are several methods of safe telescopic solar observing. The most straightforward is to use a pre-telescopic filter made of glass or mylar and coated with an energy-rejection coating. Since you observe the solar image with an eyepiece, this is called the "direct view" method. Or, you could use a dedicated solar telescope that contains built-in safety provisions. Another safe method when done properly is solar projection. See similar questions...

Yes, but NEVER LOOK DIRECTLY AT THE SUN THROUGH A TELESCOPE! To safely view the sun, you should use a projection system or solar filters that fit over the end of a telescope to block most of the light from the sun. They are made of aluminum. (See Observing the Sun for details). See similar questions...

Yes! There is plenty of light to be had, and large instruments are not needed, so this activity is particularly well suited to amateurs. See similar questions...

Always use a specific cleanser to remove eye make-up (Gentle Eye Make-Up Remover Lotion or Instant Eye Make-Up Remover if you wear waterproof mascara). Soak a cotton pad with lotion and place over the eyes for a few seconds, pressing very lightly with your hand, and gently wipe the eyes moving from the inside to the outside of the eye. Then gently cleanse any remaining traces of make-up from under the eye. See similar questions...

Yes. Never look at the Sun with your naked eyes, not even for a quick glance. Obey this rule and your retinas will thank you. Astronomers using telescopes on the ground observe with special filters that block out much of the Sun's light. There are kinds of 'safety glasses' you can use to look at the Sun briefly. However, unless you are very sure you have the right kind, it is better to project a light from the Sun on a wall or piece of paper and look at that. See similar questions...

Cataracts, macular degeneration, pterygiums (red, fleshy growths in the corner of the eyes), keratitis (snow-blindness), and eyelid cancer have all been linked to sun exposure. See similar questions...

There are medical reasons to wear a good sunglass (not necessary "branded" or expensive), not only for fashion but to protect the eyes from UV rays. Excessive exposure to the UV rays have been linked to skin cancer and certain eye diseases, such as pterygium, corneal damage, cataract and retinal degeneration. Most of the plastic lenses, whether with or without power, can be coated with 100% UV protection. See similar questions...

Answer: -- Dress warmly! The winter sky offers some of the best objects for a telescope and it is a shame to cut an observing session short because you didn't bundle up. Even if you live in a warm area, or view during other seasons of the year, you will be surprised how quickly the air cools at night. See similar questions...

Answer: -- Try to observe with a plan. Choose a few easy objects (large and bright) that can be seen from your location and time of year. Check one of the popular astronomy websites such as Sky&Telescope, http://skyandtelescope.com/ and Astronomy Magazine, http://www.astronomy.com/ for a list of objects currently visible in the night sky . Answer: -- The number on the eyepiece is the focal length of the eyepiece. It is not the magnification of the eyepiece . See similar questions...

Sometimes it is easier to match the eyelids if both are operated. You must be examined before Dr. Schiller can answer this question for you. See similar questions...

In the early phases of AMD, sometimes the signs and symptoms may appear in only one eye. However, AMD is a “bilateral” disease meaning that you have it in both eyes. In other words, the signs of the disease eventually appear in both eyes. See similar questions...

Spots and floaters are usually harmless. Read our Spots & Floaters article for details about the causes and symptoms, and how to determine if you need to see your eye doctor. See similar questions...

Eye cancer is a very rare kind of cancer that starts in or on the eye (on the surface, on the iris, or within the eye beneath the retina) or in the skin around the eye (the eyelid). Because it is so rare, it is best for a person diagnosed with eye cancer to seek treatment from someone who specializes in this field. A person can ask their doctor to refer them to an eye cancer specialist. See similar questions...

Eye exams are recommended periodically, with the interval differing for various age groups. In the first three years of infancy, a child should have vision checked along with normal pediatric checkups. Between the ages of three and six (the most crucial period of eye development) an eye exam should be scheduled every year or two. After that period, until adulthood, exams should be scheduled as necessary. During the twenties one should have at least one exam. See similar questions...

This pertains particularly in the tropics where the UV light, specifically between 9am-3pm, enhances the swelling of post-operative facial wounds. Prolonged and direct exposure to the sun during the first 3-4 weeks should be avoided. See similar questions...

The sun will not ruin your tattoo but it is best to keep it protected as your skin will be sensitive and a sunburn on top of a tattoo would be painful. Again, I advise applying a healing ointment to your tattoo such as locally made tamanu oil, Biafine or A&D. See similar questions...
