How long do 10 inch bass subwoofers usually last before they start to distort with typical use?
Is this for Home or Auto? I can only speak to Home units. I service units in retail stores. These subs are used everyday for 12 hours. The units are all good makes (avg $600 ea). On average they begin to fail in about two years. So about 700 days @ 12 hours a day.
***now if you are talkin about auto, i can answer that. 10s in a car can vary in their lifetime. Typical use also varies. You may play your music loud or low during a typical day. Everything adds up. Usually they blow or tear the voicecoil, but at an average lifetime, i would have to say, probably 1-2 years, depending on how loud you like your music.
Can a phoropter tests nearvision when the patient looks down?
The manual phoropter may be used to verify the glasses or contact lens Rx. The near vision correction (e.g., for "bifocal" or near reading) is verified by slightly converging (crossing) the two eyes during the exam. Generally the patient does not look down through the phoropter.
How do you get rid of air bubbles in contacts?
The best way I have found it to slowly close your eye and the gently rub your eyelid in a circular motion to get the bubble out. If you blink too quickly, the contact might fall out.
Can I clean soft contacts with hard contact solution?
Yeah I just did it and it worked fine. Make sure you rinse your contact off with cold water after using the hard contact solution, because it is thick almost like a gel and I don't know that it would feel great in your eye.
What causes fatty deposits in the eye?
Any disturbance in the lipid metabolism can cause such a case, most commonly manifesting as arcus senilis where the cornea is deposited with fatty material e.g. phospholipids and cholesterol, resulting in corneal opacity. Disturbances in the lipid metabolism can occur in cases such as: hypercholesterolemia, hyperlipoproteinemia and hyperlipidemia
Wow! The above answer is correct to an extent but needs additional information. The MOST COMMON reason for fatty deposits in the eye are age and heredity. Everyone in some way has some natural collection and pooling of fluids around the under eye area, The composition of our eye area makes it naturally prone to accumulation of fluids and fatty tissue deposits which collect under and around the eyes. This often is the cause of dark circles under the eye.
I'm 12 and I wear contacts they don't hurt at all it might feel like you have something in your eye for a while but it goes away after you blink a couple times. But the ones to just change your eye color burn if you don't know how to use them or handle them properly.
How do you find out your right and left eye power for buying contacts?
A prescription would be needed to determined the 'power' of each eye if you're ordering contacts. If you're unsure and/to unable to get an eye exam to determine your prescription, to be on the safe side order +0.00 OS and +0.00 OD.
When do you have to stop wearing contacts?
you should throw them out when they begin to feel uncomfortable or blurry, but mine usually last for heaps long before they feel uncomfortable and dry.

most contact lenses have a use by date, and tell you when to throw them out, but i dont believe that because companies do that so you can buy more of there products, but you will know yourself when you need new ones, :)

Call your optometrist. He/she is suppose to give you a schedule when to throw these out when you received your first batch of contacts. Most likely two weeks, but please call to make sure.
What types of lenses are used for action shots?
For action shots, fast prime lenses and versatile zoom lenses are commonly used. Fast prime lenses, like 35mm or 50mm with wide apertures (e.g., f/1.8 or f/2.8), allow for quick focusing and better low-light performance. Zoom lenses, such as 24-70mm or 70-200mm, offer flexibility in framing and composition, making them ideal for capturing dynamic scenes. Additionally, lenses with image stabilization can help reduce motion blur during fast-paced activities.

The dog's name was Stan and wouldn't be notable other than for the fact that he didn't see a car coming the day after he was fitted with the lenses and he was struck by the car and killed.

How good are focus progressives contacts?
I don't highly recommend them. The quality of vision with progressive contact lenses will never be as good as you would achieve with glasses. They are okay for occasional use but they just aren't bespoke enough to cater for your individual needs. If you don't want to wear glasses, try monovision with contact lenses. This means wearing one lens for distance work, and the other for close work. It takes some getting used to but the results are excellent.
