    Slit
In summary: The UK is somewhere in between. They do pretty much everything without drops, including looking at the retina. You may well find that it's not really necessary on 'your side' but they do it to justify charging you their fees. Is it snake oil in the dropper? lol.

At opticians they use slit lamps. Does anyone know if they are safe for the human eye (the light can be bright and annoying)? I'd imagine they'd have safety checks on that kind of stuff.

Anyone can answer?

Yes, it is safe. It's just a little bright.

If you were outside in the Sun and not in the dim examining room, I bet you'd hardly be able to see that slit of light that looks so bright. Your eyes can adapt to an amazingly big range of light levels, given a few minute to adjust.
I think one of the reasons for using low light conditions for eye testing is that you pupil is open wide and gives you much less depth of field, this making the test more sensitive.

Actually, they will generally use eye drops to dilate your eyes for such exams. They do that primarily so they can see more of the retina.

Eye drops are not used for regular eye testing ( not in Brighton UK). That includes the pressure test and view field. You don't want to see a test chart with eyes full of drops. The less invasive and more 'normal' the better.

Here locally in the US they do the eye exam first, with the eye chart, etc., and then put in the dilating drops and have you sit around for 10-15 minute while your pupils dilate for the rest of the exam. :smile:

You wait till Obamacare kicks in. The optician will ask you to read the number plate on a car outside and stamp you as A1 fit.

What is a slit lamp and how is it used in optometry?

A slit lamp is a specialized microscope used by optometrists to examine the health of the eye. It projects a thin beam of light onto the eye, allowing the optometrist to get a closer look at the different structures of the eye, such as the cornea, iris, and lens. It is an important tool in diagnosing and treating eye conditions.

Are slit lamps safe for opticians to use?

Yes, slit lamps are safe for opticians to use as long as they are trained and follow proper safety precautions. The light beam used in a slit lamp is not harmful to the eye, and the instrument itself is designed to be used in close proximity to the eye without causing any harm.

What safety precautions should opticians take when using a slit lamp?

Opticians should always wear protective eyewear while using a slit lamp to prevent any accidental exposure to light or debris. They should also make sure the patient's eyes are fully dilated before using the slit lamp and properly clean and disinfect the instrument between patients to prevent the spread of infection.

Can slit lamps cause any side effects or complications?

In general, slit lamps do not cause any side effects or complications when used correctly. However, patients may experience temporary discomfort or light sensitivity from the bright light used in the exam. If any problems or concerns arise during or after the exam, patients should consult with their optician or optometrist.

How often should slit lamps be serviced and maintained?

Slit lamps should be serviced and maintained regularly to ensure proper functioning and safety. The frequency of service may vary depending on the frequency of use and the manufacturer's recommendations. It is important to follow the manufacturer's instructions for cleaning and maintenance to keep the instrument in good working condition.
