2 responses to âSki Goggle Lens: How to Pick the Right Oneâ Virtually all snow goggles on the market offer 100 percent UV protection, but they vary in terms of VLT, or visible light transmission. VLT is listed by manufacturers as a percentage. For instance, a goggle lens for sunny days might have a 15-percent VLT that allows only 15 percent of the sunlight through the lens. Mirror finishes tend to knock down the VLT by a few more percentage points, so many bright-light lenses have such finishes.

What Are the Differences between an Ophthalmoscope and Otoscope? This is one of the main differences between an ophthalmoscope and otoscope, because the former is used for one purpose only, which is examining the eyes. Appearance is another difference between an ophthalmoscope and otoscope. The head of the ophthalmoscope is flat on both sides of the instrument and is not designed to come into contact with the eye. With the otoscope, the instrument has a cone-shaped tip that protrudes slightly on the side facing the patient and is inserted slightly into the patient's ear.

Even the most advanced hearing aids can’t restore your hearing to 100% the way another person can hear naturally. Glasses can restore your vision to 20/20.

Can you wear glasses and safety goggles at the same time? Yes, you can wear safety goggles over your prescription glasses. Keep in mind that not all goggles are designed to fit over prescription glasses, so make sure they're deep enough to provide enough room for your glasses.
