Beginning with the outer segment of the eye, the red-free filter can enhance intraocular pressure (IOP) measurements. The gold standard for IOP measurement, Goldmann applanation tonometry, uses cobalt blue light to accompany the instilled fluorescein dye. Alternatively, studies have suggested that IOP measured with the red-free filter and a topical anesthetic also yields accurate results. 4 For many patients, this method was better tolerated and more comfortable than traditional blue light with fluorescein and reduced the risk of accidental spillage with fluorescein dye and stained clothing. 4 It is also worth considering if topical fluorescein cannot be procured or if there is reason to suspect a fluorescein allergy.

There are several well-known monochromatic filters used on ophthalmoscopic examination. For example, the cobalt blue filter is frequently used, as it provides the necessary wavelength of illumination to excite fluorescein and better visualize the mires when performing Goldmann applanation tonometry. It is the often-underused red-free filter, however, that may be the most versatile. Rhodopsin (the chemical we use in night vision) is damaged by short wavelengths more than long ones, and by bright light more than dim light. So to best preserve night vision you need two things: light as dim as possible, and light as red as possible (i.e. long wavelength). Light that looks red in normal light can look orange, purple or white once the eye is fully adapted: this is because the light's spectrum includes short wavelengths. During a driving test, dealing with traffic lights will require a similar technique to dealing with junctions. The M,S,P,S,L (Mirror, Signal, Position, Speed and Look) routine must be applied.

Clean the external machine surface with a clean cloth (it is advisable to use an antibacterial solution), taking care to clean in all grooves and under the dispenser spout.
