Final answer:
To remove contact lenses, use lens cleaning fluid applied to a cloth, or water as a secondary option. A lens-cleaning tool is beneficial for maintenance. Contact lenses improve peripheral vision and correct corneal astigmatism by creating a uniform optical surface with the tear layer.
Step-by-step explanation:
If you intend to remove a client's contact lenses, it is recommended to use a little lens cleaning fluid applied to the cloth for safe and effective cleaning. In a situation where lens cleaning fluid is not available, water can be used in a pinch, although it's not the ideal solution. Having a lens-cleaning tool with a brush on one end and a lens pen on the other could greatly assist in maintaining the cleanliness and integrity of the lenses without causing damage.
Contact lenses offer several benefits over glasses, such as superior peripheral vision and the correction of some corneal astigmatism. The tear layer between the contact lens and the cornea fills in surface irregularities and helps create a uniform optical surface, improving vision quality. Skilled optometrists take into account any difference in curvature between the lens and the cornea, adjusting the power of the contact lens accordingly.
