Testing contrast sensitivity helps to establish a record of what is normal for each patient, since everyone’s contrast sensitivity is unique. After establishing this accurate record for the patient, pinpointing abnormalities will be easier and can lead to quicker detection of vision problems. Abnormal contrast sensitivity results can help detect early signs of diseases such as Parkinson’s, Glaucoma, Cataracts and Glare problems, among many others.\n\nSloan low contrast vision test features equivalents on each side of the chart. These equivalents include Meters, Feet, LogMar, and Decimal. This list helps in easy translation and conversion of equivalents. Coupled with Sloan letters, true contrast levels and ETDRS style format, this contrast sensitivity test is accurate and reliable.\n\nWill fit illuminated cabinets \u003ca href=\"%%+logmar-chart-slim-cabinet-sussex-p-5539.html%%-\"\u003eSDT-392-LSV\u003c\/a\u003e and \u003ca href=\"%%+precision-vision-logmar-cabinet-p-5544.html%%-\"\u003eSDT-396-LPV\u003c\/a\u003e\n\nGlossary of terms:\u003cbr\u003e\n\u003ca href=\"%%+info_pages.php?pages_id=20%%-\"\u003e\u003cb\u003eWhat does ETDRS mean?\u003c\/b\u003e - Click for more info\u003c\/a\u003e\u003cbr\u003e\n\u003ca href=\"%%+info_pages.php?pages_id=17%%-\"\u003e\u003cb\u003eLogmar Definition \u0026amp; Protocol\u003c\/b\u003e - Click for more info\u003c\/a\u003e\n\u003c\/div\u003e","brand":"SV","offers":[{"title":"Default Title","offer_id":53796948148567,"sku":"SV-SDT-216-0","price":201.73,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1015\/4360\/8663\/files\/SDT-216-0.jpg?v=1781603762","url":"https:\/\/www.sussex-vision.co.uk\/products\/sloan-letters-contrast-chart-2m-1-25","provider":"ESP\/SV","version":"1.0","type":"link"}
